Splitboard Binding Fixation Using Sliding Bearing Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing splitboard binding systems are structurally complex, prone to functionality issues when frozen or snow-covered, and require multiple movable parts that increase production costs and risk of damage, making them difficult to manipulate and maintain.
Innovation Solution
A simplified design using sliding bearing pins with coaxial eyes and stoppers on the board and clamp, where the pins have circular recesses and a truncated conical tip, allowing for easy fixation and release without movable parts, even in snowy conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex fixation systems with multiple movable parts are used, then the fixation functionality can be achieved, but the system becomes prone to functionality issues when frozen or snow-covered and increases production costs
Solution Approach 1:
The patent removes all movable functional parts (swiveling levers, turn over stoppers, arms) from the fixation system, extracting only the essential coupling function. The base portion and clamp are coupled directly through pins inserted into eyes, eliminating intermediate movable components that cause complexity and reliability issues in snowy conditions.
Solution Approach 2:
Instead of using movable parts that move during operation, the patent inverts the approach by using fixed structural elements (pins and eyes) that remain stationary. The fixation is achieved through the geometric arrangement and insertion of pins into coaxial eyes, rather than through movement of levers or arms.
2Reliability
If multiple movable parts are used for fixation, then the fixation mechanism can be implemented, but the risk of damage during repeated resetting increases
Solution Approach 1:
The patent extracts all movable parts from the fixation system, leaving only fixed pins and eyes. This eliminates the wear and damage risks associated with repeated movement and resetting of levers, arms, and stoppers, as these components are completely removed from the design.
3Reliability
If structural nodes are completed with swiveling or turn over levers, stoppers or arms, then axial fixation of pins in eyes is achieved, but production costs increase
Solution Approach 1:
The patent removes swiveling levers, turn over stoppers, and arms from the fixation nodes, achieving axial fixation of pins in eyes through the direct insertion and geometric arrangement of the pins themselves. This simplification dramatically reduces production costs by eliminating complex movable components.
4Reliability
If independent pins are used for coupling base portion and clamp, then the coupling can be achieved, but manipulation during mutual coupling becomes very complicated
Solution Approach 1:
The patent merges the pin and eye structures into a unified coupling system where pins are inserted directly into coaxial eyes on the base portion and clamp. The stoppers on the eyes and circular recesses on the pins work together as an integrated mechanism, simplifying manipulation to a single insertion and rotation motion rather than complex multi-step coupling procedures.

AI summary
Systems and methods for fixing a binding board to skis that are removably connected together to form of a splitboard are described herein. In some cases, the described systems use a sliding and removable setting of bearing pins in eyes that are formed on adjacent areas of the board and a clamp that is fixed to the skis. The essence of the invention is a fixation of lateral parts of the eyes by stoppers which partially overreach into cross sections of the eyes. A diameter of the bearing pins basically corresponds with a diameter of the eyes. The bearing pins are equipped with circular recesses for engaging with the stoppers and also with end parts that each have a truncated conical tip.
