Adjustable Traction Wing Control Bar via Pivoting Fixing Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for traction wings in kite surfing lack adjustability in bar length, which can limit user flexibility and performance, as a longer bar reduces turning effort but may not suit all riding styles or kite sizes.
Innovation Solution
A control bar with pivotally connected fixing arms that allow for adjustable effective control bar lengths by pivoting between defined positions, enabling the bar to be set to different lengths for varying control and maneuverability needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a long control bar is used, then turning effort is reduced and turning speed is improved, but adaptability to different riding styles and kite sizes is worsened
Solution Approach 1:
The control bar incorporates articulated fixing arms that can pivot between multiple positions, allowing the effective length of the control bar to be dynamically adjusted. This enables the bar to transition from a fixed-length structure to an adjustable-length structure, resolving the contradiction by providing both long and short configurations to match different riding styles and kite sizes.
Solution Approach 2:
The invention changes the parameter of control bar length from a fixed value to an adjustable value. By providing multiple fixed positions for the articulating arms, the system allows users to select different effective lengths based on their specific needs, thereby adapting the ease of operation to different riding styles and kite sizes.
2Adaptability or versatility
If a short control bar is used, then adaptability to different kite sizes and tricks is improved, but turning effort and user input requirement increase
Solution Approach 1:
The articulated fixing arms enable the control bar to dynamically adjust its effective length, allowing users to switch between short and long configurations. This dynamic adjustment capability ensures that the control bar can be optimized for specific tricks or kite sizes while maintaining ease of operation when needed.
Solution Approach 2:
By allowing the control bar length parameter to be changed between multiple fixed positions, the system enables users to select shorter lengths for improved adaptability to specific kite sizes and tricks, while accepting increased turning effort only when such adaptability is required.
3Device complexity
If a fixed length control bar is used, then device complexity is reduced, but adaptability to different user needs is worsened
Solution Approach 1:
The control bar is segmented into a fixed central bar portion and articulated fixing arm portions that can pivot independently. This segmentation allows the fixing arms to be positioned at different angles, creating multiple effective lengths while keeping the central bar structure simple and fixed.
Solution Approach 2:
The articulated fixing arms introduce dynamic adjustability to an otherwise simple fixed structure. By allowing the arms to pivot between defined positions, the system adds adaptability without significantly complicating the overall device, as the arms follow simple rotational paths around fixed pivot points.

AI summary
A control system for a traction wing includes a control bar having first and second ends. A first fixing arm is connected to each end of the bar. Each fixing arm has a fixing point for attachment of a respective wing control line. At least one of the fixing arms is an articulated arm that is pivotally connected to its end of the bar and is pivotable between a first position defining a first effective control bar length and a second position defining a second effective control bar length.
