Rollable Laser TV Screen Lifting Mechanism Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser television systems face issues with displacement, insufficient depth distance, and inadequate adjustable height, particularly in integrated machines where the screen installation requires on-site drilling and lacks adjustable height support.
Innovation Solution
A rollable and hidden laser television integrated machine is designed with a translation structure, a sound transmission mesh plate for heat dissipation, and a screen lifting mechanism using connecting rod and gear structures to achieve adjustable height and accurate motion, eliminating the need for on-site screen installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the laser television is placed directly on the table, then the structure is simple, but the device is easily displaced and requires deep distance in the direction of depth
Solution Approach 1:
The patent combines the laser television with a television cabinet into an integrated machine, merging the projection device with its supporting structure. This integration eliminates displacement issues while providing sufficient depth distance for proper projection, resolving the contradiction between structural simplicity and stability.
2Reliability
If the screen is installed separately and fixed to the wall, then the screen position is stable, but secondary site drilling is required for installation
Solution Approach 1:
The screen is integrated with the television cabinet as a unified structure, eliminating the need for separate wall installation and drilling. The screen becomes part of the cabinet assembly, maintaining position stability while simplifying installation to a single-step process.
3Reliability
If a translation structure is used to hide the laser television inside a box, then collision displacement issues are solved, but the device complexity increases
Solution Approach 1:
Instead of adding a separate translation structure, the laser television is integrated directly into the television cabinet structure. The cabinet itself serves as the housing and positioning structure, preventing displacement without requiring additional translation mechanisms.
4Ease of manufacture
If the screen lifting device is not integrated with the laser television, then the installation is simple, but the support strength is insufficient in the height direction
Solution Approach 1:
The screen lifting device is integrated with the television cabinet structure, allowing the cabinet to provide structural support for screen lifting operations. This integration maintains installation simplicity while significantly improving support strength in the height direction through the cabinet's rigid framework.
Applied Scientific Principles

Function Achieved in This Case
The solution provides a compact, user-friendly laser television system with adjustable height and accurate screen positioning, addressing the issues of displacement, depth distance, and installation complexity, while ensuring efficient heat dissipation.
Implementation Method 1
a sound transmission mesh plate is arranged in the front area of the laser television, which not only ensures the sound transmission of the laser television but also solves the problem of heat dissipation
Implementation Method 2
a sound transmission mesh plate is arranged in the front area of the laser television, which not only ensures the sound transmission of the laser television but also solves the problem of heat dissipation
Implementation Method 3
The rollable screen is controlled by two sets of motors. One set of motors controls the screen rising and lowering, and another set of motors controls the screen rolling
Implementation Method 4
a set of motors controls the screen rising and lowering, and the screen storage is realized by a preload spring
Implementation Method 5
The multi-link reinforcement design and the gear transmission are employed to ensure accurate transmission and accurate movement of the television screen
