Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common rectifier device is used for both wired and wireless connection devices, then device complexity is reduced and space is saved, but the ability to operate both connection devices simultaneously is limited
Solution Approach 1:
The patent implements a dynamic switching mechanism that allows the rectifier device to reconfigure its operational state based on charging requirements. The switching device enables transition between different operational modes: single-mode operation (either wired or wireless), and dual-mode operation (both wired and wireless simultaneously). This dynamic reconfiguration resolves the contradiction by making the system adaptable rather than fixed, allowing simultaneous operation of both connection devices when needed while maintaining simplicity in each individual mode.
2Adaptability or versatility
If multiple rectifiers are connected in parallel to support simultaneous operation of both connection devices, then operational versatility is improved, but device complexity and installation space increase
Solution Approach 1:
The patent segments the rectifier device into multiple independent rectifier units (first rectifier and second rectifier) that can be connected in parallel. Each rectifier unit is independently controllable through switching devices, allowing selective activation based on operational requirements. This segmentation enables simultaneous operation of both wired and wireless connection devices when both rectifiers are activated, while still allowing single-mode operation when only one rectifier is needed, thus balancing versatility with manageable complexity.
3Adaptability or versatility
If the energy supply device supports both wired and wireless connection methods, then adaptability is improved, but the installation space and device complexity increase
Solution Approach 1:
The patent merges the wired connection device and wireless connection device into a single integrated energy supply device housing. Both connection devices share common components including the rectifier device, switching devices, and control unit. This consolidation allows the system to support both wired and wireless charging methods simultaneously while minimizing installation space by eliminating redundant components and utilizing shared infrastructure within a compact unified structure.
