Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rechargeable battery is used in a hearing device, then the hearing device can be recharged and reused, but the user must detach and recharge the device when the battery runs out, which is inconvenient and reduces user friendliness
Solution Approach 1:
A battery assembly with an inductive coil and electronic circuit is introduced as an intermediary component. This assembly converts direct current from a portable direct current source to alternating current, enabling external powering of the hearing device through inductive charging. The intermediary battery assembly acts as a bridge between the portable power source and the hearing device, allowing continuous operation without detaching the device.
Solution Approach 2:
The battery assembly is prepared in advance with a portable direct current source that can be activated when needed. The electronic circuit and inductive coil are pre-configured to enable immediate external powering of the hearing device when the internal battery is depleted, eliminating the need for detachment and recharging interruptions.
2Reliability
If a portable emergency power source is added to the battery assembly, then continuous use of the hearing device is enabled, but the device complexity increases
Solution Approach 1:
The battery assembly is designed to perform multiple functions: it serves as both an inductive charging interface and an external power source through the integrated electronic circuit and inductive coil. The same inductive coil used for charging also enables external powering when activated by the portable direct current source, reducing the need for separate components and minimizing overall complexity.
Solution Approach 2:
The electronic circuit and inductive coil are integrated into a single battery assembly unit that combines charging and emergency power functions. The portable direct current source is attached to this integrated assembly, creating a compact multi-functional component that reduces overall system complexity compared to having separate charging and power backup systems.
