Ski Jump Sliding Plate with Integrated Spring Suspension
Find Innovative SolutionsGenerate Solutions
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
Engineering Contradiction Analysis
1Reliability
If spring means are arranged between sliding knobs and plate-shaped element, then suspension functionality is improved, but device complexity increases
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.
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.
2Ease of repair
If detachable fastening means are used, then ease of repair is improved, but structural integrity may worsen
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.
3Ease of operation
If sliding knobs allow significant relative movement, then sliding behavior is improved, but suspension functionality may worsen
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.
