Display Switch Member Assembly for Precise Cabinet Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices suffer from aesthetic issues due to uneven gaps between the switch member and rear cabinet, increased manufacturing costs, and reduced work efficiency caused by the need for multiple screws and complex assembly procedures.
Innovation Solution
A display device design featuring a switch member fixedly coupled between the front and rear cabinets using a guide cylinder and annular protrusions, allowing precise positioning and alignment of the switch member without lateral pushing, reducing the number of screws required and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two screws are threaded clockwise to fix the brackets of the switch member, then the brackets are secured to the front cabinet, but the switch member is pushed by the screw heads and budged away from its original position to the right side, causing uneven gaps between the switch member main body and the recess of the rear cabinet
Solution Approach 1:
A positioning protrusion is provided on the front cabinet that fits into a positioning recess on the switch member main body. This intermediary positioning mechanism ensures that the switch member is accurately positioned before the brackets are fixed, preventing the switch member from being pushed away during the screwing process and ensuring even gaps with the rear cabinet recess.
2Strength
If three screws are used to fasten the rear cabinet and switch member to the front cabinet, then the assembly is securely fixed, but the manufacturing cost increases and the assembly process becomes more time-consuming
Solution Approach 1:
The positioning function and the fixing function are merged into a single integrated positioning protrusion structure on the front cabinet. This positioning protrusion not only locates the switch member accurately but also serves as one of the fixing points, thereby reducing the total number of screws needed from three to two while maintaining secure assembly.
3Reliability
If three screws are required for fastening the assembly, then secure fixation is achieved, but the number of parts increases and threading multiple screws reduces work efficiency
Solution Approach 1:
The positioning protrusion on the front cabinet combines multiple functions: it positions the switch member accurately, supports the weight of the switch member, and serves as one of the three fixing points. This merging of functions reduces the number of separate fastening parts needed while maintaining reliable and secure fixation of the assembly.

AI summary
A display device includes a display screen, a front cabinet, a rear cabinet and a switch member. The front cabinet has a pair of front supporting portions. Each of the front supporting portions has a threaded hole. The rear cabinet has a pair of rear supporting portions. Each of the rear supporting portions has a first through hole. The switch member is fixedly coupled between the front cabinet and the rear cabinet with screws and has a pair of brackets. Each of the brackets has a second through hole, and is sandwiched between each pair of the front supporting portion and the rear supporting portion. The screws are inserted through the first through holes of the rear supporting portions and the second through holes of the brackets and threaded into the threaded holes of the front supporting portions.
