Kite Safety Device Pivot Lever Spring-Loaded Reassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety devices for kites require complex assembly after triggering, often necessitating two hands and manual adjustment of the grip sleeve, making it difficult to reassemble under unfavorable conditions such as strong waves.
Innovation Solution
A safety device with a pivoting lever that is slidably mounted and elastically prestressed, allowing the loop end section to be moved from a release position to a closed position without adjusting the gripping sleeve, simplifying the assembly process and enabling single-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the grip sleeve is moved into the open position to reassemble the safety device, then the pin or pivot lever can be moved into an open position for insertion, but this requires two hands and manual adjustment which is difficult under unfavorable conditions
Solution Approach 1:
The pivot lever is designed with dynamic characteristics, being spring-loaded to automatically return to the closed position after release. This dynamic design eliminates the need for manual repositioning of the grip sleeve during assembly, as the lever self-adjusts to facilitate loop end section insertion without requiring two-handed operation
Solution Approach 2:
The spring-loaded pivot lever performs self-service by automatically returning to its closed position after the release mechanism is activated. This self-returning mechanism eliminates the need for user intervention to reposition components, enabling single-handed assembly and improving ease of operation under challenging conditions
2Ease of operation
If the pivot lever is fixed in position, then the structure is simpler, but the loop end section cannot be easily moved from release position to closed position without adjusting the grip sleeve
Solution Approach 1:
The pivot lever transitions from a fixed position to a dynamic, spring-loaded position that automatically returns to closed. This dynamic mounting enables the loop end section to be easily moved from release to closed position without grip sleeve adjustment, as the spring mechanism provides automatic positioning assistance
Solution Approach 2:
The pivot lever's positional parameter is changed from fixed to variable through spring loading. This parameter change allows the lever to move between open and closed positions automatically, facilitating easier reassembly without requiring manual adjustment of the grip sleeve while maintaining structural integrity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for effortless reassembly of the safety device without the need to manually adjust the grip sleeve, enhancing usability in challenging conditions and preventing accidental opening due to kite tension.
Implementation Method 1
the pivot lever is elastically preloaded in the direction of a functional position, for example in the direction of the basic position of the grip sleeve, and can be displaced into an opening position by applying the loop end section against this preload
