Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If internal battery capacity is increased to extend battery life, then duration of action is improved, but device volume and weight increase
Solution Approach 1:
The power system is segmented into two independent parts: the device's internal battery and the external smart strap battery. This allows the battery capacity to be extended without increasing the volume of the main device, as the additional power source is placed externally on the wristband.
Solution Approach 2:
The power source is moved from the two-dimensional plane of the device body to a separate wearable dimension (wristband). This transfers the volume burden from the device to an external accessory worn on the user's wrist, effectively extending battery life without compromising device compactness.
2Duration of action of moving object
If internal battery capacity is increased to extend battery life, then duration of action is improved, but device weight increases
Solution Approach 1:
The power system is divided into separate components with the additional battery capacity placed in the external smart strap rather than integrated into the device. This segmentation transfers the weight of extended battery life from the device to the wearable accessory.
Solution Approach 2:
The additional battery weight is relocated from the device body to the wristband dimension. Users wear the weight on their wrist rather than carrying it in the device, achieving extended battery life without increasing device weight.
3Strength
If a rigid battery housing is used to protect batteries, then strength is improved, but flexibility and wearability deteriorate
Solution Approach 1:
The battery housing uses flexible materials such as silicone or rubber that can bend and conform to the wrist. This flexible shell provides necessary protection against impact and environmental factors while maintaining the softness and flexibility required for comfortable wearability.
Solution Approach 2:
The housing combines multiple materials with complementary properties: flexible polymers for bendability and comfort, integrated with protective layers that provide impact resistance and structural strength. This composite construction achieves both protection and flexibility simultaneously.
