Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery is used as the power source for the light-emitting device, then the device can function reliably, but environmental pollution occurs when the battery is exhausted or damaged
Solution Approach 1:
The invention extracts and eliminates the battery component from the wearable light-emitting system. By removing the battery as the power source and replacing it with a power-generating module that converts mechanical energy from body motion into electrical energy, the system maintains functionality while eliminating the harmful environmental impact of discarded batteries
Solution Approach 2:
The power-generating module enables the light-emitting device to generate its own power through body motion during daily activities. This self-service mechanism converts the user's natural movements into electrical energy, eliminating the need for external battery power sources and their associated environmental problems
2Ease of operation
If a battery is used as the power source, then the light-emitting device can be activated, but the device becomes non-functional when the battery power is exhausted or damaged
Solution Approach 1:
The invention transitions from a static battery power source to a dynamic power-generating module that continuously converts mechanical energy from body motion into electrical energy. This dynamic system ensures continuous functionality as long as the user is moving, eliminating the reliability issues associated with exhausted or damaged batteries
Solution Approach 2:
The power-generating module enables the device to generate its own power through the user's natural body movements during daily activities. This self-service approach ensures continuous operation without dependency on depleting battery resources, maintaining both ease of operation and reliability
3Ease of manufacture
If a battery is used in the wearable object, then the light-emitting function is achieved, but the device complexity increases due to battery management requirements
Solution Approach 1:
The invention removes the battery and its associated management systems from the wearable device. By extracting this complex component and replacing it with a power-generating module that directly converts mechanical energy to electrical energy, the overall device complexity is reduced while maintaining the light-emitting function
Solution Approach 2:
The power-generating module provides self-service by automatically converting body motion into electrical power without requiring battery management circuits, charge controllers, or power monitoring systems. This simplifies the device architecture while achieving the same light-emitting functionality
