Soundproofing Cover Hook Protrusion Anti-Disengagement Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soundproofing covers face reliability issues due to the tendency of hook portions to come off from hook protrusions, compromising the soundproofing effectiveness.
Innovation Solution
The soundproofing cover incorporates hook protrusions with a protrusion body, a first engaging protrusion protruding towards the tip of the hook portion, and a second engaging protrusion protruding opposite to the tip, which securely engage with the hook portion, preventing disengagement and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple hook portion and hook protrusion structure is used, then the device complexity is reduced, but the reliability deteriorates due to the tendency of the hook portion to come off from the hook protrusion
Solution Approach 1:
The hook protrusion is segmented into multiple functional parts: a protrusion body, a first engaging protrusion, and a second engaging protrusion. Each segment performs a specific function - the protrusion body provides the base structure, the first engaging protrusion prevents disengagement in one direction, and the second engaging protrusion prevents disengagement in the opposite direction. This segmentation allows the structure to achieve high reliability without excessive complexity.
Solution Approach 2:
The first and second engaging protrusions act as intermediary elements between the hook portion and the protrusion body. These intermediary structures facilitate secure engagement by providing additional contact points and mechanical interlocking features, preventing the hook portion from coming off while maintaining a relatively simple overall structure.
2Device complexity
If a single engaging protrusion is used, then the device complexity is minimized, but the reliability is insufficient as the hook portion can easily disengage
Solution Approach 1:
The engagement structure is divided into multiple functional segments - the protrusion body and two distinct engaging protrusions positioned at different locations. This segmentation creates multiple engagement points that work together to prevent disengagement, significantly improving reliability compared to a single engaging protrusion while keeping the structure relatively simple.
Solution Approach 2:
The first and second engaging protrusions are positioned at different locations along the extending direction of the hook portion, creating a multi-dimensional engagement system. This spatial arrangement ensures that the hook portion cannot disengage by moving in any single direction, as both engaging protrusions must be simultaneously overcome, thereby enhancing reliability.

AI summary
A soundproofing cover includes a cover body, a hook portion a hook hole, and a hook protrusion protruding from an outer surface of the cover body. The cover body is maintained in a closed state with the hook portion hooked on the hook protrusion. The hook protrusion includes a protrusion body protruding from the outer surface of the cover body, a first engaging protrusion protruding from a distal end of the protrusion body toward a tip end of the hook portion in an extending direction of the hook portion with the hook portion hooked on the hook protrusion, and a second engaging protrusion protruding from the distal end of the protrusion body in a direction opposite to the tip end of the hook portion in the extending direction with the hook portion hooked on the hook protrusion.
