Detachable Strap Uniting Tool for Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wearable devices often have integrated uniting tools that are not exchangeable, leading to limitations in design and functionality, as well as inconvenience in wearing due to the spinning of straps when using single or double uniting pins.
Innovation Solution
A detachable strap uniting device with a uniting tool featuring a guide and catching part, allowing for independent design and material choices, preventing strap spinning and enhancing wrist-wearing convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the uniting tool is integrally made and fixed to the strap, then the structure is simple, but the design flexibility and functionality are limited
Solution Approach 1:
The uniting tool is divided into a body portion and a separate uniting member that can be detached and exchanged. The strap has a uniting tool receiving structure that accommodates different uniting members, allowing the uniting tool to be segmented into interchangeable components rather than being an integral fixed structure.
Solution Approach 2:
The uniting tool transitions from a static integral structure to a dynamic interchangeable system. The uniting member can be detached from and reattached to the body portion, and different uniting members can be exchanged based on functional requirements, providing adaptability while maintaining structural simplicity through standardized receiving structures.
2Ease of operation
If the uniting tool has one uniting pin, then the wearing action is convenient, but the strap spins freely and does not fit well
Solution Approach 1:
The uniting member employs asymmetric guide protrusions that correspond to asymmetric guide grooves in the strap. This asymmetric design prevents the strap from spinning freely while maintaining ease of insertion, as the asymmetric features guide the strap into the correct orientation during the wearing action.
Solution Approach 2:
The uniting member integrates multiple functions into a single component: it provides the uniting pin function for convenience, includes guide protrusions for preventing spinning, and features a catching structure for secure attachment. This multi-functional design resolves the contradiction by combining elements that address both convenience and stability.
3Reliability
If the uniting tool has two uniting pins, then the strap fitting is improved, but the wearing action becomes inconvenient
Solution Approach 1:
Instead of using two symmetric uniting pins, the invention uses asymmetric guide protrusions on a single uniting member. This asymmetric design provides adequate strap fitting and spinning prevention while maintaining ease of operation, as the asymmetric features guide the strap into place during insertion rather than requiring precise alignment of multiple pins.
4Reliability
If the body and wearing part are integrated, then the wearable device is stable, but replacement and customization are impossible
Solution Approach 1:
The wearable device is segmented into a body portion and a separate uniting member that can be exchanged. The uniting tool receiving structure on the strap provides a standardized interface that maintains stable attachment while allowing different uniting members to be replaced, thus achieving both wearing stability and customization capability.
Solution Approach 2:
The uniting tool receiving structure serves as a universal interface that accommodates different types of uniting members. This universal design maintains the stability of the integrated system while enabling replacement and customization of the uniting member, allowing users to exchange components based on different needs without compromising wearing stability.
