Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power supply is used to avoid wired connections in movable components, then ease of operation and design flexibility are improved, but power supply efficiency deteriorates due to distance and angle variations
Solution Approach 1:
The patent applies dynamics by making the power supplying portion movable along with the movable body, allowing the power supply system to adapt dynamically to changing positions and maintain efficient power transfer throughout the range of motion
Solution Approach 2:
The patent uses an amplifier circuit as an intermediary to boost the output voltage of the power supply, enabling effective wireless power transmission over longer distances and varying angles between the power supplying and receiving portions
2Adaptability or versatility
If distance and angle between power components are increased to allow movement, then adaptability is improved, but power supply efficiency worsens due to reduced coupling
Solution Approach 1:
The power supplying portion is configured to move dynamically with the movable body, maintaining optimal positioning relative to the power receiving portion throughout the range of motion, thus preserving power supply efficiency while achieving adaptability
Solution Approach 2:
The amplifier circuit serves as a mediator that compensates for the reduced coupling effect caused by increased distance and angle variations, maintaining sufficient power transmission efficiency across diverse positional configurations
3Loss of energy
If direct current resonance method is used for wireless power supply, then power supply efficiency is improved over conventional methods, but device complexity increases due to resonance circuit requirements
Solution Approach 1:
The patent merges the power supply circuit and amplifier circuit into an integrated system, combining multiple functions into unified components to reduce overall device complexity while maintaining the benefits of direct current resonance power supply
Solution Approach 2:
The power supply system is designed with multi-functionality, where the same resonance circuit and amplifier components serve multiple purposes including power conversion, voltage boosting, and adaptive power transmission across varying conditions

AI summary
A storage device includes a storage body having an opening and a lid for selectively opening and closing the opening of the storage body. The storage body has a light emitter and a power receiving portion connected to the light emitter. The lid has a power supplying portion, which is configured to supply power to the power receiving portion by the direct current resonance method. The light emitter emits light to interior of the storage body at a first luminance when the opening is closed by the lid. When the lid opens the opening so that the distance between the power receiving portion and the power supplying portion is reduced, the light emitter changes the luminance to a second luminance, which is different from the first luminance.
