Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for adjusting the longitudinal position of ski boot binding elements on a gliding board are complex, require tools, are not user-friendly, and are costly due to the use of multiple components and metallic materials, making them unsuitable for quick adjustments and potentially unsafe.
Innovation Solution
A binding element with a lever and cam mechanism that allows for easy adjustment between high and low positions, using a simple lever and notching part design, which can be manufactured from plastic materials, eliminating the need for complex components and tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a crankshaft and toothed bar mechanism is used for adjustment, then the binding element can be locked in position, but the device becomes complex and requires metallic materials that are expensive to manufacture
Solution Approach 1:
The patent extracts the essential function of position locking from the complex crankshaft-toothed bar mechanism and implements it through a simplified lever system with cam action. The lever with cam profile directly engages the toothed bar to provide locking without requiring the complex crankshaft mechanism, thereby maintaining reliability while reducing device complexity.
Solution Approach 2:
The patent changes the mechanical parameters by replacing metallic materials with plastic materials for the lever and related components. This parameter change maintains the functional requirements for locking and positioning while significantly reducing manufacturing complexity and cost, eliminating the need for expensive metal fabrication.
2Reliability
If a lock mechanism requiring a tool is used for adjustment, then the position can be secured, but the adjustment process becomes inconvenient and time-consuming
Solution Approach 1:
The patent implements self-service adjustment by designing a lever mechanism that can be operated directly by the user without requiring external tools. The lever with cam action allows the user to manually release and reposition the binding element by simply manipulating the lever, making the system self-sufficient and eliminating the need for screwdrivers or other tools.
Solution Approach 2:
The patent introduces dynamic operation through the lever mechanism that can be quickly moved between locked and released positions. The cam profile enables rapid transition between states, allowing the binding element to be dynamically adjusted from a fixed locked position to a movable released position and back, greatly improving ease of operation compared to static tool-required locks.
3Reliability
If multiple components are used for adjustment mechanism, then the locking function is achieved, but the overall volume of the accessory increases
Solution Approach 1:
The patent merges multiple components into a more compact integrated structure. The lever with cam profile is designed to work directly with the toothed bar and notching part in a compact arrangement, eliminating the need for separate crankshaft, strip, and mounting components. This merging of functions into a more integrated system reduces the overall volume of the binding element accessory.
4Ease of manufacture
If a complex mounting method is used for the adjustment mechanism, then the components can be assembled, but the process becomes difficult and not user-friendly
Solution Approach 1:
The patent segments the binding element into modular components including the lever assembly, toothed bar, and notching part that can be independently manufactured and then easily assembled. This segmentation allows each component to be optimized for manufacturing while simplifying the overall assembly process, making the mounting procedure more user-friendly compared to integrated complex mechanisms.

AI summary
The element has a lever (20) co-operating with a notching part by a cam, so that an actuation of the lever allows positioning of the notching part along two bottom and top positions corresponding respectively to a configuration of adjusting and blocking the fixation element on a board. The notching part includes an opening extended transversely, and is crossed by an axle of the lever, where the axle of the lever includes a cam forming part cooperating with an interior surface of the opening of the notching part. Independent claims are also included for the following: (1) a device for fixing a shoe on a sliding board, comprising a stop (2) a method for assembly a fixation element.
