Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a conventional battery is used in mobile devices, then the device structure remains simple, but the battery life is limited and requires external charging
Solution Approach 1:
The patent combines multiple energy storage components (primary battery, secondary battery, solar cell) into a single integrated power system. The primary battery and secondary battery are electrically connected in parallel with the solar cell, creating a unified energy supply system that eliminates the need for separate charging devices and extends operational duration without proportionally increasing complexity.
Solution Approach 2:
The solar cell serves multiple functions: it acts as an energy source during daylight, a charging source for the secondary battery, and provides supplemental power to extend overall system operation. This multi-functionality addresses the limited battery life problem while avoiding the need for dedicated external charging equipment.
2Duration of action of moving object
If solar cells are integrated into mobile devices, then battery life is extended, but the device weight increases
Solution Approach 1:
The patent employs thin-film solar cells with selective light absorption properties optimized for specific spectral ranges. This localized optimization of material properties allows the solar cells to achieve higher efficiency per unit weight, extending battery life without proportionally increasing device weight.
Solution Approach 2:
The power system uses composite material structures including thin-film solar cells deposited on flexible substrates, combined with lightweight battery components. This composite approach achieves the desired energy storage and generation capacity while minimizing overall weight compared to conventional thick-film solar panels and traditional battery assemblies.
3Power
If multiple battery layers are stacked to triple energy supply, then power capacity increases, but manufacturing precision requirements increase
Solution Approach 1:
The patent divides the power system into distinct modular segments: a primary battery unit, a secondary battery unit, and a solar cell assembly. Each segment is independently manufactured and tested, then assembled together. This segmentation allows for standardized manufacturing processes with relaxed precision requirements compared to monolithic designs, while achieving tripled power capacity through the combined units.
