Projector Lens Module with Expandable Hinge Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computers with projecting devices lack the ability to adjust the projection direction and collect the projection lens module, resulting in a fixed projection direction and an unneat housing design.
Innovation Solution
A computer with an expansible structure featuring multiple foldable and collectable joints allows the height and direction of the projection lens module to be adjusted, enabling automatic height change and collection within the computer housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projection lens module is fixed in the computer housing, then the structure is simple and stable, but the projection direction cannot be adjusted and the housing cannot maintain a neat outlook when the projector is not in use
Solution Approach 1:
The projection lens module is made dynamically adjustable through a hinge connection that allows it to rotate between a projection state (extending from the housing) and a retracted state (aligned with the housing surface). This dynamic structure enables projection direction adjustment while maintaining a neat housing appearance when not in use, resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If the projection lens module is extended for projection, then the projection function is available, but the computer housing appearance becomes unneat when the projector is not in use
Solution Approach 1:
The hinge connection enables the projection lens module to dynamically change its position - extending outward when projection is needed and retracting to be substantially coplanar with the housing surface when not in use. This dynamic repositioning resolves the contradiction between projection function availability and housing appearance.
3Adaptability or versatility
If a fixed projection structure is used, then the device is simple, but the projection height cannot be adjusted
Solution Approach 1:
The hinge connection creates a dynamic structure that allows the projection lens module to rotate to different angles, thereby adjusting the projection height and direction. This single hinge mechanism provides height adjustment capability while maintaining relatively simple structure, resolving the contradiction between adaptability and device complexity.

AI summary
A computer with a projecting device comprises: a base shell, disposed with a top face, the top face being disposed with an opening, the opening communicating an inner part of the base shell; an expansible structure, comprising a first unit, a second unit and a third unit, in which first bottom end of the first unit is pivotally coupled to the base shell through at least one first pivot unit, a second bottom of the second unit is pivotally coupled to the first unit through at least one second pivot unit and the third unit is pivotally coupled to the second unit through a pivot structure; a first face of the third unit is coupled to a projection lens module to allow a height of the projection lens module to be changed and a projection direction thereof to be adjusted.
