Adjustable Hand Tether for Surfboards Using Segmented Lifting Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric surfboards lack a hand tether system that can accommodate surfers of varying heights, making it difficult for users of different sizes to maintain balance while surfing.
Innovation Solution
A surfing device with an adjustable hand tether system, comprising a pliable tether with equally-spaced scales and lifting rings, allowing users to quickly adjust the length to match their height, and an ergonomically designed handle for comfortable grip, with optional light-reflective material for enhanced safety at night.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length hand tether is used, then the structure is simple, but it cannot accommodate surfers of varying heights
Solution Approach 1:
The hand tether is divided into multiple segments with lifting rings at different heights. Users can select different lifting rings based on their height, effectively segmenting the single tether into multiple usable lengths. This allows one tether to serve multiple height requirements without requiring multiple separate tethers.
Solution Approach 2:
The tether system transitions from a fixed static structure to a dynamic adjustable structure. The pliable nature of the tether combined with selectable lifting rings enables the effective length to change based on user needs, making the system adaptable rather than rigid.
2Ease of operation
If a non-pliable tether is used, then the length is stable, but it is difficult to adjust for different users
Solution Approach 1:
Lifting rings are pre-positioned at specific intervals along the tether at manufacturing stage. Users don't need to create adjustment points during use; the adjustment options are already prepared in advance, making the adjustment process simple and quick.
Solution Approach 2:
The lifting rings serve as intermediary elements between the tether and the user's hand. They provide predetermined attachment points that facilitate easy adjustment while maintaining tether integrity. The rings act as mediators that enable length selection without requiring complex mechanisms.
3Object-affected harmful factors
If no light-reflective material is added, then the tether is simpler, but visibility at night is reduced
Solution Approach 1:
The tether incorporates light-reflective material that changes its optical properties under different lighting conditions. During the day, the material appears normal, but at night it reflects light to enhance visibility. This passive optical change improves safety without requiring active components or power sources.
