Wedge-Shaped Tablet Projection Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices lack the ability to adjust projection height and focal length using their structure design, leading to limitations in usability and functionality, especially in devices like tablets where space and component placement are critical.
Innovation Solution
The electronic device features a wedge-shaped body with a rotatable support and a projection component, allowing for adjustable height and focal length adjustments through structural design, including a cavity for the projection component and a transmission structure connected to the projection lens, enabling the adjustment of the focal length by moving the adjustment structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a projection apparatus is integrated in a tablet computer with uniform thickness, then the device is compact and portable, but the projection height cannot be adjusted without additional external objects
Solution Approach 1:
The tablet computer body is designed with a wedge shape where the thickness varies from one end to the other, creating a dynamic thickness profile rather than a uniform static thickness. This allows the projection height to be adjusted by changing the orientation of the tablet, eliminating the need for additional external objects while maintaining compactness
2Adaptability or versatility
If the tablet computer body has uniform thickness, then the manufacturing is simple, but the projection height adjustment is limited
Solution Approach 1:
The tablet computer body adopts an asymmetric wedge shape with varying thickness from one end to the other. This asymmetric design provides different projection heights at different orientations while remaining manufacturable through standard molding processes, thus achieving adaptability without significantly complicating manufacturing
3Ease of operation
If there is no focusing button for projection, then the device structure is simpler, but the focal length adjustment requires moving the entire tablet forward or backward
Solution Approach 1:
A focusing button is integrated into the wedge-shaped body that can be pressed to dynamically adjust the focal length of the projection lens. This provides fine-tuned focal adjustment capability without requiring movement of the entire tablet, improving ease of operation while maintaining structural simplicity
