Push-Button Assembly for Tool-Free Display Panel Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disassembly of display panels from supporting frames in electronic devices often results in structural damage due to excessive force, leading to deformation of bezels and variations in antenna performance.
Innovation Solution
A push-button assembly is integrated into the housing, featuring a tubular member with an actuator that applies an optimum force to disengage the display panel from the supporting frame without external tools, preventing damage and maintaining dielectric material integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual disassembly tools are used to separate the display panel from the supporting frame, then disassembly capability is achieved, but structural damage occurs due to excessive force
Solution Approach 1:
A push-button assembly acts as an intermediary mechanism between the user and the display panel. The push-button applies controlled force through a mechanical linkage to the retention structure, enabling disassembly without requiring external tools or excessive force that would damage the structure.
Solution Approach 2:
The push-button assembly is integrated into the device housing and provides self-contained disassembly functionality. The mechanism uses the device's own structural elements (housing, push-button, and retention structure) to achieve disassembly, eliminating the need for separate manual tools.
2Productivity
If excessive force is applied during disassembly, then the display panel can be separated from the supporting frame, but the bezel deforms and antenna performance varies
Solution Approach 1:
The push-button assembly changes the force application parameters by distributing force uniformly through a mechanical linkage system. This transforms the disassembly process from applying high concentrated force to applying controlled, distributed force through the push-button mechanism, preventing bezel deformation while maintaining disassembly efficiency.
3Ease of operation
If a push-button assembly is integrated into the housing, then safe disassembly is achieved without external tools, but device complexity increases
Solution Approach 1:
The push-button assembly serves multiple functions: it acts as both a user interface element for disassembly and as an integrated structural component of the housing. The mechanical linkage system performs both force transmission and structural support functions, reducing the need for separate components.

AI summary
Examples of display devices are described. In an example, a display device may comprise a display panel, a supporting frame to hold the display panel within a housing of the display device, and a push-button assembly. In an example, the push-button assembly comprises a tubular member having a first end and a second end. The first end is located on an external surface of the housing, while the second ends abuts a surface of the display panel. An actuator may be slidably disposed within the tubular member. Upon actuation, the actuator may slide outward of the second end to disengage the display panel from the supporting frame.
