Solution Overview

Problem

Existing kitesurf release systems are complex, expensive to manufacture, and have a large height, making it difficult for users to quickly reduce kite power, especially for short practitioners, and can hinder safety line passage, leading to incomplete sail unveiling in emergencies.

Innovation Solution

A hooking system with a central body composed of two parts assembled by a fixing means, allowing natural release and reducing manufacturing costs, featuring a fastener with an envelope and elastic return mechanism for quick attachment and detachment, and a line breaker integrated within the central body to minimize height and facilitate rope management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single-piece central body is used in existing release systems, then the structure is simpler in assembly, but the manufacturing cost increases due to expensive molds with drawers and the height increases making it difficult for users to quickly reduce kite power

Engineering Contradiction:
Improvemanufacturing costVSAvoidheight of release system
Core Design Contradiction:
Ease of manufactureVSLength of moving object

Solution Approach 1:

The central body is divided into two separate parts: a first part and a second part. The first part contains the release mechanism while the second part contains the line untwister. These two parts are assembled together using fixing means (screws or bayonet mounting) to form the complete central body. This segmentation allows each part to be manufactured separately using simpler, less expensive molds without requiring complex drawers, while also reducing the overall height of the assembled release system.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a single-piece central body with superimposed line untwister is used, then the structure is integrated, but the total height increases and manufacturing requires expensive molds with drawers

Engineering Contradiction:
Improveintegration of componentsVSAvoidmold complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The central body is segmented into two functional parts: the first part housing the release mechanism and the second part housing the line untwister. This segmentation allows each component to be manufactured using simpler molds without requiring complex drawer mechanisms, while the two parts are then assembled together to achieve the integrated functionality of a single-piece design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first part and second part are merged through assembly using fixing means (screws or bayonet mounting) to create the complete central body. This merging achieves the functional integration of the release mechanism and line untwister in a single assembled unit, while avoiding the manufacturing complexity of producing them as a single molded piece.

Inventive Principle:
Principle #5Merging (Combining)

3Volume of moving object

If the central body has a narrow central hole, then the structure is more compact, but the safety line passage becomes difficult and sail de-winding is incomplete in emergencies

Engineering Contradiction:
Improvecentral body volumeVSAvoidsafety line passage
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The central body is divided into two parts with strategically positioned openings. The first part has a first opening that accommodates the safety line, while the second part has a second opening that allows the safety line to pass through the line untwister. This segmented opening arrangement provides adequate passage space for the safety line without requiring an excessively large central hole, maintaining compact dimensions while ensuring complete sail de-winding capability.

Inventive Principle:
Principle #1Segmentation

4Length of moving object

If the release system height is reduced, then user mobility and power reduction speed improve, but the assembly becomes more difficult and manufacturing precision requirements increase

Engineering Contradiction:
Improverelease system heightVSAvoidassembly precision
Core Design Contradiction:
Length of moving objectVSManufacturing precision

Solution Approach 1:

The release system is segmented into two modular parts that can be manufactured with standard tolerances and then assembled together. The fixing means (screws or bayonet mounting) provide robust connection that compensates for minor dimensional variations, allowing the parts to be manufactured with conventional precision rather than requiring extremely tight tolerances that would be necessary for a single-piece design of the same reduced height.

Inventive Principle:
Principle #1Segmentation
