Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the solar panel is fixed in a single orientation, then the structure is simple and stable, but the light collection efficiency decreases when sun angles change
Solution Approach 1:
The solar panel is made adjustable through a pivot assembly with rotation and deflection mechanisms, allowing it to dynamically change orientation according to sun angles. The pivot assembly includes a rotating part that enables axial rotation and a pivot part that enables upward or downward deflection, transforming the static solar panel into a dynamic structure that adapts to changing environmental conditions while maintaining structural stability through controlled mechanical joints.
2Device complexity
If the LED lamp head is fixed in one direction, then the structural design is simple, but the illumination range is limited
Solution Approach 1:
The LED lamp head is integrated with the pivot assembly, allowing it to rotate and deflect along with the solar panel. The pivot rods and hook part enable the lamp head to change orientation dynamically, providing versatile illumination directions while maintaining a relatively simple overall structure through the shared pivot mechanism.
3Adaptability or versatility
If multiple fixing methods are integrated, then the adaptability to different installation environments is improved, but the device complexity increases
Solution Approach 1:
The positioning stand is designed with multi-functionality, incorporating a rod body with a top end that can be fixed to walls or columns, a bottom end that can be plugged into the ground, and a hook part that enables hanging installation. This universal positioning device integrates multiple fixing methods into a single structure, providing versatile installation options while avoiding the need for separate positioning devices for each installation type.
