Kite Control Bar with Motorized Trimming and Emergency Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kite control bars lack ease of use and operational safety, particularly in trimming and emergency situations, and do not provide comprehensive real-time feedback to users.
Innovation Solution
A kite control bar equipped with an electric motor-driven winch, a charging port for battery power management, an emergency actuation mechanism, and a radio module for remote control, along with an electrical display for real-time parameter feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual trimming is used with a winch and twist handle, then the kite can be trimmed, but the operation requires manual effort and time
Solution Approach 1:
The patent replaces the manual mechanical winch operation with an electric motor system. The motor is controlled by a simple switch or sensor, automatically winding or unwinding the control lines to trim the kite. This substitution eliminates the need for manual cranking and reduces the time required for trimming operations.
Solution Approach 2:
The system incorporates automatic trimming capability where the motor responds to user input (via switch or sensor) to perform the trimming action autonomously. The motor automatically adjusts the control line length without requiring manual intervention for each adjustment, making the system serve itself in the trimming function.
2Reliability
If no emergency actuation is provided, then the device is simpler, but operational safety is reduced
Solution Approach 1:
The emergency actuation mechanism is pre-configured and always ready to activate. In case of motor failure or other emergencies, the system can immediately release the control lines without requiring complex diagnostic procedures. This preliminary preparation ensures safety while keeping the activation mechanism simple.
Solution Approach 2:
The emergency actuation is designed as a separate, independent mechanism from the motor system. It can be a simple mechanical release or a separate button that directly disengages the control lines, extracted from the complex motor control system. This separation maintains safety functionality while minimizing added complexity.
3Loss of information
If real-time data display is added, then user feedback is improved, but device complexity increases
Solution Approach 1:
The display unit is designed to show multiple parameters (line length, trim position, motor status) using a single integrated interface. This multi-functional display provides comprehensive real-time feedback without requiring separate indicators for each parameter, thus limiting the increase in device complexity while maximizing information delivery.
4Ease of operation
If electric motor is used for trimming, then ease of operation is improved, but dependency on power supply increases
Solution Approach 1:
The emergency actuation mechanism is pre-configured and always ready to activate. In case of motor failure or other emergencies, the system can immediately release the control lines without requiring complex diagnostic procedures. This preliminary preparation ensures safety while keeping the activation mechanism simple.
Solution Approach 2:
The emergency actuation is designed as a separate, independent mechanism from the motor system. It can be a simple mechanical release or a separate button that directly disengages the control lines, extracted from the complex motor control system. This separation maintains safety functionality while minimizing added complexity.
