Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wired charging device is used to provide electric energy for the GPS module, then the charging connection is stable and reliable, but the placement position of the base station is limited and cannot be moved freely
Solution Approach 1:
The base station is equipped with a solar panel that enables it to generate its own electric energy through photovoltaic conversion. This self-powered design eliminates the need for external wired charging devices, allowing the base station to be placed anywhere with sunlight access while maintaining reliable operation through autonomous energy generation and storage in an integrated battery
2Loss of energy
If the solar panel is fixed at a specific angle, then the structure is simple and stable, but the energy conversion efficiency cannot be optimized for different sunlight conditions
Solution Approach 1:
The solar panel is mounted on an adjustable support structure that allows its inclination angle to be modified. This dynamic adjustment capability enables the solar panel to optimize its orientation toward the sun throughout the day or season, maximizing photovoltaic energy conversion efficiency while adapting to changing environmental conditions
Solution Approach 2:
The inclination angle of the solar panel can be changed to different fixed positions, allowing optimization of energy reception based on seasonal variations in sunlight angle. This parameter adjustment enables the system to maintain high energy conversion efficiency across different times of the year

AI summary
A GPS positioning stake (1, 2) of the present invention includes a supporting pole (10), a base (20), an adjustment board (30), and an angle adjusting device (40). The base (20) is connected with the supporting pole (10), and has a GPS positioning module (24) and a rotation axle (23). The adjustment board (30) has an axle sleeving portion (323) pivotably connected with the rotation axle (23), and a solar panel (314). The solar panel (314) provides electric energy for the operation of the GPS positioning module (24). The angle adjusting device (40) includes a first gear (42), a second gear (44, 44a), an elastic member (50), and an operation member (51, 54). The first gear (42) is fixedly sleeved onto the rotation axle (23). The second gear (44, 44a) is sleeved onto the rotation axle (23) and located in the axle sleeving portion (323). When the operation member (51, 54) locks, the second gear (44, 44a) is engaged with the first gear (42) to disable the adjustment board (30) from rotation relative to the rotation axle (23). When the operation member (51, 54) unlocks, the second gear (44, 44a) is separated from the first gear (42) to enable the adjustment board (30) to drive the second gear (44, 44a) to rotate relative to the rotation axle (23) so that the light receiving angle of the solar panel (314) is adjustable for better energy conversion efficiency of the solar panel (314).
