Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an external micro projector is added to a smartphone, then projection functionality is achieved, but the smartphone becomes thicker and more cumbersome
Solution Approach 1:
The projection system is divided into two separate components: a micro projector unit and a smartphone. The micro projector contains the projection lens, light source, and optical components, while the smartphone provides the display and control interface. This segmentation allows the smartphone to remain thin while still achieving projection functionality through magnetic attachment of the external projector.
2Ease of operation
If conventional projectors are made portable, then mobility is improved, but the device becomes bulky and unsuitable for carrying
Solution Approach 1:
The micro projector is designed to nest magnetically onto the smartphone, creating a compact integrated unit when needed. The projector unit is small enough to be carried separately or attached to the smartphone, eliminating the need for bulky conventional projectors while maintaining portability.
3Ease of operation
If a magnetic adhesion device is used to attach the projector to the smartphone, then connection convenience is improved, but the attachment strength may be insufficient
Solution Approach 1:
The magnetic adhesion system combines multiple magnetic blocks within the projector unit that collectively attach to a magnetic adhesion device in the smartphone. This distributed magnetic arrangement provides sufficient attachment strength while maintaining easy on and off functionality. The magnetic force is distributed across multiple contact points, ensuring secure attachment during use.
