Wire Restraining Rib Structure for Knocking Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with sound-generating components experience unwanted knocking sounds due to vibrations causing internal components to collide, affecting sound quality and potentially damaging components.
Innovation Solution
An electronic device design featuring a housing with a first and second restraining holder and a protruding rib structure that supports wires between the holders, reducing collisions by maintaining a distance between the wires and the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wires are loosely arranged inside the electronic device, then ease of assembly is improved, but wire collisions with housing during vibration increase causing knocking sounds
Solution Approach 1:
The patent introduces a wire fixing component as an intermediary element between the wire and the housing. This component includes a fixing body with a wire receiving groove that accommodates the wire, and a buffer member that provides cushioning. The intermediary structure prevents direct contact between the wire and housing, eliminating knocking sounds while maintaining ease of assembly.
Solution Approach 2:
The buffer member is pre-installed on the wire fixing component to provide cushioning before any vibration or collision occurs. This beforehand cushioning ensures that when vibrations happen during sound generation, the wire is already protected by the buffer member, preventing knocking sounds and potential damage.
2Object-affected harmful factors
If wires are fixed tightly to prevent collisions, then knocking sounds are reduced, but device complexity increases
Solution Approach 1:
The wire fixing component merges multiple functions into a single integrated structure: the fixing body provides mechanical support and positioning, the wire receiving groove guides and secures the wire, and the buffer member provides vibration damping. This merging approach reduces overall device complexity compared to using separate components for each function.
Solution Approach 2:
The wire fixing component serves multiple purposes simultaneously: it acts as a structural support, a wire guide, a vibration damper, and a protective element. This multi-functionality reduces the need for additional specialized components, thereby simplifying the overall device structure while effectively preventing knocking sounds.
3Reliability
If buffer member softness is increased to reduce collisions, then wire protection is improved, but space requirements increase
Solution Approach 1:
The buffer member is designed with localized cushioning properties only where needed - specifically at the positions where the wire may contact the housing during vibration. This local quality approach provides effective wire protection while minimizing the overall volume occupied by the buffer member, as it does not require uniform cushioning throughout the entire structure.
