Enclosed Drawstring Clasp with Dual-Actuator Spring Gripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional drawstring clasps lack resilience and expose parts that can catch hair or other objects, and they require time to tie and untie, while also allowing drawstrings to retract into garments.
Innovation Solution
A drawstring clasp with a wholly enclosed clutch mechanism featuring two opposing springs and unique two-button activation, which provides additional holding power and prevents hair or objects from getting caught, and includes aesthetically pleasing designs such as geometric shapes and sound modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional knots are used to secure drawstrings, then the drawstring can be secured when the desired opening is reached, but additional time is required to tie and untie
Solution Approach 1:
The clasp is divided into distinct functional components: a body portion with a clutch mechanism, and separate actuator buttons. This segmentation allows the gripping function to operate automatically while the release function is triggered separately, enabling quick operation without sacrificing security.
Solution Approach 2:
The clutch mechanism automatically grips the drawstring upon insertion without requiring manual tying or complex manipulation. The spring-loaded actuators self-engage to secure the drawstring, and a simple button press automatically releases it, making the system self-servicing and eliminating time-consuming manual knotting.
2Ease of operation
If traditional clasps or toggles are used, then the drawstring can be adjusted quickly, but they have an exposed portion that can easily allow hair or other items to be caught
Solution Approach 1:
The clutch mechanism is fully enclosed within the body portion of the clasp, with the gripping surfaces contained inside the housing. The actuators are recessed into the body, creating a smooth outer surface with no protruding elements that could catch hair or other objects, while the functional components remain nested inside performing their gripping function.
3Device complexity
If traditional clasps are used, then the structure is simple, but they fail to offer adequate resilience and allow drawstrings to retract into the garment
Solution Approach 1:
The clutch mechanism incorporates spring-loaded actuators that provide dynamic, resilient gripping force. The springs continuously apply pressure to maintain engagement with the drawstring, automatically compensating for any movement or retraction attempts. This dynamic mechanism transforms a simple static clasp into an active, self-adjusting gripping system that prevents drawstring retraction while maintaining relatively simple overall structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution offers secure and easy adjustment of drawstrings with enhanced gripping power, preventing hair or objects from being caught and allowing for quick release, while maintaining aesthetic appeal and preventing drawstrings from retracting into garments.
Implementation Method 1
The biasing mechanisms can include springs that bias the actuating mechanisms outward from within the housing
Implementation Method 2
The actuating mechanisms can comprise inward facing teeth for gripping a drawstring
