Display Device Adjustable Module Shared Fastening Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in miniaturization due to the need for separate and fixed spaces for height adjusting devices, which complicates design, increases cost, and hinders effective volume reduction and maintenance.
Innovation Solution
A display device design featuring an upper and lower case with shared fastening holes for both fastening units and adjustable modules, allowing for compact structure, reduced material usage, and simplified assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate fixed spaces are reserved in the body for height adjusting devices, then the height adjustment function is achieved, but the device volume increases and miniaturization is limited
Solution Approach 1:
The patent combines the fastening function and height adjustment function into a single integrated structure. The fastening unit incorporates both a fastening portion (screw thread) and an adjustable portion (adjustable module with through hole) that share the same mounting space, eliminating the need for separate fixed spaces for each function.
Solution Approach 2:
The fastening unit is designed as a multi-functional component that simultaneously performs fastening (securing the adjustable module to the body) and height adjustment (allowing the projection unit to be adjusted vertically). This universal design reduces the overall device volume by consolidating multiple functions into one structure.
2Measurement precision
If multiple height adjusting devices are provided for precise projection angle adjustment, then the adjustment precision is improved, but the device complexity and volume increase
Solution Approach 1:
The patent merges multiple adjustment functions into a single adjustable module. Instead of providing separate height adjusting devices for each projection unit, the design allows multiple projection units to share common fastening and adjustment mechanisms, reducing device complexity while maintaining adjustment precision.
3Ease of manufacture
If the body and height adjusting device are designed separately and then assembled, then the manufacturing flexibility is improved, but the disassembly and maintenance difficulty increases
Solution Approach 1:
The patent segments the display device into modular components (body, projection units, adjustable modules) that can be independently manufactured and then assembled through the fastening units. This segmentation maintains manufacturing flexibility while enabling easy disassembly and maintenance, as each module can be accessed and serviced independently through the integrated fastening structure.

AI summary
A display device is provided. The display device has an upper case, a lower case, at least one fastening unit and at least one adjustable module. The upper case and the lower case respectively have at least one first fasten hole and at least one second fasten hole. The second fasten hole coaxially communicates with the first fasten hole. Through the second fasten hole, the unit is fixed in the first fasten hole to fasten the upper case and the lower case together. The adjustable module has an adjustable unit with a through hole penetrating therethrough. Furthermore, the adjustable unit is partially disposed in the second fasten hole. By disposing the adjustable unit and the fastening unit within the second fasten hole, the display device could be made more compact and the overall cost can be decreased.
