Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed charging pad is used for wireless power transmission, then power can be transmitted to electronic devices, but the electronic devices are restricted in movement during charging and multiple devices require multiple fixed pads
Solution Approach 1:
The patent applies the dynamics principle by making the wireless power transmission module movable rather than fixed. The module can dynamically reposition itself between different charging locations on the charging pad, allowing a single module to serve multiple devices at different positions. This resolves the contradiction by enabling movement freedom for devices while avoiding the need for multiple fixed pads.
2Productivity
If multiple fixed charging pads are deployed to charge multiple devices, then all devices can be charged simultaneously, but the system complexity and infrastructure requirements increase proportionally
Solution Approach 1:
The patent applies universality by designing a single wireless power transmission module that can perform multiple charging functions at different locations. The module moves to different positions on the charging pad to charge various devices, making one module universal for multiple charging tasks. This resolves the contradiction by enabling simultaneous charging of multiple devices without requiring proportional increases in pad infrastructure.
Solution Approach 2:
The movable wireless power transmission module dynamically repositions itself to serve multiple devices, allowing a single module to replace what would traditionally require multiple fixed pads. This dynamic capability enables the system to scale charging capacity without linearly increasing infrastructure complexity.
3Adaptability or versatility
If wireless power transmission module is moved to different locations, then multiple devices can be charged with a single pad, but the control and positioning complexity increases
Solution Approach 1:
The wireless power transmission module incorporates autonomous positioning capabilities through sensors and processors that enable it to automatically detect device locations and navigate to appropriate charging positions without complex external control systems. This self-service approach resolves the contradiction by providing location flexibility while minimizing control system complexity.
Solution Approach 2:
The patent replaces complex mechanical positioning systems with sensor-based detection and automated control. Touch sensors and communication interfaces detect device positions, and the processor automatically controls the module's movement, substituting sophisticated mechanical control with simpler sensor-processor actuator systems.
