Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gliding board bindings face a challenge in achieving reliable release behavior with higher release forces while maintaining easy operation, as high elastic forces required for sporty driving styles increase the risk of false triggering and reduce operating comfort.
Innovation Solution
A front unit with a movable actuation element and release element that can be selectively coupled or decoupled using a coupling device, allowing for independent operation of the binding actuation and release functions, enabling a high release force for sporty driving while ensuring comfortable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high elastic force is used in the engagement means, then reliable engagement and prevention of false triggering during sporty driving is improved, but the operating force required to release the binding increases, reducing operating comfort
Solution Approach 1:
The binding system is divided into two independent functional parts: the engagement means with high elastic force for reliable shoe retention, and the actuating device with low operating force for comfortable release. The decoupling mechanism allows these two functions to operate independently, enabling high engagement force without requiring high release force.
Solution Approach 2:
A decoupling mechanism acts as an intermediary between the actuating device and the engagement means. This intermediary allows the actuating device to operate with low force while still controlling the high-force engagement means through the coupling mechanism, resolving the force mismatch between operation comfort and engagement reliability.
2Reliability
If high release force is used to prevent false triggering during vigorous driving maneuvers, then safety and reliable triggering behavior is improved, but the force required to manually operate the binding increases, reducing ease of operation
Solution Approach 1:
The coupling between the actuating device and engagement means is made dynamic and adjustable rather than fixed. The decoupling mechanism allows the system to switch between coupled and decoupled states, enabling the actuating device to operate with low force while maintaining the ability to transmit high forces when needed for reliable triggering.
Solution Approach 2:
The functional separation divides the binding into independent segments: the actuating device for low-force operation and the engagement means for high-force retention. This segmentation allows each component to be optimized for its specific function without compromise.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design guarantees reliable triggering behavior during sporty maneuvers while allowing for easy and low-force operation, enhancing both safety and convenience.
Implementation Method 1
an elastic means is therefore generally used in order to exert a predetermined compressive force from the engagement means on the shoe
Implementation Method 2
the actuating element is set up for movement in the binding actuation direction by a spring-biased actuating element
