Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical button is used for human-machine interaction, then the interaction interface is fixed and simple to implement, but the volume is large and interaction efficiency is low
Solution Approach 1:
The patent replaces the mechanical physical button system with an optical touch control system. The touch control interface is projected onto a surface, allowing users to interact by touching the projected area. This substitution eliminates the need for physical buttons, significantly reducing volume while improving interaction efficiency through a larger, more flexible touch interface.
Solution Approach 2:
The patent creates a virtual copy of the control interface by projecting the touch control pattern onto a surface. Instead of requiring physical buttons, the system projects a visual representation of the control interface that users can interact with by touching the projected area. This copying approach maintains full functionality while eliminating the volume constraints of physical buttons.
2Adaptability or versatility
If separate elements are used to generate the source image and touchscreen, then the functions are clearly separated, but the overall space and cost increase
Solution Approach 1:
The patent makes the imaging module universal by enabling it to perform multiple functions: generating both the source image and the touch control interface. The same imaging module that displays the main content also projects the touch control patterns, eliminating the need for a separate touch projection module. This multi-functionality approach maintains functional versatility while significantly reducing overall space requirements.
Solution Approach 2:
The patent merges the source image generation function and the touch control interface generation function into a single imaging module. Both functions share the same light source and imaging components, consolidating what would traditionally be separate systems into one integrated unit. This merging reduces the number of components, decreases overall volume, and lowers system cost while maintaining both functionalities.
