Electronic Device Cover With Breakable Optical Track
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device covers lack a reliable mechanism to detect deterioration or damage, which can lead to unintended electrical connections and potential safety hazards.
Innovation Solution
A cover design featuring a support body with a through-passage and an optical element, where electrically-conductive connection leads are attached to form a breakable line that interrupts power supply if the cover or optical element deteriorates, incorporating internal and external uncovered portions and intermediate sections through the support body, with electrical link bumps providing both structural support and electrical connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a cover with optical element is used in an electronic device, then light transmission and device functionality are improved, but the risk of unintended electrical connections and safety hazards increases upon deterioration or damage
Solution Approach 1:
The patent implements a breakable electrical connection line that is pre-configured to interrupt power supply upon cover or optical element damage. The electrical connection leads are rigidly attached with internal uncovered portions that can break when the cover deteriorates, proactively preventing safety hazards before they occur.
Solution Approach 2:
The patent introduces an intermediary detection mechanism where the breakable electrical connection line acts as a mediator between the cover structure and the power supply system. When the cover or optical element deteriorates, the intermediary electrical connection breaks, signaling the deterioration and cutting power to prevent hazards.
2Stability of the object's composition
If electrical connection leads are made rigid and attached through the support body, then structural stability and electrical connectivity are improved, but the complexity of the electrical connection system increases
Solution Approach 1:
The patent merges the structural support function with the electrical connection function by integrating the electrical connection leads into the support body structure. The leads are rigidly attached and pass through the support body, combining mechanical support and electrical connectivity in a single integrated design rather than separate systems.
3Reliability
If the electrical connection line is made breakable for safety detection, then safety and reliability are improved, but the risk of unintended electrical connections during normal operation increases
Solution Approach 1:
The patent applies local quality by making only specific portions of the electrical connection leads breakable (the internal uncovered portions within the support body) while keeping other portions stable and protected. The breakable sections are strategically located to detect cover deterioration, while the external and terminal portions maintain stable connectivity during normal operation.

AI summary
A cover for an electronic device includes a support body having a through-passage. An optical element which allows light to pass is mounted on said support body in a position extending across the through-passage. A surface of the optical element includes an electrically-conducting track configured as a security detection element. At least two electrical connection leads are rigidly attached to the support body and include first uncovered portions internal to the support body and electrically connected to spaced apart locations on the electrically-conducting track. The at least two electrical connection leads further including second uncovered portions external to said support body. The cover is mounted on a support plate carrying an electronic chip situated in the through-passage at a distance from the optical element.
