Cantilevered Locking Mechanism for Repairable Display Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic device designs face challenges in manufacturing due to the close proximity of internal components, leading to issues such as high display failure rates when disassembled and the need for time-costly manual mechanisms for disassembly.
Innovation Solution
A locking mechanism featuring a chassis with a cantilevered plate that moves between a locked and unlocked position, allowing for easy detachment and reattachment of components without adhesives, using a magnetic attraction or external object to bend the plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If adhesive retention solutions are used to attach display screen to chassis, then the device achieves a low-profile design, but display failure rates increase when disassembled
Solution Approach 1:
The locking mechanism is divided into separate components: a locking member with locking arms that can independently engage with the display screen, and a chassis with corresponding receiving structures. This segmentation allows the display to be securely attached during operation while enabling clean separation during disassembly without adhesive failure.
Solution Approach 2:
The locking arms are designed to be movable between engaged and disengaged states. During normal operation, the locking arms maintain a locked position securing the display. During disassembly, the locking arms can be actuated to release the display screen, transforming the static adhesive bond into a dynamic mechanical lock that can be controlled.
2Reliability
If manual mechanisms are used for disassembly, then display failure rates are reduced, but repair time and cost increase
Solution Approach 1:
The locking mechanism includes self-aligning features where the locking arms automatically engage with the display screen's locking structures when components are brought together. The mechanism also includes self-latching features that maintain the locked state without continuous force, allowing quick release when actuated and reducing the skill level and time required for repair.
3Length of stationary object
If internal components are positioned closer together to reduce device size, then device dimensions decrease, but manufacturing design challenges increase
Solution Approach 1:
The locking mechanism components are designed to nest within each other and within the device housing. The locking arms fold against the chassis when not in use, and the entire locking mechanism integrates into the existing device structure without requiring additional external space, enabling close component positioning while maintaining manufacturability.

AI summary
Locking mechanisms and separable, repairable (e.g., electronic) devices having locking mechanisms are described herein. In one example, a locking mechanism includes a chassis having a base, a first side wall extending from a surface of the base, and a second side wall extending from the surface of the base. A cavity is provided in a volume formed by the first side wall, the second side wall, and the surface of the base, wherein the cavity is configured to receive a mating component of the device. The locking mechanism also includes a cantilevered plate having a first end and a second, opposite end, wherein the cantilevered plate is attached to the first side wall of the chassis at or adjacent to the first end, and wherein the second end of the cantilevered plate is positioned with the cavity.
