Snap-Fit Frame Assembly for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screw locking methods for assembling display devices often damage the outer frame and compromise its appearance, leading to structural weaknesses and complex assembly processes.
Innovation Solution
A frame assembly design featuring a mounting member, sliding member, top cover, and bottom cover with engaging mechanisms, such as protruding lugs and hooks, that allow for secure fixation without screws, enabling easier assembly and a more robust, aesthetically pleasing wedge-shaped structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw locking method is used to fix the outer frame, then the assembly is secure, but the outer frame structure is damaged and appearance is affected
Solution Approach 1:
The patent removes the screw locking mechanism from the assembly system and replaces it with a snap-fit structure. The outer frame includes engaging protrusions that mate with corresponding recesses in the display device, eliminating the need for screws and avoiding damage to the frame structure while maintaining secure assembly.
Solution Approach 2:
The patent replaces the mechanical screw locking system with a elastic snap-fit mechanism. The outer frame incorporates elastic engaging structures that provide secure fixation through elastic deformation and mechanical interlocking, substituting the traditional screw-threaded mechanical connection with a more gentle elastic engagement that preserves frame integrity.
2Reliability
If screw locking method is used, then the assembly is secure, but the assembly process becomes complex
Solution Approach 1:
The patent extracts the screw locking components (screws, threaded holes, locking mechanisms) from the assembly system and replaces them with integrated snap-fit structures. This simplification reduces the number of parts and assembly steps while maintaining secure fixation through elastic engaging protrusions and recesses.
Solution Approach 2:
The patent merges the fixing function and the structural support function into a single snap-fit engaging structure. The outer frame simultaneously provides structural support and secure fixation through its integrated engaging protrusions and recesses, eliminating the need for separate screw fastening systems and reducing overall assembly complexity.
3Reliability
If multiple screws are used to fix the outer frame, then the assembly is secure, but the number of parts increases
Solution Approach 1:
The patent combines multiple fixing functions into a single integrated snap-fit structure. The outer frame incorporates engaging protrusions and recesses that simultaneously provide multiple fixation points and structural support, replacing what would traditionally require multiple separate screws and associated hardware, thereby reducing the total part count while maintaining assembly security.
Solution Approach 2:
The outer frame is designed with multi-functional engaging structures that simultaneously serve as structural supports, alignment guides, and secure fixation elements. The snap-fit engaging protrusions and recesses perform multiple functions in a single integrated component, eliminating the need for separate fasteners and reducing the overall number of parts required.
