Wearable Housing Assembly for Miniaturized Split Movement Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as in-ear or ear-hanging hearing aids and headphones, face challenges in miniaturization and lightweight design due to their structural designs that result in large size and heavy weight.
Innovation Solution
A wearable device with a housing assembly comprising a first and second housing, connected to enclose an accommodating cavity, and a movement assembly dispersedly connected to both housings, utilizing polyimide (PI) structures for the housings and incorporating a fixing and positioning system to facilitate miniaturization and lightweight design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional structural design with internal framework and functional components is used, then device functionality is achieved, but device size and weight increase
Solution Approach 1:
The device is divided into a housing assembly and a movement assembly that can be separately connected. The movement assembly includes first and second assemblies that can be dispersedly connected to the housing, allowing independent optimization of each module's size and reducing overall device complexity while maintaining functionality.
Solution Approach 2:
The movement assembly is disposed within or connected to the housing assembly in a nested configuration. The first and second assemblies are integrated with the housing structure, eliminating the need for separate internal frameworks and reducing overall device size while maintaining structural integrity.
2Weight of moving object
If traditional structural design with internal framework and functional components is used, then device functionality is achieved, but device weight increases
Solution Approach 1:
By segmenting the device into housing assembly and movement assembly with separate first and second assemblies, each component can be optimized for minimal weight. The分散 connection approach eliminates redundant structural elements and internal frameworks that would add unnecessary weight while maintaining device functionality.
3Strength
If housing components are connected with multiple fixing and positioning structures, then structural integrity is improved, but assembly complexity increases
Solution Approach 1:
Multiple fixing structures (fixing pin, support arm) and positioning structures (positioning protrusion, positioning groove) are merged into integrated components. The fixing pin and support arm form a unified fixing structure, while the positioning protrusion and groove provide both positioning and fixing functions simultaneously, reducing the number of separate parts and simplifying assembly.
Solution Approach 2:
The fixing and positioning structures are designed to serve multiple functions. The positioning protrusion not only locates the movement assembly but also guides assembly. The fixing pin provides both mechanical fixation and structural support. This multi-functionality reduces the number of components needed while maintaining structural integrity.

AI summary
A wearable device includes a housing assembly and a movement assembly. The housing assembly includes a first housing and a second housing, the first housing being connected to the second housing to form an accommodating cavity between the first housing and the second housing; the movement assembly being provided in the accommodating cavity and including a first assembly and a second assembly in electrical connection with the first assembly, the first assembly being connected to the first housing, and the second assembly being connected to the second housing. By dispersedly connecting the movement assembly to the first housing and the second housing, the housing assembly may be designated as a structural mounting carrier of the movement assembly, not only reducing the number of related connecting parts but also making full use of the housing structure and space, which is conducive to the miniaturization and lightweight design of the device.
