Wearable Coupling Member Locking Structure for Secure Band Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices face challenges in maintaining a stable worn state while allowing easy replacement of coupling members to express user personality, as existing designs either detach too easily or are difficult to remove and replace.
Innovation Solution
A coupling member design that allows easy attachment and detachment from the housing while maintaining a stable worn state, featuring a combination of protrusions, recesses, and elastic components to secure the device to the user's body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the coupling member is made to be easily attached and detached, then the ease of operation is improved, but the stability of the worn state deteriorates
Solution Approach 1:
The coupling member is divided into multiple functional segments: a band member for wearing, a locking member for securing, and a protrusion-recess mechanism for attachment. This segmentation allows each part to perform its specific function optimally - the band member provides flexibility for easy attachment while the locking member ensures stability during wear.
Solution Approach 2:
The recess formed in the housing acts as an intermediary element between the coupling member and the housing. The protrusion on the coupling member engages with this recess, creating a stable connection during wear while still allowing for controlled detachment when needed.
2Stability of the object's composition
If the coupling member is rigidly mounted to maintain stable worn state, then the stability of worn state is improved, but the ease of operation deteriorates
Solution Approach 1:
The coupling member incorporates dynamic elements that allow it to transition between different states. The locking member can be actively engaged to provide rigid mounting stability during wear, and actively disengaged to allow easy replacement. This dynamic capability resolves the contradiction between stable worn state and ease of replacement.
3Adaptability or versatility
If the coupling member is made detachable to allow replacement for expressing personality, then the adaptability is improved, but the reliability deteriorates
Solution Approach 1:
The attachment and detachment functions are extracted as separate, controlled operations. The coupling member design allows the band member to be easily detached for replacement while the locking member provides reliable securing when attached. This extraction of functions enables both adaptability for personal expression and reliability for secure attachment.

AI summary
A coupling member that is attachable to/detachable from a housing of an electronic device while making the housing wearable on a user's body, and an electronic device including the coupling member is provided. The electronic device includes a band member that is configured to come in contact with a user's body portion, a slide member that is mounted on the band member, and is bound to a portion of the housing in a state where the coupling member is mounted on the housing, an opening that is formed in the slide member, a locking member that is disposed on the band member, and a locking protrusion that is formed on a locking member. The locking protrusion appears to the outside of the slide member through the opening according to the reciprocating of the locking member, and the coupling member is bound to the housing.
