FT Schools - Apple battery supplier takes on smart glasses rivals
FT Schools - Apple battery supplier takes on smart glasses rivals

Introduction
TDK, originally known for inventing high-quality cassette tapes in 1968, has evolved into the world’s largest smartphone battery supplier, supplying firms such as Apple, Huawei, and Xiaomi. It is now expanding into smart glasses using AI, sensors, and eye-tracking technology. The company is investing heavily in innovation and R&D to compete in the fast-growing wearable technology market focused on lightweight, power-efficient devices.
TDK has also acquired SoftEye to enhance its AI, eye-tracking, and software capabilities for smart glasses. However, TDK faces strong competition, geopolitical supply chain risks, and ethical concerns around AI-driven data tracking and eye health. These challenges highlight the importance of CSR and managing stakeholder conflict between innovation, profitability, and consumer safety in a high-tech industry.

Read the FT article here and then answer the two sets of questions:
Set 1 (SL)
| (a) | State two features of a takeover as a form of external growth. | [2 marks] |
| (b) | Explain one advantage and one disadvantage of growth through acquisition of SoftEye for TDK. | [4 marks] |
| (c) | Using Ansoff’s matrix, explain two reasons for TDK’s strategic move into smart glasses. | [4 marks] |
Answers
(a) State two features of a takeover as a form of external growth. [2 marks]
Possible answers include:
- One company gains control of another by purchasing the majority of its shares.
- The acquired firm becomes part of the acquiring company’s ownership structure.
- It may result in synergy through combined resources, technology, or expertise.
- It leads to rapid external growth without internal expansion or resources.
- Accept any other relevant feature.
Mark as a 1 + 1.
(b) Explain one advantage and one disadvantage of growth through acquisition of SoftEye for TDK. [4 marks]
Advantages include an explanation of any one of the following:
- Provides access to advanced AI and eye-tracking technology, speeding up TDK's smart glasses development.
- Enables TDK's rapid external growth compared to building capabilities internally through R&D.
- Creates potential synergies, combining SoftEye’s software expertise with TDK’s hardware (batteries/sensors).
- Accept any other relevant advantage explained in the context of the case study.
Disadvantages include an explanation of any one of the following:
- High acquisition cost of taking over SoftEye, thereby increasing financial risks for TDK.
- Possible integration problems between different company policies, processes, cultures, and systems.
- Risk that expected synergies or innovation gains from SoftEye may not materialise, reducing overall effectiveness and reputational risks for TDK.
- Accept any other relevant disadvantage explained in the context of the case study.
Mark as a 2 + 2.
Award [1] for each relevant advantage/disadvantage and [1] for explaining this in the context of TDK, up to the maximum of [4].
(c) Using Ansoff’s matrix, explain two reasons for TDK’s strategic move into smart glasses. [4 marks]
Possible answers include an explanation of any two of the following:
- Product development - TDK is creating smart glasses, a new product, to sell to existing/related markets in the consumer electronics industry. This creates additional revenue streams for the company.
- Diversification - TDK is entering a new market (consumer wearables) with new products, reducing its reliance on batteries. This helps the company to spread risks across markets and products.
- Growth opportunities - Ansoff's matrix outlines various growth strategies for businesses. Smart glasses are a fast-growing industry, offering higher long-term revenue potential than mature battery markets.
- Competitive pressures - Diversifying helps TDK respond to Chinese and US rivals and maintain technological relevance in growing and evolving consumer markets.
- Accept any other relevant explanation, written in the context of the case study.
Mark as a 2 + 2.
Award [1] for identifying a relevant reason and [1] for explaining this in the context of TDK, up to the maximum of [4].
Set 2 (HL)
| (a) | Define the term artificial intelligence (AI). | [2 marks] |
| (b) | Explain two reasons why research and development (R&D) are important for TDK’s success in the wearable technology industry. |
|
| (c) | Explain one advantage and one limitation of innovation for TDK in the wearable technology industry. | [4 marks] |
Answers
(a) Define the term artificial intelligence (AI). [2 marks]
Artificial intelligence (AI) is the development of management information systems that can perform tasks that normally require human intelligence, such as machine learning, decision-making, and problem-solving.
Award [1] for a definition that shows limited knowledge of artificial intelligence.
Award [2] for a definition that shows clear and accurate understanding of artificial intelligence, similar to the example above.
(b) Explain two reasons why research and development (R&D) are important for TDK’s success in the wearable technology industry. [4 marks]
sible answers include an explanation of any two of the following:
- Product innovation - R&D enables TDK to develop advanced smart glasses features such as AI, sensors, and retina projection.
- Competitive advantage - Continuous R&D helps TDK differentiate its products from Chinese and US rivals in the growing and competitive consumer wearable market.
- Cost and efficiency improvements - R&D can improve battery life and reduce power consumption (as mentioned in the FT article), making TDK's devices more efficient and attractive to consumers.
- Long-term growth - Investment in R&D allows TDK to enter and expand in fast-growing markets like AI wearables, ensuring future profitability.
Mark as a 2 + 2.
Award [1] for each relevant reason and [1] for explaining this in the context of TDK, up to the maximum of [4].
(c) Explain one advantage and one limitation of innovation for TDK in the wearable technology industry. [4 marks]
Possible advantages include an explanation of any one of the following:
- Innovation creates product differentiation, helping TDK stand out in the competitive wearable technology market.
- It supports new revenue streams by enabling TDK's entry into high-growth markets like smart glasses.
- It improves competitive advantage and product appeal through advanced features (such as AI, sensors, and low power consumption).
- Accept any other relevant advantage explained in the context of the case study.
Possible limitations include an explanation of any one of the following:
- High R&D costs increase financial risk for TDK, especially if the innovations fail to appeal to customers.
- Uncertain success rate, as new technologies may not be commercially viable (which is partially why TDK has acquired SoftEye).
- Rapid technological change can make innovations quickly obsolete, requiring continuous investment. This can create liquidity or bugeting issues for TDK.
- Accept any other relevant limitation explained in the context of the case study.
Mark as a 2 + 2.
Award [1] for each relevant advantage/limitation and [1] for explaining this in the context of TDK, up to the maximum of [4].
