Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Acoustic output apparatuses, such as headphones, face challenges in maintaining structural stability and reducing wire movement, which affects sound quality and product durability.
Innovation Solution
The acoustic output apparatus includes a speaker assembly and an ear hook assembly with a connecting part that features a wire clamping mechanism to secure lead wires, ensuring they are fixed in a radial direction and reducing movement during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lead wires are loosely connected in the accommodating space, then the device complexity is reduced, but the structural stability and reliability deteriorate due to wire movement and vibration
Solution Approach 1:
The patent introduces a wire clamping part as an intermediary component between the lead wires and the accommodating space. This clamping part secures the lead wires in a fixed position, preventing movement and vibration, while maintaining a relatively simple overall structure. The clamping part acts as a mediator that resolves the conflict between structural stability and device complexity.
2Reliability
If wire clamping parts are added to fix lead wires, then structural stability improves, but device complexity increases due to additional components
Solution Approach 1:
The patent combines the wire clamping function with the existing connecting part structure. The connecting part integrates both the function of electrical connection and wire fixation, eliminating the need for separate complex fixing mechanisms. This merging approach maintains connection stability while avoiding excessive increase in device complexity.
3Ease of manufacture
If lead wires are allowed to move freely, then ease of manufacture is improved, but sound quality deteriorates due to wire vibration during use
Solution Approach 1:
The patent implements preliminary fixation of the lead wires using the wire clamping part during the assembly process. By securing the wires in their final positions before the device is put into use, the structure prevents vibration and ensures sound quality. This preliminary action approach maintains ease of manufacture while preventing sound quality deterioration.
