Tool-less Traction Kite Chicken Loop Bayonet Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traction kite systems require tools for changing or replacing chicken loops, which is time-consuming and inconvenient, especially when different styles or materials are needed for various conditions or user preferences.
Innovation Solution
A traction kite anchoring device with a bayonet-style connection that allows tool-less engagement and disengagement of the chicken loop, using a first end that can be received and secured in a receptacle with a series of discrete translational and rotational movements, providing a secure interference fit without the need for additional fasteners or tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded fastener is used to secure the chicken loop to the anchor, then the connection is secure and reliable, but the replacement requires tools and time
Solution Approach 1:
The connection system is divided into separate components: a fixed receptacle on the anchor and a removable anchor element on the chicken loop. This segmentation allows the chicken loop to be quickly detached and replaced without tools, while the receptacle remains permanently secured to the anchor, maintaining connection reliability through precise geometric matching.
Solution Approach 2:
The connection transitions from a static threaded fastener to a dynamic bayonet-style mechanism that can be quickly engaged and disengaged. The anchor element features a slot that receives a projection on the receptacle, allowing rotational movement for engagement and disengagement, enabling tool-free replacement while maintaining secure connection during use.
2Ease of operation
If a tool-less connection mechanism is used, then the replacement is quick and convenient, but the connection security may be compromised
Solution Approach 1:
The bayonet-style connection uses curved or angled surfaces in the slot and projection geometry to ensure secure engagement. The rotational engagement path creates a self-locking effect where the geometry itself provides the securing force, eliminating the need for tools while maintaining connection security through precise curved surface matching.
Solution Approach 2:
The slot and projection are designed with asymmetric geometry that allows engagement in one direction but prevents disengagement without deliberate action. The slot is oriented and shaped to receive the projection at a specific angle, creating a secure locked position that cannot be accidentally released, thus ensuring connection security while enabling tool-free replacement.
