Display Module Snap-Fit Assembly via Position Limiting Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing tolerances in display panels and assembly elements lead to misalignment and increased complexity in assembly, requiring multiple screwing steps or adhesives, which prolongs assembly time and increases costs.
Innovation Solution
A display module with a position limiting structure comprising a frame and a bracket, where the frame has protruding parts and position limiting structures that align with corresponding structures on the bracket to securely fix it without screws or adhesives, simplifying assembly and reducing the number of required elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw fastening is used to fix the frame and display panel, then the assembly can be securely fixed, but the assembly process becomes complex and time-consuming due to multiple screwing steps required to accommodate manufacturing tolerances
Solution Approach 1:
The patent removes the screw fastening mechanism from the assembly process and replaces it with a position limiting structure consisting of positioning protrusions and positioning grooves. This extraction of the fastening function eliminates the need for multiple screwing steps while maintaining secure fixation, directly resolving the contradiction between fixing reliability and assembly complexity
Solution Approach 2:
The position limiting structure acts as an intermediary mechanism between the frame and display panel. The positioning protrusions and grooves serve as mediating elements that automatically align and secure the components together, replacing the complex screw fastening process with a simple snap-fit assembly that accommodates manufacturing tolerances
2Device complexity
If adhesive is used to assemble the display panel, then the number of assembly elements is reduced, but the assembly time increases and the adhesive cannot be reused if errors occur
Solution Approach 1:
The patent extracts the adhesive material from the assembly process and replaces it with a mechanical position limiting structure. This allows for rapid assembly without the time-consuming application and curing processes required by adhesives, while also enabling disassembly and reuse if errors occur
Solution Approach 2:
The position limiting structure performs the assembly function automatically through the engagement of positioning protrusions and grooves, eliminating the need for external adhesive materials. The structure self-aligns and secures the components in place, reducing both assembly time and material requirements
3Reliability
If conventional fastening methods are used, then the display panel can be securely fixed, but the display module weight increases due to the additional fasteners and assembly elements
Solution Approach 1:
The patent removes the heavy screw fasteners and adhesive materials from the assembly and replaces them with an integrated position limiting structure that is part of the frame itself. This extraction of separate fastening elements significantly reduces the overall weight while maintaining secure fixation through the positioning protrusions and grooves

AI summary
A display module including a display panel, a frame and a bracket is provided. The frame surrounds the display panel and has a protruding part and a first position limiting structure. The bracket has a body with a second position limiting structure and a first protrusion, wherein the protruding part is aligned with the first protrusion when the first position limiting structure is engaged with the second position limiting structure to fix the bracket on the frame in a non-screw manner.
