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 design, which often results in large size and heavy weight.

Innovation Solution

A wearable device with a housing assembly and button assembly, featuring a movably connected operating button that protrudes through a button window, utilizing a pivot structure and limiting structures to facilitate rotation and input commands, and a decentralized movement assembly within a housing assembly to optimize space utilization and reduce component count.

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 capabilityVSAvoiddevice weight
Core Design Contradiction:
Ease of manufactureVSWeight of moving object

Solution Approach 1:

The patent merges the internal framework structure with the external housing by making the housing itself bear the structural support function. The housing assembly integrates both protective enclosure and structural framework roles, eliminating the need for separate internal framework components and reducing overall device weight while maintaining assembly capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing assembly is designed to serve multiple functions simultaneously: it provides protective enclosure, structural support, and mounting surface for functional components. This multi-functional design eliminates redundant structures and reduces device weight while maintaining ease of manufacture through standardized housing assembly processes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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 capabilityVSAvoiddevice volume
Core Design Contradiction:
Ease of manufactureVSVolume of moving object

Solution Approach 1:

The patent merges the internal framework structure with the external housing by making the housing itself bear the structural support function. The housing assembly integrates both protective enclosure and structural framework roles, eliminating the need for separate internal framework components and reducing overall device volume while maintaining assembly capability.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If operating button is fixed inside housing, then structure is simple, but user interaction capability is limited

Engineering Contradiction:
Improvebutton structure complexityVSAvoiduser interaction capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The operating button is designed with rotational movement capability through a pivot structure, transitioning from a static fixed position to a dynamic multi-position element. This allows the button to provide multiple interaction modes (pressing, rotating to different positions) while maintaining relatively simple structural implementation through the pivot mechanism.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The button assembly is segmented into movable button component and stationary housing component, connected through a pivot structure. This segmentation enables the button to rotate independently within the housing, providing enhanced user interaction capability while keeping the overall structure relatively simple and manageable.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If more components are added to achieve functionality, then device functionality improves, but device complexity increases

Engineering Contradiction:
Improvedevice functionalityVSAvoidcomponent count
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing assembly is designed to serve multiple functions simultaneously: it provides protective enclosure, structural support, and mounting surface for functional components. This multi-functional design eliminates redundant structures and reduces device weight while maintaining ease of manufacture through standardized housing assembly processes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A wearable device includes a housing assembly and a button assembly. The housing assembly includes a first housing provided with a housing space and a button window. The button assembly includes an operating button provided in the housing space. The operating button is movably connected to an inner wall of the first housing. At least a portion of the operating button protrudes out of the first housing through the button window. By movably connecting the operating button with the inner wall of the first housing, the housing assembly is directly designated as a mounting carrier for the button assembly without using other connecting parts. It's not only conducive to full utilization of the structural space of the housing assembly but also conducive to reducing the configuration number of components, thereby providing support for convenient and quick disassembly and maintenance, and realizing miniaturization and lightweight design of the device.
