Solution Overview

Problem

Existing sliding plates for ski jumping facilities lack sufficient suspension functionality between the plate-shaped element and sliding knobs, restricting additional functionalities and not allowing significant relative movement, which affects the sliding behavior and force absorption.

Innovation Solution

The sliding plate features spring means arranged between sliding knob spring sections and plate spring sections, with detachable fastening means for easy replacement, and uses polymer elements like adhesives or O-rings for elasticity, allowing for relative movement and integrating further functionalities like force measurement and water management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If spring means are arranged between sliding knobs and plate-shaped element, then suspension functionality is improved, but device complexity increases

Engineering Contradiction:
Improvesuspension functionalityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the spring means directly into the sliding knob structure, merging the suspension function with the existing sliding knob component. This integration approach provides sufficient suspension functionality while avoiding the need for separate, additional suspension components, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sliding knob is designed to serve multiple functions: it provides the sliding function, contains the spring means for suspension, and includes detachable fastening means for secure attachment. This multi-functionality reduces the need for separate components, balancing improved suspension with controlled complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of repair

If detachable fastening means are used, then ease of repair is improved, but structural integrity may worsen

Engineering Contradiction:
Improveease of replacementVSAvoidstructural integrity
Core Design Contradiction:
Ease of repairVSStrength

Solution Approach 1:

The fastening system is designed to be dynamically adjustable - firmly securing the sliding knob during operation to maintain structural integrity, while allowing easy detachment for replacement. The detachable fastening means enables transition between a secure locked state and an easy-to-remove state, balancing strength and repairability.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If sliding knobs allow significant relative movement, then sliding behavior is improved, but suspension functionality may worsen

Engineering Contradiction:
Improvesliding behaviorVSAvoidsuspension functionality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The spring means are designed with specific elastic properties that allow controlled relative movement between the sliding knob and plate-shaped element. The elastic force provides suspension while permitting the necessary sliding motion, optimizing both sliding behavior and suspension functionality through parameter optimization of the elastic component.

Inventive Principle:
Principle #35Parameter changes

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 provides enhanced suspension functionality, improved sliding behavior, and the ability to integrate additional features like force measurement and efficient water management, while maintaining structural integrity and ease of maintenance across a wide temperature range.

Implementation Method 1

The spring means are arranged between sliding knob spring sections of the sliding knobs and plate spring sections of the plate-shaped element. The elastic deformation of the spring means takes place in the area between the sliding knob and the plate-shaped element.

AI summary

The invention relates to a sliding plate for a ski-jump facility, comprising the following features: a plate-shaped element (1) having an upper face that has sliding knob receptacles (11) which comprise sliding knob openings arranged in the plate-shaped element (1) and extending through the plate-shaped element (1); a plurality of sliding knobs (2) that are arranged in the sliding knob receptacles (11) in such a way that the sliding knobs (2) project out of the plate-shaped element (1); and spring means (3) that are designed in such a way that said spring means exert a restoring force on a relative movement between the sliding knobs (2) and the plate-shaped element (1). According to the invention, the spring means (3) are arranged between sliding knob spring sections (20) of the sliding knobs (2) and plate spring sections (10) of the plate-shaped element (1).
