Touring Binding Brake Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake arrangements for touring bindings are complex, heavy, and have stability issues due to their design, which complicates the locking mechanism and increases weight.
Innovation Solution
A brake arrangement with a locking element that is adjustable between active and passive positions, allowing for conversion of pivoting movements into linear movements along the ski's longitudinal direction, eliminating the need for heel unit displacement, and utilizing resilient elements to preload the locking mechanism for simple latching in the sliding position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heel unit is made longitudinally displaceable to lock the brake arrangement, then the brake arrangement can be locked in sliding position, but the structure becomes complicated and weight increases
Solution Approach 1:
The brake arrangement is separated into independent functional components: a stationary heel unit, a displaceable brake pedal, and a hook mechanism. This segmentation allows the brake locking function to be achieved without requiring the entire heel unit to be displaceable, thus reducing structural complexity while maintaining reliability.
Solution Approach 2:
The longitudinal displacability function is extracted from the heel unit and assigned specifically to the brake pedal and hook mechanism. This extraction allows the heel unit to remain simple and stationary while the braking and locking functions are handled by dedicated components, resolving the contradiction between reliability and complexity.
2Reliability
If the heel unit is made longitudinally displaceable to lock the brake arrangement, then the brake arrangement can be locked in sliding position, but weight increases
Solution Approach 1:
By segmenting the brake system into a stationary heel unit and a displaceable brake pedal with hook, the overall moving mass is reduced. Only the necessary braking components need to be displaceable, not the entire heel unit, thus reducing weight while maintaining the locking function.
Solution Approach 2:
The displacability requirement is extracted and applied only to the brake pedal and hook mechanism rather than the entire heel unit. This selective application minimizes the weight of moving parts while preserving the essential brake locking functionality.
3Reliability
If the heel unit is made longitudinally displaceable to lock the brake arrangement, then the brake arrangement can be locked in sliding position, but stability is adversely affected
Solution Approach 1:
The system is segmented into a stable, stationary heel unit and a displaceable brake pedal assembly. This segmentation allows the heel unit to maintain its stability and structural integrity while the brake pedal provides the necessary displacability for locking functionality.
Solution Approach 2:
The longitudinal displacability is extracted from the heel unit and assigned to the brake pedal and hook mechanism. This extraction preserves the heel unit's stability and structural composition while enabling the brake arrangement to be locked in the sliding position through the displacable components.
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 provides a lightweight, stable, and simplified brake arrangement that effectively locks in the sliding position without displacing the touring binding, ensuring safety and ease of operation while preventing ski loss during falls or uphill skiing.
Implementation Method 1
at least one first resilient element (50) which is designed to preload the brake arrangement (10) into the braking position
Implementation Method 2
the locking element (60) and the actuating element (80) being configured such that a pivoting movement of the actuating element (80) about a pivot axis (82) causes a linear movement of the locking element (60) in the longitudinal direction of the ski

AI summary
A brake arrangement for a touring binding adjustable between a braking position and a sliding position, including: a base having a fastening arrangement; a pedal; at least one brake arm mounted on the base and on the pedal; at least one first resilient element to preload the brake arrangement into the braking position; a locking element that is linearly displaceable along a longitudinal direction of the ski to adjust between an active position, which locks the brake arrangement in the sliding position, and a passive position; and an actuating element mounted on the brake arrangement pivotable about a pivot access, the actuating element adjustable between a locking position, where the locking element is set into the locking position, and a release position, where the locking element is set into the passive position, and wherein a pivoting movement of the actuating element causes a linear movement of the locking element.
