Solution Overview

Problem

Existing wearable devices face challenges in efficiently and easily assembling and disassembling straps with electronic apparatuses, leading to complex and time-consuming processes.

Innovation Solution

A housing assembly with an engaging member in the mounting groove that moves to provide an avoidance space for the connector, restoring to engage with it at a predefined location for secure connection, allowing for simple and quick assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional connection structure is used between strap and electronic apparatus, then the connection is stable, but the assembly and disassembly process is complex and time-consuming

Engineering Contradiction:
Improveassembly and disassembly processVSAvoidconnection structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The engaging member is designed to be movable relative to the housing, transitioning between engaged and disengaged states. This dynamic mechanism allows the connector to be easily inserted and removed while maintaining stable connection during use, resolving the contradiction between ease of operation and connection stability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connection structure is divided into separate functional components: the engaging member, the housing, and the connector. This segmentation allows each component to perform its specific function independently, enabling simple assembly and disassembly operations while ensuring reliable connection when engaged

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the engaging member moves to provide avoidance space for connector insertion, then assembly is simplified, but the structure becomes more complex

Engineering Contradiction:
Improveconnector insertionVSAvoidengaging member mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The engaging member is designed to be movable relative to the housing, transitioning between engaged and disengaged states. This dynamic mechanism allows the connector to be easily inserted and removed while maintaining stable connection during use, resolving the contradiction between ease of operation and connection stability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The engaging member automatically engages with the connector when the connector is inserted to the predefined location, eliminating the need for manual intervention to secure the connection. This self-engaging feature simplifies the assembly process while maintaining connection reliability

Inventive Principle:
Principle #25Self-service
