Watch Strap Coupler With Concealed Connecting Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watch straps are designed specifically for a particular watch main body, making it impossible to couple another strap to the same watch main body.
Innovation Solution
A strap design featuring a spring rod, a strap main body with decorative members coupled by a thread-like member, a coupler with a spring rod insertion hole, a fixing member insertion hole, and a connecting ring arrangement portion, allowing the strap to be easily coupled to a watch main body using a generic spring rod, while enabling easy removal and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strap is designed with a dedicated coupling structure for a specific watch main body, then the strap can be securely fixed to the watch, but another strap cannot be coupled to the same watch main body
Solution Approach 1:
The patent applies universality by designing the coupler with a standardized spring rod insertion hole that can accommodate generic spring rods used in various watch models. This allows the same strap to be coupled to different watch main bodies, achieving multi-functionality and interchangeability while maintaining secure fixation through the spring rod mechanism
2Ease of manufacture
If connecting rings are exposed on the strap, then the structure is simple and easy to assemble, but the design appears less elegant
Solution Approach 1:
The patent applies nesting by placing the connecting rings inside the coupler body, where they are hidden from external view. The connecting rings are positioned in a recessed area of the coupler, allowing them to perform their structural function of connecting the strap main body to the coupler while remaining concealed, thus maintaining design elegance without complicating the assembly process

AI summary
A strap of the present disclosure includes a spring rod that includes a shaft member, and a strap main body that includes a plurality of decorative members coupled to each other and a connecting ring coupled to an end portion of the plurality of decorative members. The strap further includes a coupler that includes a spring rod insertion hole through which the spring rod is inserted, a fixing member insertion hole, and a connecting ring arrangement portion in which the connecting ring is disposed and that can be coupled to a watch main body of a watch by the spring rod, and a fixing member that connects the strap main body and the coupler by being inserted through the fixing member insertion hole and the connecting ring.
