Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional 3D holographic projection equipment is used, then 3D imaging quality is improved, but device portability deteriorates
Solution Approach 1:
The device is divided into two main segments: a fixed base unit containing the imaging element (square-based pyramid) and a movable holder that can be adjusted to different positions. This segmentation allows the system to maintain high 3D imaging quality through the fixed imaging element while improving portability by making the holder movable and adjustable, enabling the device to be compact when not in use.
Solution Approach 2:
The holder is designed to be movable along the X-axis with adjustable positioning, transforming a static structure into a dynamic one. This dynamic design allows the holder to be moved to different positions (first position for normal use, second position for portability) and fixed at each position, thereby resolving the contradiction between maintaining imaging quality and improving portability.
2Stability of the object's composition
If fixed-size projection equipment is used, then imaging stability is improved, but adaptability to different device sizes deteriorates
Solution Approach 1:
The holder's movable design along the X-axis enables the system to adapt to different handheld electronic device sizes by adjusting the holder's position. When the holder is at the first position, stable imaging is achieved; when moved to the second position, the device becomes more compact. The elastic element provides dynamic adjustment capability while maintaining stability during operation.
Solution Approach 2:
The system changes the positional parameter of the holder along the X-axis to accommodate different device sizes. By adjusting the holder's position between the first and second positions, the device can adapt to various handheld electronic device dimensions while maintaining stable 3D imaging performance through the fixed imaging element.
3Manufacturing precision
If expensive projection equipment is used, then 3D projection capability is improved, but cost-effectiveness deteriorates
Solution Approach 1:
Instead of using expensive traditional projection equipment, the patent employs a square-based pyramid imaging element that works with the projection capability of common handheld electronic devices. This copying approach uses the existing projection capability of smartphones or tablets in conjunction with the imaging element to achieve 3D holographic projection, significantly reducing costs while maintaining 3D projection capability.
Solution Approach 2:
The patent replaces expensive, complex projection equipment with a simple, inexpensive square-based pyramid imaging element that can be manufactured at low cost. This imaging element works with the built-in projection capabilities of everyday handheld devices, eliminating the need for costly specialized projection equipment while maintaining effective 3D projection functionality.
