Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table stand is connected to a domestic electricity supply system, then the electric motor can be powered reliably, but the placement of the table stand is restricted by the location of power sockets
Solution Approach 1:
The patent extracts the power supply system from the domestic electricity grid and replaces it with a self-contained solar panel and battery system. The solar panel is positioned on the table surface to capture sunlight, converting solar energy to electrical energy that charges the battery, which then powers the electric motor for height adjustment. This extraction eliminates the need for external power sockets and enables flexible placement anywhere with sunlight access.
2Adaptability or versatility
If a solar panel is used to power the electric motor directly, then placement flexibility is improved, but the motor may not receive sufficient power during operation
Solution Approach 1:
The patent implements preliminary action by charging the battery during periods when the motor is not operating. The solar panel continuously charges the battery whenever sunlight is available, storing energy in advance. When the height adjustment function is needed, the pre-charged battery provides sufficient power to the motor, ensuring reliable operation without requiring the motor to be directly connected to the solar panel during operation.
3Reliability
If the battery stores power for later use, then power availability is improved, but the device complexity increases
Solution Approach 1:
The patent applies multi-functionality by designing the battery to serve dual purposes: it powers the electric motor for height adjustment and simultaneously provides power to additional devices through integrated power outlets. This universal power supply approach means the same battery that ensures reliable motor operation also charges smartphones, tablets, or other portable devices, thereby reducing overall system complexity rather than increasing it.
