Single Lever Ski Binding Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ski-binding locking mechanisms require multiple levers and tools for precise positioning, are time-consuming, and may inadvertently change position under force, especially for advanced skiers who need frequent adjustments based on varying snow conditions.
Innovation Solution
A single lever locking mechanism with a lug that engages with a notch on the mounting plate, allowing for quick and precise adjustment of the ski-binding's position without additional tools, using a pivoting arrangement that biases the lever to remain locked in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple levers and tools are used for locking the ski-binding, then the positioning is precise and secure, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The patent combines multiple locking functions into a single lever mechanism. The one-piece lever integrates the locking, positioning, and securing functions that previously required multiple separate levers and tools, allowing the skier to adjust the binding position quickly with a single action while maintaining precise positioning through the lever's engagement with notches in the mounting plate
Solution Approach 2:
The single lever is designed to perform multiple functions: it acts as a locking mechanism, a positioning device, and a securing element simultaneously. The lever engages with notches at different positions along the mounting plate to provide precise positioning while its spring-loaded design maintains secure engagement, eliminating the need for separate tools for each function
2Ease of operation
If a single lever is used for locking the ski-binding, then the adjustment process is quick and simple, but the locking mechanism may inadvertently change position under force
Solution Approach 1:
The spring-loaded lever automatically engages with the notches in the mounting plate and maintains constant pressure to secure the binding position. The spring mechanism self-adjusts to maintain engagement force, and the lever's design includes features that prevent accidental disengagement while allowing intentional release by the skier, providing both ease of operation and reliability
Solution Approach 2:
The spring-loaded design anticipates forces that might cause the lever to disengage by maintaining constant engagement pressure. The spring acts as a cushioning element that absorbs shocks and forces during skiing, ensuring the lever remains securely engaged with the notches unless intentionally released by the skier
3Reliability
If conventional locking mechanisms are used, then the binding is securely locked, but the skier loses time stopping to adjust the position mid-run
Solution Approach 1:
The patent merges the locking and positioning functions into a single lever operation, allowing the skier to quickly adjust the binding position mid-run without the time-consuming process of manipulating multiple levers and tools. The single lever can be rapidly engaged or disengaged from notches, maintaining locking security while improving skiing efficiency by minimizing stop time
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 rapid and accurate positioning of the ski-binding, reducing the time spent adjusting and minimizing the risk of accidental repositioning during use, while maintaining secure engagement without the need for multiple levers or tools.
Implementation Method 1
the lever is provided with an indent portion sized and shaped to receive at least a fingertip of an operator of the lever, thereby enabling the operator to grasp the lever when in the engaged position and actuate the lever to the disengaged position

AI summary
A locking mechanism for a ski-binding, the locking mechanism comprising only one lever adapted to be pivoted between an engaged and a disengaged position, wherein the lever comprises at least one lug, the at least one lug adapted to engage with a notch formed in a mounting plate in the engaged position, wherein the lug is adapted to hold the ski-binding in a non-sliding manner when engaged with the notch, and wherein the locking mechanism does not comprise a second or more lever, wherein the lever is adapted to be pivotingly engaged with the ski-binding at a proximal end of the lever, and wherein the lug is positioned between the distal end and the proximal end of the lever and wherein the proximal end of the lever is integrally formed with the ski-binding, wherein the proximal end of the lever is adapted to have an increased flexibility compared to the lever and ski-binding, thereby allowing pivoting movement of the lever at the proximal end.
