Removable Ski Binding Toe Piece for Weight-Safety Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ski bindings face challenges in balancing weight for ascent with the need for safety during descent in deep snow, particularly due to the weight of integrated components that complicate the ascent process.
Innovation Solution
A ski binding system featuring a toe piece attachment with a second holding device that can be manually removed from the base for ascent, allowing for a lightweight configuration during climbing and secure engagement for downhill skiing, utilizing pivot joints, spring elements, and a connecting device for easy detachment and reattachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second holding device is integrated into the base for downhill skiing safety, then safety during descent is improved, but weight during ascent increases
Solution Approach 1:
The binding system is divided into two functional modules: a first holding device for ascent mode and a second holding device for descent mode. The second holding device can be detached from the base, allowing the skier to separate the heavy downhill skiing components from the lightweight uphill climbing configuration, thus resolving the weight-safety contradiction.
Solution Approach 2:
The second holding device is designed to be dynamically configurable - it can be attached to the base when downhill skiing safety is needed and detached when weight reduction for ascent is prioritized. This dynamic reconfiguration allows the system to adapt its weight and safety characteristics based on the current skiing phase.
2Reliability
If the second holding device is integrated for secure downhill connection, then reliability during descent is improved, but device complexity increases
Solution Approach 1:
The connection system is segmented into a connecting device with engagement structure on the second holding device and a counter-engagement structure on the base. This modular segmentation allows each component to be optimized independently - the engagement structures provide secure downhill connection while the separate modular design actually reduces overall system complexity compared to a fully integrated system.
3Weight of moving object
If the second holding device is made removable for lightweight ascent, then weight during ascent is reduced, but ease of operation decreases
Solution Approach 1:
The connecting device incorporates dynamic engagement and disengagement mechanisms that allow the second holding device to be quickly attached to and detached from the base. The engagement structure with counter-engagement structure enables tool-free operation, making the removable design as easy to operate as an integrated system while still providing weight reduction benefits.
4Ease of operation
If the second holding device is made manually removable, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The connecting device is designed to be operated manually by the user without requiring external tools or complex mechanisms. The engagement structure and counter-engagement structure are configured to allow intuitive attachment and detachment through simple manual actions, making the system self-servicing and avoiding the need for additional complex control mechanisms.
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
Enables safe and efficient skiing by reducing weight during ascent while maintaining safety and security during descent, allowing for seamless transitions between ascent and descent modes without the need for tools.
Implementation Method 1
at least one spring element which biases the first ski boot holder and the second ski boot holder towards one another
Implementation Method 2
The first ski boot holder is connected to the holding device body in a first pivot joint, a second ski boot holder which at least laterally surrounds the front end of the sole, wherein the second ski boot holder is connected to the holding device body in a second pivot joint
Implementation Method 3
the engagement structure and the counter-engagement structure form a pivot axis about which the second holding device is pivotable relative to the base or the jaw body
