Wearable Device Strap Fastening Guide Recess System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable electronic devices with pin spring strap fastening structures face difficulties in accurately aligning the pin with the hole, leading to potential damage to the device or strap during the fastening process.
Innovation Solution
Incorporating a guide recess system in the fastening portion of the wearable electronic device, which includes spaced apart coupling portions with specific recesses to facilitate easy insertion and fixation of the strap's fastening structure, reducing the need for precise alignment and minimizing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pin spring structure is used for strap fastening, then the strap can be securely attached to the wearable device, but it becomes difficult for users to accurately align the pin with the hole and determine the exact recess position
Solution Approach 1:
The patent applies preliminary action by providing guide recesses that extend from the front surface toward the rear surface of the frame. These guide recesses pre-establish the correct insertion path and position for the pin, allowing users to simply insert the pin along the guided path without needing to manually align it with the hidden recess. The guide recess performs the alignment function in advance, making the fastening operation simple and accurate.
2Measurement precision
If users manually align the pin with the hole in the wearable device, then accurate positioning can be achieved, but the wearable device or fastening structure may be damaged during the process
Solution Approach 1:
The patent introduces guide recesses as an intermediary structure between the pin and the recess. Instead of directly inserting the pin into the recess (which risks damage), the guide recess serves as a protective intermediary that guides the pin along a safe path. The guide recess absorbs the alignment function and protects the frame and pin from damage during insertion, eliminating the need for users to manually align components that could be damaged.
3Reliability
If the fastening structure requires precise alignment, then secure attachment is achieved, but the fastening process becomes complex and time-consuming
Solution Approach 1:
The guide recesses perform the alignment function in advance by being pre-formed as integral parts of the frame structure. Users do not need to spend time manually aligning the pin with the recess or determining the exact insertion position, as the guide recess already establishes the correct path. This preliminary preparation of the guide structure significantly reduces the time required for fastening while maintaining secure attachment.
