Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional LEDs are installed at two sides of a heat-dissipating device in the same direction, then the structure is simple and easy to manufacture, but the light produced by the LEDs cannot match with the reflecting angles of the reflecting surface, reducing lighting efficiency
Solution Approach 1:
The patent applies the dynamics principle by making the LED mounting plate rotatable relative to the heat-dissipating device. This allows the LEDs to be adjusted to different angles and positions, enabling optimal alignment between the light beams and the reflecting surface. The rotatable mounting plate provides dynamic adjustability, transforming the static fixed-position LED installation into a flexible system that can be optimized for maximum lighting efficiency while maintaining ease of manufacture through a simple rotational mechanism.
2Device complexity
If the strongest light produced by LEDs is not directed onto the reflecting surface, then the LED structure is simple, but the amount of light reflected by the reflecting surface is reduced, lowering lighting efficiency
Solution Approach 1:
The patent applies the preliminary action principle by pre-configuring the rotatable mounting plate with adjustment mechanisms that allow the LEDs to be positioned and angled correctly before operation. The mounting plate is designed with preset angular positions or marking indicators that guide the alignment process, ensuring that the strongest light from each LED is directed precisely onto the reflecting surface. This preliminary setup eliminates the need for complex real-time adjustment mechanisms while achieving optimal lighting efficiency.
3Ease of manufacture
If conventional LED car lamps use LEDs positioned to emit light at fixed angles, then the manufacturing process is simple, but the light produced cannot be fully utilized, increasing power consumption
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotatable mounting plate that allows the LEDs to be adjusted to optimal angles for light reflection. This dynamic adjustment capability enables the system to maximize light utilization efficiency without requiring complex electronic control systems. The mechanical rotational adjustment is simple to manufacture and operate, yet it significantly improves the proportion of LED light that is effectively reflected and utilized, thereby reducing wasted energy and lowering overall power consumption requirements.
