Display Chassis Disassembly Mechanism for Portable Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display chassis designs in portable information handling systems face challenges when it is necessary to remove the display component after assembly, as the adhesive attachment method makes it difficult to disassemble without damaging the components.
Innovation Solution
A display chassis design featuring a display component attachment assembly with a disassembly component that can be actuated to release the display component from the rear display cover, allowing for easy removal by pulling it away from the hinge assembly after accessing and actuating the disassembly components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adhesive attachment method is used to attach display component to rear display cover, then assembly is simplified and manufacturing efficiency is improved, but disassembly becomes difficult and may cause component damage
Solution Approach 1:
The attachment assembly is segmented into multiple functional components: adhesive attachment mechanism for bonding, and disassembly components (release mechanism, pulling mechanism, or cutting mechanism) that can be selectively activated. This segmentation allows the system to provide both strong assembly bonding and controlled disassembly capabilities without compromising either function.
Solution Approach 2:
The attachment assembly transitions from a static adhesive bond to a dynamic system that can change its bonding state. The disassembly components enable the adhesive bond to be selectively activated or deactivated, allowing the display component to be firmly attached during normal operation but easily removed when disassembly is required through actuation of the release mechanism.
2Stability of the object's composition
If display component is firmly attached to rear display cover, then structural stability is improved, but component removal requires damage to the attachment structure
Solution Approach 1:
The disassembly components act as intermediary elements between the adhesive attachment mechanism and the display component. These intermediaries (release mechanisms, pulling mechanisms, or cutting mechanisms) provide a controlled interface for breaking the adhesive bond without applying excessive force that would damage the display component or rear display cover, thereby enabling damage-free disassembly while maintaining structural stability during operation.
3Ease of manufacture
If adhesive attachment method is used, then manufacturing complexity is reduced, but maintenance and upgrade capabilities are limited
Solution Approach 1:
The attachment assembly is designed with multi-functionality, combining both adhesive attachment capabilities and integrated disassembly mechanisms within a single component system. This universal design allows the same assembly structure to serve both manufacturing (easy assembly) and maintenance/upgrade (easy disassembly) purposes, thereby improving adaptability without significantly increasing manufacturing complexity.
