Tool-Free Wearable Housing Locking Structure for Strap Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional smart watch straps require specialized tools for detachment and installation due to their small and intricate spring bar design, making operation inconvenient.
Innovation Solution
A locking structure comprising a first structural body, a second structural body, a pressing member, and a clamped member, allowing for detachable connection and disconnection without the need for specialized tools, through the use of a key with a pressing member and clamped member that engage and disengage with a locking portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional spring bar connection is used, then the watch strap can be connected stably with the watch body, but specialized tools are required for detachment and installation making operation inconvenient
Solution Approach 1:
The locking structure enables the connection components to perform their own locking and unlocking operations without external tools. The first structural body and second structural body automatically engage through their respective mounting portions, with the connection assembly facilitating self-contained attachment and detachment operations.
Solution Approach 2:
The connection system is divided into distinct modular components: a first structural body, a second structural body, and a separate connection assembly. This segmentation allows each component to be optimized independently and facilitates tool-free operation by distributing functional responsibilities across separate elements.
2Volume of moving object
If a traditional spring bar design is used, then the connection structure is compact, but the small and intricate structure requires specialized tools for operation
Solution Approach 1:
The locking mechanism utilizes multi-directional movement and spatial arrangement of components. The connection assembly incorporates elements that move in different dimensions during engagement and disengagement, allowing compact sizing while maintaining tool-free operability through clever spatial design.
3Ease of operation
If a locking structure with multiple components is used, then tool-free operation is achieved, but the device complexity increases
Solution Approach 1:
The connection assembly integrates multiple functional elements into a unified component that works in coordination with the first and second structural bodies. By merging the locking and unlocking functions into the connection assembly itself, the overall system complexity is managed while maintaining tool-free operation capability.

AI summary
Provided are a locking structure, a housing assembly, and an electronic device. The locking structure includes first and second structural bodies, a pressing member, and a clamped member. The first structural body is provided with first and second mounting portions. The second structural body includes a locking portion. The pressing member is movably provided at the first mounting portion. The clamped member is movably provided at the second mounting portion, and can be engaged with the locking portion. In mounting the second structural body to the first structural body, the clamped member is driven by the locking portion to move, and is restored so as to be engaged with the locking portion. In detaching the second structural body from the first structural body, the pressing member is pressed by an external force to drive the clamped member to move so as to be disengaged from the locking portion.
