Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for sports equipment, such as ceiling hooks and rail systems, require complex procedures for securely locking and changing the position of runners, making it difficult to easily attach and detach sports equipment.
Innovation Solution
A fastening device featuring a rail with parallel side cheeks and grooves, and a holding element with thorns that securely engage with the grooves for easy positioning and locking, allowing for simple change and secure fixation of sports equipment on various surfaces like ceilings and walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locking mechanisms (twist-lock latches or locking screws) are used to secure the slider to the rail, then the locking reliability is improved, but the operational complexity and time required for positioning and locking increase
Solution Approach 1:
The patent replaces complex mechanical locking mechanisms (twist-lock latches, locking screws requiring rotational movement) with a simplified system where the slider is locked to the rail by frictional engagement using locking screws that only require simple tightening motion, substituting complex mechanical locking with friction-based retention
Solution Approach 2:
The slider design allows the locking screws to automatically engage and lock the slider to the rail through frictional engagement when the slider is positioned at a hole, eliminating the need for additional locking actions or complex operational sequences
2Ease of manufacture
If ceiling hooks are used as fastening devices, then the installation simplicity is improved, but the ability to easily change position is worsened
Solution Approach 1:
The system segments the positioning function into discrete locations marked by holes at regular intervals on the rail, allowing the slider to be easily repositioned to predefined locations by simply moving it along the rail and engaging with the next hole, rather than requiring reinstallation of entire ceiling hooks
Solution Approach 2:
The rail system acts as an intermediary between the ceiling hooks and the slider, providing a guided pathway that allows easy repositioning while maintaining secure attachment, mediating between the fixed ceiling installation and the movable slider
3Measurement precision
If precision positioning is required for the slider on the rail, then the positioning accuracy is improved, but the operational time and complexity increase
Solution Approach 1:
The rail is pre-marked with holes at regular intervals at predefined locations, preparing the positioning locations in advance, so the slider can be quickly and accurately positioned by simply engaging with the pre-marked holes without requiring measurement or adjustment during operation

AI summary
The invention relates to a fastening device, in particular for suspending a sports device, comprising: - a fastening element, - a rail with two parallel side flanges connected to each other by means of a first connecting surface along a longitudinal extension of the rail, which is oriented open towards the ceiling, wherein the rail has at least one pair of grooves consisting of two grooves arranged opposite each other on the side flanges of the rail, - and a retaining element with two parallel side flanges connected to each other by means of a second connecting surface along a longitudinal extension of the retaining element, which is oriented open towards the ceiling, wherein the longitudinal extension of the retaining element is shorter than the longitudinal extension of the rail, and wherein the retaining element has at least one pair of pins consisting of two pins arranged opposite each other on the side flanges of the retaining element, wherein the pins are arranged facing each other.wherein the pins correspond to the grooves in such a way that they lock into the grooves to fix a position of the retaining element on the rail.
