Splitboard Joining Device Torsional Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing splitboard joining devices fail to fully constrain the movement of skis relative to each other in all directions, particularly lacking in torsional stiffness and effective compression, leading to reduced performance and control during snowboarding.
Innovation Solution
A splitboard joining device with a first and second attachment that create tension and compression between the skis, featuring a lever-driven tension element and adjustable set screw for precise fit, preventing upward movement and rotation, and allowing easy separation, thereby enhancing torsional stiffness and tip-to-tail flex.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing splitboard joining devices are used to join skis, then the skis can be connected, but the device fails to fully constrain movement in all directions, resulting in insufficient torsional stiffness and compression
Solution Approach 1:
The joining device is divided into separate attachments that connect to each ski independently, with tension elements that can be individually adjusted. This segmentation allows each component to be optimized for specific functions (compression, tension, rotation prevention) while maintaining overall structural integrity and torsional stiffness.
Solution Approach 2:
The patent introduces multi-directional constraint mechanisms that operate in different spatial dimensions. Attachments include features that constrain movement in vertical, horizontal, and rotational dimensions simultaneously, providing comprehensive control over ski relative positioning to achieve full constraint in all directions.
2Stability of the object's composition
If a rigid joining structure is used to prevent ski movement, then torsional stiffness improves, but the device becomes difficult to operate and separate
Solution Approach 1:
The joining device incorporates dynamic elements such as adjustable tension elements and movable attachments that can transition between locked and unlocked states. This allows the structure to be rigid and stable during snowboarding operations, while enabling easy separation when needed by simply releasing the dynamic locking mechanisms.
Solution Approach 2:
The patent uses intermediary components such as tension elements and attachment interfaces that act as mediators between the skis. These intermediaries provide the necessary constraint forces to maintain stable ski positioning, while their design allows for controlled release and easy separation when the joining function is no longer required.
3Strength
If attachments are tightly clamped to prevent shearing and sliding, then ski connection strength improves, but adjustment precision and fit control become more difficult
Solution Approach 1:
The patent incorporates adjustable parameters in the attachment design, such as movable set screws and adjustable tension elements, that allow users to precisely control the tightness and fit of the connection. This enables optimization of both connection strength and fit precision by adjusting parameters like clamping force and attachment positioning to match specific ski configurations and performance requirements.

AI summary
The present disclosure relates to splitboard joining devices. The splitboard joining devices can quickly and easily join the skis of a splitboard to create a snowboard. The devices can clamp the splitboard skis in a direction perpendicular and parallel to the seam of the splitboard and normal to the top surface of the splitboard skis. This can prevent the splitboard skis from moving up and down relative to each other, moving apart in a direction perpendicular to the seam, sliding relative to each other in a direction parallel to the seam, and rotating about the seam. The splitboard joining devices can constrain rotation and movement about the seam of the splitboard to make a splitboard ride like a normal snowboard and enhance a rider's experience on a splitboard.
