Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stationary wireless charging coil is used, then the charging location is fixed and easy to implement, but the charging area is small and the user must carefully place the electronic device in the appropriate charging area
Solution Approach 1:
The patent applies the dynamics principle by making the charging coil movable rather than stationary. The charging coil can move along the usable surface of the charger panel to dynamically adjust its position and align with the receiving coil of the electronic device, thereby expanding the charging area and improving placement flexibility while maintaining ease of operation through automated positioning assistance
Solution Approach 2:
The patent implements feedback by using the near navigation system to detect the position and orientation of the electronic device relative to the charging coil, then providing notifications to guide the user in optimal placement. This feedback mechanism enables the system to adapt to different device positions while maintaining efficient charging alignment
2Adaptability or versatility
If traditional wired charging is used, then the charging location is limited by the length of the charging cable, but the charging connection is stable and reliable
Solution Approach 1:
The patent replaces the mechanical connection system (physical charging cable) with a wireless electromagnetic induction system. This substitution eliminates the physical cable length constraint that limits charging location flexibility, while maintaining reliable power transfer through the electromagnetic coupling between the movable transmitting coil and the receiving coil
3Adaptability or versatility
If the charger panel is made movable to expand charging locations, then the adaptability to various surfaces is improved, but the device complexity increases
Solution Approach 1:
The patent applies dynamics by enabling the charger panel to move between a storage position and a usable position. This dynamic positioning capability allows the panel to adapt to different mounting surfaces and usage scenarios while maintaining a compact form factor when not in use, balancing versatility with manageable system complexity
