Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing kiteboarding technologies lack a practical method for rapidly reducing the pulling power of a traction kite or immediately releasing the kiteboarder from the kite's pull, leading to dangerous situations such as death-loops and loss of control.

Innovation Solution

A hand-actuated bailout trigger and optional depower handle are integrated into the kite rigging, allowing the kiteboarder to immediately depower the kite or activate a bailout trigger to cease the kite's pull, enabling safe recovery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a kiter uses legacy quick release mounted below the control bar, then the quick release can be manipulated to release from the kite, but the kiter must take at least one hand off the control bar to operate it, reducing control capability

Engineering Contradiction:

Improvequick release operationVSAvoidloss of kite control

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent combines the quick release function and depower handle into a single integrated control mechanism mounted on the control bar. This merging allows the kiter to operate both functions simultaneously with one hand while maintaining grip on the control bar, eliminating the need to release the bar to access the quick release.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated control mechanism serves as an intermediary between the kiter's hand and the kite system, providing both quick release and depower capabilities through a single interface on the control bar. This intermediary position allows continuous control while enabling emergency release functions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a kiter maintains grip on the control bar with both hands for steering, then steering control is maintained, but the kiter cannot quickly activate the quick release at the waist without releasing the bar

Engineering Contradiction:

Improvesteering controlVSAvoidemergency release capability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent merges the emergency release function with the steering control by placing the quick release mechanism directly on the control bar. This allows the kiter to maintain two-handed grip for steering while having immediate access to the release function through the integrated control mechanism.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The quick release mechanism is pre-positioned on the control bar in a readily accessible location, allowing the kiter to activate it immediately without needing to move their hands from the steering position. The function is prepared in advance at the optimal location for emergency activation.

Inventive Principle:

Principle #10Preliminary action

3Force

If a traction kite generates enough force to pull a person or vehicle, then the kite provides sufficient pulling power for kiteboarding, but the pulling force increases exponentially with slightest movement, creating dangerous situations

Engineering Contradiction:

Improvepulling powerVSAvoiddeath-loop danger

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The patent implements a dynamic depower mechanism that allows real-time adjustment of the kite's pulling power. The depower handle enables the kiter to dynamically change the brake line tension, adjusting the kite's power output from full force to reduced power states, allowing control adaptation to varying wind conditions and kite movements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The integrated control mechanism provides continuous feedback control by allowing the kiter to monitor kite power and adjust the depower handle accordingly. The system responds to the kiter's input in real-time, enabling continuous adjustment of pulling force to prevent exponential force increases that lead to death-loops.

Inventive Principle:

Principle #23Feedback

4Reliability

If a kiter needs to release from the kite pull immediately, then safety is improved, but legacy quick releases require the kiter to divert attention from the kite to the waist-mounted release

Engineering Contradiction:

Improvesafety releaseVSAvoidvisual attention on kite

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent combines the safety release function with the primary control interface by mounting the quick release on the control bar itself. This merging eliminates the need for separate waist-mounted releases, allowing the kiter to maintain visual attention on the kite while having immediate access to the release function through the integrated control mechanism in their hand.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A kite rigging control apparatus and method of use. A hand-actuated bailout trigger and optional depower handle is incorporated into the rigging of the traction kite. Should the kite begin to overpower the kiter, the kiter may immediately and easily depower the kite or readily activate the bailout trigger which immediately ceases the pull of the kite. The kiter may then safely recover the kite.
