Rear Housing Mounting Structure for Screwless Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and disassembly of display devices, such as liquid crystal televisions and cellular phones, are inefficient due to the need for screwing and unscrewing the rear housing and backplane, which prolongs the process and reduces efficiency.
Innovation Solution
A mounting structure for the rear housing of a display device, featuring engaging beams and hooks that securely fix the backplane and rear housing without requiring screws, allowing for quick assembly by applying force directly to either component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screwing and unscrewing is used to fix the rear housing and backplane, then the connection strength is improved, but the assembly and disassembly efficiency deteriorates
Solution Approach 1:
The engaging structure is divided into multiple engaging beams and engaging hooks that can independently engage and disengage. Each engaging beam includes an engaging portion and a limiting portion, allowing the structure to be segmented into functional units that facilitate quick assembly while maintaining connection strength through distributed engagement points
Solution Approach 2:
The engaging structure utilizes elastic deformation of the engaging beams to enable dynamic engagement and disengagement. The limiting portion restricts the engaging portion's movement range, allowing the structure to transition between engaged and disengaged states through controlled elastic deformation, enabling quick assembly without screws while maintaining firm connection
2Loss of time
If a simple engaging structure is used to improve assembly efficiency, then the assembly time is reduced, but the connection reliability deteriorates
Solution Approach 1:
The engaging structure is pre-configured with limiting portions that define the engagement path and movement range before assembly occurs. This preliminary design ensures that when assembly takes place, the engaging beams automatically follow the correct engagement path and achieve reliable connection without requiring complex alignment procedures or additional fastening steps
Solution Approach 2:
The limiting portion acts as an intermediary element that mediates between the engaging portion and the engaging hook. It controls the engagement process by restricting movement range and guiding the engaging portion into proper position, ensuring reliable connection while keeping the assembly process simple and quick
