Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If permanent illumination is used with button switching, then the lamp structure is simple, but energy is wasted due to inability to automatically switch off
Solution Approach 1:
The sensor switch enables the lamp to automatically detect user presence and switch on/off without manual intervention, making the system self-regulating and eliminating energy waste from permanent illumination while maintaining operational simplicity
Solution Approach 2:
The manual button switching mechanism is replaced with an automatic sensor-based control system that uses optical or motion sensing to determine when illumination is needed, substituting mechanical operation with automated detection and control
2Ease of operation
If fixed mounting is used, then the installation is simple, but the lamp is inconvenient to dismount for replacement
Solution Approach 1:
The mounting structure is divided into separable components (mounting base and adapter) that can be easily assembled and disassembled, allowing the lamp to be conveniently installed and removed without complex fixed mounting while maintaining installation simplicity
Solution Approach 2:
The mounting system transitions from a static fixed connection to a dynamic adjustable connection that allows easy assembly and disassembly through the separable mounting base and adapter components
3Adaptability or versatility
If fixed illumination direction is used, then the structure is stable, but the illumination direction cannot be adjusted according to demands
Solution Approach 1:
The LED light panel connection changes from a fixed rigid mounting to a pivotable adjustable connection, allowing the illumination direction to be dynamically adjusted to different angles while maintaining structural stability through the pivot connection mechanism
Solution Approach 2:
The LED light panel is given rotational freedom in a new dimension (angular adjustment), transforming the illumination from a single fixed direction to multiple adjustable directions within a 0-100 degree range

AI summary
The present application discloses a solar lamp, comprising a main frame, a solar panel, an LED light panel, a sensor switch and a mounting base. The solar panel is fixed to the main frame. The LED light panel is movably connected to the main frame, and forms an included angle of 0-100 degrees with respect to a plane where the main frame is located. The sensor switch is mounted on a bottom face of the main frame, and is opposite the ground. The mounting base is connected to the main frame, and is provided with an adapter. The lamp senses presence and absence of a user via the sensor switch so as to switch on or off lights, thereby realizing effects of power saving and automatic switch-on and switch-off; and the illumination direction of the LED light panel is adjustable.
