Projector Supporting Piece Pivots to Adjust Angle and Trigger Lens Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projector designs with adjustable feet increase the overall thickness, hindering the development of super-thin projectors and complicating packaging.
Innovation Solution
A projector design featuring a supporting piece that pivots between two positions to adjust the projector's angle and trigger a projection lens opening or power control device, allowing for adjustable projection angles while reducing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable feet are fixed at the bottom of the projector for angle adjustment, then the projection angle can be adjusted, but the overall thickness of the projector increases
Solution Approach 1:
The patent combines the angle adjustment function with the lens cover function into a single integrated component. The lens cover is designed to rotate between covering the projection lens and extending outward to adjust the projection angle, eliminating the need for separate adjustable feet and reducing overall projector thickness.
Solution Approach 2:
The lens cover serves multiple functions: it protects the projection lens when closed, and acts as an angle adjustment mechanism when rotated outward. This multi-functional design replaces traditional single-function adjustable feet, achieving both lens protection and angle adjustment while maintaining a thin profile.
2Adaptability or versatility
If adjustable feet are fixed at the bottom of the projector, then the projection angle can be adjusted, but the packaged size of the projector increases
Solution Approach 1:
The patent combines the angle adjustment function with the lens cover function into a single integrated component. The lens cover is designed to rotate between covering the projection lens and extending outward to adjust the projection angle, eliminating the need for separate adjustable feet and reducing overall projector thickness.
3Adaptability or versatility
If a pivot mechanism is used for the supporting piece, then the projection angle can be freely adjusted, but the device complexity increases
Solution Approach 1:
The patent combines the angle adjustment function with the lens cover function into a single integrated component. The lens cover is designed to rotate between covering the projection lens and extending outward to adjust the projection angle, eliminating the need for separate adjustable feet and reducing overall projector thickness.

AI summary
A projector, comprising a housing (100) and a machine body provided inside the housing (100). A supporting piece (200) is connected to the housing (100) via a connection mechanism, and the supporting piece (200) can be converted between a first position and a second position under the limiting action of the connection mechanism. The supporting piece (200) is attached to a surface of the housing (100) at the first position, and a projection element is triggered at the same time to enable the machine body to be in a first working state. The supporting piece (200) departs from the surface of the housing (100) at the second position and drives the housing (100) to change a projection elevation thereof with respect to a horizontal plane, and the projection element is triggered at the same time to enable the machine body to be in a second working state, thereby controlling the working states of the machine body on the premise of free adjustment of a projection angle.
