Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports equipment, such as skis, face challenges in providing improved driving comfort and guiding properties due to complex and heavy distribution devices that compromise weight and efficiency.
Innovation Solution
A sports device with a distribution system featuring pivotally connected swivel arms and an adjustable pivot axis, utilizing an elastically deformable spring or damping element to enhance stability and damping, allowing for better load distribution and directional control through eccentrically positioned joints and spacers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a complex distribution device with multiple parts is used to improve load distribution and guiding properties, then the guiding properties and directional stability are improved, but the device weight and complexity increase significantly
Solution Approach 1:
The patent combines the carrier support function and the elastic restoring element into an integrated assembly where the spring element is directly mounted on the carrier, eliminating the need for separate complex distribution devices while maintaining load distribution and guiding properties
Solution Approach 2:
The carrier is designed to perform multiple functions: it supports the user's boot, provides elastic restoration through the integrated spring element, and maintains directional stability, thereby reducing the need for additional specialized components
2Stability of the object's composition
If a tall distribution device is used to improve guiding properties, then directional stability is enhanced, but the device height increases which negates the advantages
Solution Approach 1:
The patent transitions from a vertical arrangement (tall device) to a lateral arrangement where swivel arms extend sideways from the carrier, achieving directional stability through lateral spacing rather than vertical height
3Device complexity
If the pivot axis position is fixed to simplify the structure, then device complexity is reduced, but adaptability to different skiing conditions and user preferences is limited
Solution Approach 1:
The patent introduces an adjustable pivot axis mechanism that allows the pivot position to be changed by the user, transforming a static fixed structure into a dynamic adjustable one that adapts to different skiing conditions and user preferences while maintaining reasonable structural simplicity

AI summary
The invention relates to a sporting device (1), comprising a carrier (3) for a coupling device (25) for accommodating a user and comprising at least one distributing device (2) for the loads and/or forces to be transmitted to the sporting device (1), which at least one distributing device (2) connects the carrier (3) to the sporting device (1) by means of a joint assembly, which has at least one pivoting arm (4, 5; 6, 7), which is pivotably connected, in each case by means of a joint (8, 9; 10, 11), to the sporting device (1) at one arm end of the pivoting arm and to the carrier (3) at the other arm end of the pivoting arm. The carrier (3) can be moved from a starting position to a balancing position, in which the carrier is brought closer to the sporting device (1), against the restoring force of at least one elastic restoring element. The sporting device (1) according to the invention is characterized in that the at least one restoring element is an elastically deformable spring element (12; 13), which is retained on the carrier (3) at one end and on the sporting device (1) at the other end.
