Rotating Watchband Clamping Mechanism for Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing watchband attachment mechanism is not convenient for users, as elastic pins are pointy and thin, making it difficult to attach and detach the watchband from the watchcase.
Innovation Solution
A wearable device with a watchcase featuring a mounting slot and a key slot, where a clamping part with a rotating mechanism and stop block is used to securely attach the watchband by rotating the watchband, allowing the stop block to move into and out of the rotating part, and be clamped in the key slot, facilitating easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If elastic pins are used to connect the watchband to the watchcase, then the connection is simple, but the attachment process is inconvenient due to the pointy and thin structure
Solution Approach 1:
The clamping part is designed to rotate relative to the watchcase around the length direction of the strap-shaped body, transforming the static connection into a dynamic one that allows easy insertion and securing through rotational movement
Solution Approach 2:
A stop block is introduced as an intermediary element that engages with the mounting slot to prevent the clamping part from dislodging, providing a reliable stopping position during the attachment process
2Ease of operation
If a rotating mechanism with stop block is added to the clamping part, then the attachment convenience is improved, but the device complexity increases
Solution Approach 1:
The rotating mechanism and stop block are merged into a single integrated clamping part structure, combining multiple functions (clamping, rotating, stopping) into one component rather than using separate parts
Solution Approach 2:
The clamping part is designed to rotate and clamp automatically when the watchband is inserted into the mounting slot, with the stop block engaging with the mounting slot to provide self-locking functionality without requiring additional actuators

AI summary
A wearable device may include a watchcase defining a mounting slot and a key slot communicating with each other and a watchband. The watchband may include a strap-shaped body; and a clamping part connected to one end of the strap-shaped body and including a rotating part and a stop block arranged in the rotating part; the stop block is capable of moving out of or back into the rotating part; when the stop block moves into the rotating part, the clamping part is configured to be inserted into the mounting slot; after the clamping part is inserted into the mounting slot, the clamping part is configured to be rotated relative to the watchcase by rotating the watchband, and the stop block is configured to move out of the rotating part and is clamped in the key slot, such that the watchband is attached on the watchcase.
