Solution Overview

Problem

Existing electronic devices, such as in-ear hearing aids and headphones, face challenges in miniaturization and lightweight design due to their structural designs, which often result in large size and heavy weight.

Innovation Solution

A wearable device with a housing assembly and button assembly, featuring a movably connected operating button and pivot structure, allowing for reduced component configuration and efficient space utilization, facilitating miniaturization and lightweight design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional structural design with internal framework and external housing is used, then functional components can be assembled into unified structure, but device size and weight increase

Engineering Contradiction:
Improveassembly of functional componentsVSAvoiddevice weight
Core Design Contradiction:
Ease of manufactureVSWeight of moving object

Solution Approach 1:

The patent merges the internal framework and external housing into an integrated structure where the housing itself serves as the structural support. The operating button is directly integrated into the housing wall, eliminating the need for separate mounting brackets and internal framework components. This consolidation reduces the total number of parts and overall device weight while maintaining structural integrity and assembly ease.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If traditional structural design with internal framework and external housing is used, then functional components can be assembled into unified structure, but device volume increases

Engineering Contradiction:
Improveassembly of functional componentsVSAvoiddevice volume
Core Design Contradiction:
Ease of manufactureVSVolume of moving object

Solution Approach 1:

The operating button is nested directly within the housing wall structure, with the button cavity formed as an integral part of the housing. The pivot structure is embedded within the housing wall thickness, and the button shaft passes through the housing wall directly. This nesting approach eliminates the need for separate mounting structures and internal framework, significantly reducing device volume while maintaining ease of assembly.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Stability of the object's composition

If operating button is fixedly connected to housing, then structural stability is improved, but device cannot achieve miniaturization

Engineering Contradiction:
Improvestructural stabilityVSAvoiddevice volume
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The patent transitions from a fixed connection to a dynamic pivot connection, where the operating button rotates about a pivot axis formed within the housing wall. This dynamic connection provides sufficient structural stability for button operation while enabling compact integration within the housing thickness. The pivot structure maintains stable mechanical connection without requiring additional internal framework or increasing device volume.

Inventive Principle:
Principle #15Dynamics

4Ease of repair

If multiple separate components are used for button assembly, then ease of maintenance is improved, but device complexity increases

Engineering Contradiction:
Improvemaintenance of button assemblyVSAvoidcomponent configuration
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The button assembly is segmented into functionally independent elements: the operating button head, the button shaft, the pivot structure, and the limiting flange. Each segment can be independently manufactured and assembled. The button can be removed and replaced by detaching it from the pivot connection, while the pivot structure remains integrated with the housing. This segmentation provides ease of maintenance without requiring complex multi-component assemblies.

Inventive Principle:
Principle #1Segmentation
