Snowboard Controller Joints for Flexibility and Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snowboard bindings reduce the flexibility of snowboards due to their rigid nature, contradicting the flexible properties of the board, which affects controllability and user connection.
Innovation Solution
A snowboard controller with a base and joints that allow a predetermined movable range, incorporating direct and indirect joints with stretchable members and adjustable resistance units to maintain flexibility while enhancing controllability, including a torsion control unit for stable turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bindings are firmly fixed to the snowboard with rigid fixtures, then the bindings can receive and transfer operational forces effectively, but the flexibility of the snowboard is reduced
Solution Approach 1:
A controller is introduced as an intermediary component between the bindings and the snowboard. The controller includes a base with multiple joints that connect to the snowboard, allowing the rigid bindings to be coupled to the flexible board through a mechanism that preserves board flexibility while maintaining force transfer capability.
Solution Approach 2:
The controller is divided into multiple independent joints (front joint, middle joints, rear joint) that can move independently within their respective movable ranges. This segmentation allows each joint to accommodate local deformations while maintaining overall connection, thus preserving the snowboard's flexibility.
2Stability of the object's composition
If multiple independent joints are used to connect the base to the snowboard, then the flexibility is maintained, but the connectedness between the user and the board is degraded
Solution Approach 1:
Multiple joints are merged into a single integrated controller structure with a common base. The joints work cooperatively as a unified system to control board bending, maintaining both flexibility and connectedness. The base integrates the functionality of all joints into one controllable unit.
Solution Approach 2:
The joints are designed with predetermined movable ranges that allow dynamic adaptation to different riding conditions. The controller transitions from a static rigid structure to a dynamic system that can adjust its rigidity and flexibility based on operational needs, improving both flexibility preservation and user control.
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 increases controllability and stability of the snowboard without reducing its flexibility, allowing it to closely follow rugged surfaces and absorb shocks, while adjusting resistance for varying conditions and user skills.
Implementation Method 1
The indirect joints include stretchable joining members that are stretchable in a longitudinal direction of the indirect joints
Implementation Method 2
a stretch-resistance providing unit that provides stretch resistance in the stretchable joining member to control bending of the board

AI summary
A snowboard controller includes a base placeable on an upper surface of a board for a snowboard, a plurality of joints that join the base to the upper surface of the board. The plurality of joints include one joint being a direct joint at which the base is directly joinable to the board in a rotatable manner, and other joints being indirect joints at which the base is indirectly joinable to the board with joining members. The indirect joints control bending of the board using the direct joint as a base point.
