Water Ski Boot Lateral Blade Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-ski gliding sport devices and boot assemblies face challenges in controlling board trajectory and maintaining lateral rigidity, particularly during turns, leading to deformation under significant stresses and reduced response time.
Innovation Solution
Incorporation of first and second rigid lateral blades on either side of the boot assembly, connected to the board and boot structure, providing deflection and increased lateral rigidity, with adjustable connections to enhance responsiveness and simplify production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid lateral blades are added to the boot assembly, then lateral rigidity and board responsiveness are improved, but device complexity increases
Solution Approach 1:
The boot assembly is segmented by adding separate rigid lateral blades as distinct structural elements. These blades are connected to both the board and the boot structure, creating modular reinforcement that improves lateral rigidity without requiring complete redesign of the boot assembly.
Solution Approach 2:
The device combines different structural elements (board, boot assembly, and rigid lateral blades) into a composite system. The rigid lateral blades act as reinforcing elements that work together with the existing boot and board structures to enhance overall lateral rigidity and responsiveness.
2Manufacturing precision
If rigid lateral blades are added to improve trajectory control, then manufacturing complexity increases, but adaptability remains
Solution Approach 1:
The lateral blades are designed as separate, attachable components rather than integrated parts of the boot assembly. This segmentation allows for independent manufacturing and assembly, simplifying production while maintaining precise trajectory control through the rigid blade structure.
Solution Approach 2:
The connection between the rigid lateral blades and the boot assembly allows for potential adjustment and adaptation. The blades can be positioned and secured to provide precise trajectory control while maintaining ease of manufacture through modular assembly processes.
3Speed
If the rigid structure is made more rigid to reduce deformation under stress, then response time improves, but lateral deformation resistance may be compromised
Solution Approach 1:
Instead of increasing the rigidity of the existing boot structure in all directions, rigid lateral blades are added specifically in the lateral dimension. This targeted approach improves response time by reinforcing the structure where needed while maintaining flexibility and resistance to deformation in other areas.
Solution Approach 2:
The rigid lateral blades provide localized reinforcement at critical points where lateral forces are applied during turning. This local quality approach enhances response time and lateral deformation resistance precisely where needed, rather than uniformly increasing rigidity throughout the entire boot assembly.

Function Achieved in This Case
The solution enhances the board's responsiveness and precision during turns by providing lateral reinforcement, allowing for better control of the board's trajectory and quicker exit from the water, while maintaining safety and adaptability to user preferences.
Implementation Method 1
The rigid lateral blade has a deflection function when it is immersed in water, for example in a turn
