Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery capacity is increased to extend wearable device usage time, then device portability and comfort are compromised due to larger size and weight
Solution Approach 1:
The system enables self-charging through human body movement. The power generation device converts mechanical energy from arm or leg movements into electrical energy, allowing the battery to recharge automatically during normal wear without requiring external power sources or increasing battery capacity.
Solution Approach 2:
The power generation system transforms static energy storage into dynamic energy generation. Instead of relying on a large static battery, the system dynamically generates electricity through motion, adapting to the user's activity level and providing continuous power during movement.
2Duration of action of moving object
If battery capacity is increased to extend wearable device usage time, then device size is increased making it less portable
Solution Approach 1:
The system enables self-charging through human body movement. The power generation device converts mechanical energy from arm or leg movements into electrical energy, allowing the battery to recharge automatically during normal wear without requiring external power sources or increasing battery capacity.
Solution Approach 2:
The power generation system transforms static energy storage into dynamic energy generation. Instead of relying on a large static battery, the system dynamically generates electricity through motion, adapting to the user's activity level and providing continuous power during movement.
3Reliability
If frequent charging is required to maintain wearable device operation, then user convenience and lifestyle flexibility are reduced
Solution Approach 1:
The system enables self-charging through human body movement. The power generation device converts mechanical energy from arm or leg movements into electrical energy, allowing the battery to recharge automatically during normal wear without requiring external power sources or increasing battery capacity.
Solution Approach 2:
The system ensures continuous power generation through dual-power generation structures that can work alternately or simultaneously. The first and second power generation devices convert mechanical energy from different body movements into electrical energy, maintaining continuous charging during various activities.
