Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If incremental charging or frequent longer term charging is applied to extend battery operation, then battery operation duration is improved, but battery lifespan is significantly diminished due to limited charging cycles
Solution Approach 1:
The power source is segmented into two distinct components: a battery with limited charging cycles and a power buffer with high charging cycle capacity. The power controller segments the power delivery function, directing short-duration high-volume power needs to the power buffer while reserving the battery for prolonged low-volume needs, thereby resolving the contradiction between extending operation duration and preserving battery lifespan
Solution Approach 2:
The power buffer acts as an intermediary component between the power source and the power consuming body. It absorbs short-duration power demands that would otherwise deplete the battery, allowing the battery to maintain charge and extend its operational life while still meeting overall power requirements
2Duration of action of moving object
If battery size is increased to provide continuous power for longer operation, then power delivery capability is improved, but device weight and size constraints are worsened
Solution Approach 1:
The power storage function is segmented between two components with different characteristics: the battery provides prolonged low-volume power at optimized size/weight, while the power buffer handles short-duration high-volume demands. This segmentation allows the battery to be smaller and lighter than a single battery system would require, while still achieving continuous power delivery
Solution Approach 2:
The power controller dynamically switches between power sources based on real-time power demands. By dynamically allocating power delivery tasks between the battery and power buffer according to their respective strengths, the system achieves continuous power delivery without requiring an oversized battery
3Adaptability or versatility
If the battery is used to satisfy all power needs including short duration or high volume needs, then power delivery flexibility is improved, but battery charging cycles are depleted faster reducing overall lifespan
Solution Approach 1:
The power delivery function is segmented by demand characteristics: the power buffer handles short-duration and high-volume needs, while the battery handles prolonged and low-volume needs. The power controller manages this segmentation dynamically, maintaining power delivery flexibility while protecting the battery from excessive charging cycle depletion
Solution Approach 2:
Different parts of the power delivery system are assigned different functional qualities based on their characteristics. The power buffer is optimized for high-capacity short-term delivery, while the battery is optimized for sustained low-power delivery. This local quality assignment allows versatile power delivery while preserving battery lifespan
