Earphone Headband Connection Structure for Reduced Joint Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies result in relatively large dimensions of the components at the junction between the headband assembly and the connecting assembly, which are not effectively minimized, thereby reducing the dimensions of the components at the junction between the headband assembly and the connecting assembly, which are not effectively minimized, thereby reducing the dimensions of the components at the junction between the headband assembly and the connecting assembly, which are not effectively minimized, thereby reducing the dimensions of the components at the junction between the headband assembly and the connecting assembly, which are not effectively minimized, thereby increasing the dimensions of the earphones.
Innovation Solution
The earphone design incorporates a telescoping assembly with a locking mechanism that locks the first and the second limiting portions, which are connected by a telescoping member, and a locking mechanism that locks the first housing and the plugging portion along the telescoping direction, using a locking member to fix the first housing and the plugging portion relative to each other, and limiting the movement of the second housing in the telescoping direction, thereby reducing the thickness of the second housing and facilitating miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix the headband assembly and the connecting assembly, then connection strength is ensured, but the dimensions of components at the junction become relatively large
Solution Approach 1:
The connecting assembly is divided into a first connecting component and a second connecting component that can be assembled together. The first connecting component includes a first connecting portion to be connected to the headband assembly, and the second connecting component includes a second connecting portion to be connected to the speaker assembly. This segmentation allows for optimized dimensions at the junction without compromising connection strength.
Solution Approach 2:
The first connecting component and the second connecting component are nested or closely integrated to form a compact junction structure. By nesting these components, the overall dimension at the junction between the headband assembly and the connecting assembly is reduced while maintaining the necessary connection strength through the interlocking design of the components.
2Length of stationary object
If the dimension of components at the junction is reduced, then the earphones become more compact, but the connection strength may be compromised
Solution Approach 1:
The first connecting component and the second connecting component are designed with pre-formed connection structures that ensure adequate connection strength before final assembly. The connection structures include positioning features and engagement mechanisms that are prepared in advance, allowing for strong connections even in the compact junction design.
Solution Approach 2:
The connecting components are designed to utilize material properties and structural compositing to achieve high strength-to-size ratio. By optimizing the material selection and structural composition of the connecting components, the junction can maintain connection strength while occupying minimal space.
