Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the illumination indicating apparatus continuously projects the illumination light beam to the ground, then the illumination effect is maintained, but the automobile battery consumes electric power continuously until exhausted
Solution Approach 1:
The projection device switches between different projection modes (dynamic projection image mode and illumination light beam mode) based on the state of the switchable mechanism. When the switchable mechanism is in the first state, the device projects dynamic projection images; when in the second state, it projects illumination light beams. This periodic switching resolves the contradiction by providing illumination only when needed while enabling diverse projection effects at other times, thus reducing continuous power consumption.
2Device complexity
If the illumination indicating apparatus projects a fixed illumination pattern, then the structure is simple, but it cannot provide diversified projection effects
Solution Approach 1:
The projection device incorporates a dynamic projection image capability that can display changing patterns and images on the ground. The projection pattern switching circuit enables the device to switch between fixed illumination patterns and dynamic projection images based on the state of the switchable mechanism. This dynamic capability resolves the contradiction by providing both simple fixed patterns for basic illumination and complex dynamic images for diversified effects.
Solution Approach 2:
The projection device is designed to perform multiple functions: it can project fixed illumination light beams for basic lighting, project dynamic projection images for diverse visual effects, and switch between these modes based on the switchable mechanism's state. This multi-functionality resolves the contradiction by making a single device capable of both simple illumination and complex projection effects, eliminating the need for separate devices for each function.
3Adaptability or versatility
If the projection device projects dynamic projection images, then diversified projection effects are provided, but power consumption increases
Solution Approach 1:
The projection device uses the state of the switchable mechanism to control when dynamic projection images are displayed versus when fixed illumination beams are projected. By switching between these modes periodically based on external conditions (the switchable mechanism state), the device provides diversified projection effects only when appropriate while conserving power during other periods, thus resolving the contradiction between versatility and power consumption.
