Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a power supply system uses wired charging with a plug and cord, then stable electrical connection is achieved, but device portability and ease of operation are reduced
Solution Approach 1:
The patent replaces the mechanical wired connection system (plug and cord) with a wireless electromagnetic field-based power transfer system. The transmitter unit generates an electromagnetic field that inductively couples with the receiver unit, eliminating the need for physical plug insertion and cord management while maintaining reliable power transfer.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary medium between the power source and the device. The transmitter converts electrical energy to an electromagnetic field, which then transfers energy to the receiver without requiring direct physical contact, thus solving the contradiction between connection stability and portability.
2Ease of operation
If a power supply system uses wireless charging, then device portability and ease of operation are improved, but stable electrical connection during orientation transitions is compromised
Solution Approach 1:
The patent employs dynamic elements including spring-loaded electrical contacts that automatically adjust their position and pressure to maintain stable connection during device orientation transitions. The spring mechanism compensates for movement and misalignment, ensuring continuous reliable contact between the plug and power connector regardless of device orientation.
Solution Approach 2:
The patent segments the power supply system into modular components: a transmitter unit, a receiver unit, and a detachable cord assembly with plug. This segmentation allows the wireless charging components to remain stationary while the cord and plug can be repositioned independently to maintain optimal connection during orientation changes.
3Productivity
If a power supply unit integrates wireless charging circuitry and power connectors, then power management efficiency is improved, but device complexity increases
Solution Approach 1:
The patent merges the wireless charging transmitter circuitry, power regulation components, and electrical connectors into a single integrated power supply unit. This consolidation eliminates the need for separate charging devices and cables, reducing the number of components users must manage while maintaining efficient power delivery through the integrated design.
