Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple optics-lenses and motors are used to create moving image projections, then the image projection capability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple optics-lenses (first projection lens and second projection lens) with the LED light source into a single integrated housing structure. This merging approach allows the system to project multiple images simultaneously while reducing the overall device complexity compared to using separate projection devices. The optics-lenses are positioned at different locations within the housing to achieve different projection angles and surfaces.
Solution Approach 2:
The LED light source serves multiple functions: it provides illumination and simultaneously acts as the projection source for both the first and second optics-lenses. The single LED unit can project images onto multiple surfaces (wall and ceiling) through the integrated optics system, demonstrating multi-functionality that reduces the need for separate projection devices.
2Adaptability or versatility
If traditional projection methods are used, then image projection is achieved, but heat generation and signal interference occur
Solution Approach 1:
The patent utilizes the LED light source's inherent properties to serve dual purposes: illumination and projection. The LED naturally emits light that can be directed through the optics-lenses without requiring additional high-power projection bulbs, thereby avoiding the heat generation associated with traditional projection methods. The system is self-sufficient using the LED's own light output.
Solution Approach 2:
The patent replaces traditional mechanical projection systems (which use high-power bulbs and complex lens assemblies) with an LED-based optical system. This substitution eliminates the harmful heat and signal interference generated by conventional projection methods while maintaining the projection function through the integrated LED and optics-lenses configuration.
3Device complexity
If fixed angle projection is used, then simple structure is maintained, but viewing angle and adaptability are limited
Solution Approach 1:
The patent employs asymmetric positioning of the first and second optics-lenses within the housing, with each lens oriented at different angles relative to the LED light source. The first optics-lens is configured for wall projection while the second optics-lens is configured for ceiling projection, creating asymmetric projection angles that expand the viewing angle and adaptability without requiring complex adjustable mechanisms.
