Jump Rope Quick Release with Spring-Loaded Pawl
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick release connections for jump ropes require simultaneous pressure on two points to open, making them inconvenient for easy and quick exchange of ropes/cables with different weights and diameters.
Innovation Solution
A quick release connection design featuring a housing with protruding sidewalls, a spring-loaded toothed pawl, and an asymmetrical trapezoidal profile for interlocking teeth, allowing for easy one-finger operation and secure locking of cable adapters with different properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional quick release connection with multiple locking levers is used, then secure connection is achieved, but ease of operation deteriorates because simultaneous pressure on two points is required to open
Solution Approach 1:
The locking mechanism is segmented into a pawl that can be independently actuated, allowing the user to engage or disengage the locking function by operating a single element rather than coordinating multiple points simultaneously
Solution Approach 2:
The pawl is extracted as a separate, movable component from the housing, enabling independent control of the locking function through a single pulling motion on the pawl itself, rather than requiring simultaneous pressure on multiple fixed points
2Ease of operation
If a simple connection mechanism is used, then ease of operation is improved, but reliability deteriorates because secure locking may not be achieved
Solution Approach 1:
The tooth profile of the linear rack is designed with asymmetry, featuring a first leg at a first angle and a second leg at a second angle, which creates a ratcheting effect that allows easy insertion but secure locking in the opposite direction
Solution Approach 2:
The spring acts as an intermediary element that automatically engages the pawl with the teeth of the linear rack, providing reliable locking without requiring complex manual coordination from the user
3Adaptability or versatility
If the quick release connection is designed for universal compatibility, then adaptability is improved, but device complexity increases due to multiple components
Solution Approach 1:
The housing is designed with a standardized opening that can receive different types of cable adapters, and the locking mechanism uses a universal pawl-tooth interface that works with various cable configurations, enabling one quick release connection to serve multiple cable types
Solution Approach 2:
The cable adapter is designed to be inserted into and nested within the housing, with the linear rack fitting into the holding channel formed by sidewalls, creating a compact nested structure that reduces overall complexity while maintaining versatility

AI summary
Quick release connection for jump rope facilitating exchanging of cables with different weights and diameters on jump rope handles. The quick release connection for jump rope comprises the housing of quick release connection with a locking part attached. The locking part comprises a toothed pawl loaded with a spring engaging with the teeth of the linear rack attached to the cable adapter. The housing of the quick release connection has protruding first and second sidewalls, defining a holding channel including at least one guide rail, for receiving the cable adapter. The linear rack has at least one protruding part that is configured to move into at least one guide rail featured on at least one of the sidewalls of the holding channel. The possible insertion of the cable adapter into the holding channel is only in the longitudinal, reciprocating position.
