Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple infrared light sources are added for accurate optical positioning, then positioning accuracy is improved, but manufacturing cost increases and aesthetic design is compromised
Solution Approach 1:
The patent applies multi-functionality by making existing single-function light sources (status indicator lights, sound holes, heat-dissipation vents) serve dual purposes: their original functions plus serving as infrared light sources for optical positioning. This eliminates the need for separate dedicated infrared light sources while achieving accurate positioning.
