Solution Overview

Problem

Conventional ski bindings are complex and difficult to assemble, with guide profiles and toothed belts forming a large, rigid metal part combined with a plastic base plate, making integration into the ski challenging and the assembly process cumbersome.

Innovation Solution

The guide profiles are integrally formed or attached to a one-piece plastic base part, with a toothed belt inserted into a recess, ensuring positive locking of the shoe holder unit, allowing easy arrangement and integration, and a threaded part for rotary adjustment to secure the shoe holder unit in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If guide profiles and toothed belt form a large, rigid metal part combined with a plastic base plate, then the structural strength and reliability are improved, but the device complexity and assembly difficulty increase

Engineering Contradiction:
Improvestructural strengthVSAvoidassembly difficulty
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The base part is divided into a plastic base plate and a separate metal reinforcement element with guide profiles and toothed belt. This segmentation allows each component to be manufactured independently with optimal materials and processes, then assembled together, reducing overall complexity while maintaining structural strength.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The metal reinforcement element with guide profiles and toothed belt is combined with the plastic base plate to form an integrated base part assembly. This merging provides the structural strength of metal with the manufacturing advantages of plastic, achieving both reliability and ease of assembly.

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If guide profiles and toothed belt form a large, rigid metal part combined with a plastic base plate, then the structural stability is improved, but the ease of manufacture and integration into ski deteriorate

Engineering Contradiction:
Improvestructural stabilityVSAvoidintegration into ski
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

By separating the guide profiles and toothed belt into a distinct metal reinforcement element, the design enables independent manufacturing of the base plate and reinforcement. This segmentation simplifies the integration process into the ski, as the plastic base plate can be directly molded or attached to the ski while the metal element is separately positioned and secured.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The combination of plastic base plate and metal reinforcement element creates a composite structure that leverages the advantages of both materials. The plastic provides ease of manufacture and integration, while the metal provides structural stability, achieving both goals simultaneously.

Inventive Principle:
Principle #40Composite materials

3Manufacturing precision

If the shoe holder unit is held on the base part with a threaded part engaging the toothed belt, then the positioning precision and reliability are improved, but the device complexity increases

Engineering Contradiction:
Improvepositioning precisionVSAvoidnumber of components
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The threaded part is integrated into the shoe holder unit housing rather than being a separate component. This merging reduces the number of parts while maintaining the precise positioning function through the engagement of the threaded part with the toothed belt on the reinforcement element.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The toothed belt on the metal reinforcement element serves as an intermediary mechanism between the threaded part and the base part. This intermediary provides precise positioning through the threaded engagement while simplifying the overall structure by eliminating the need for complex mounting mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

This design simplifies the construction and assembly of ski bindings, ensuring correct placement of the shoe holder unit and facilitating adaptation to different ski boot sizes, while maintaining flexibility and avoiding stiffening during ski flex movements.

Implementation Method 1

The housing of the shoe holder unit on the heel side is regularly resiliently supported on the abutment part, specifically via a so-called push-on spring system. This makes it possible for the shoe holder unit on the heel side to give way to the rear end of the ski during flex movements of the ski

Implementation Method 2

a threaded part, which is designed in the manner of a worm screw and is rotatably mounted in an abutment part of the housing and engages with a sector of its threaded outer circumference in a toothed band on the base part

AI summary

The binding (1) for a snowboard has an integral base (2) on which it is mounted for longitudinal sliding. The base has a toothed strip (6) which engages with a threaded section of a resistant bearing (23) to allow adjustment of the resistance bearing in the longitudinal direction. There is a guide profile (3) integral with the base and the toothed strip fits in a cut out in the base.
