Training Device Foot Element Support Web Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training devices face issues where the side walls can no longer maintain sufficient spacing from the base when subjected to higher loads, leading to potential damage such as chipping or cracking when the base is hard, like concrete.
Innovation Solution
Incorporating a support web radially and axially offset from a circumferential annular bead to prevent the erection head from migrating into the base body, combined with a larger diameter erection head and insertion/holding shaft for stable support and air passage to relieve pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the foot plugs are made of rubber to be softer and non-destructively flexible, then the foot plugs can adapt to the base surface, but the side walls may still chip, crack, or be damaged when struck or impacted by the base under heavy loads
Solution Approach 1:
The patent applies beforehand cushioning by providing a groove in the base body that receives a cushioning element (such as a rubber strip or foam material). This cushioning element is positioned between the side wall and the base surface before any impact occurs, preventing direct contact and potential damage to the side wall while maintaining the flexibility and adaptability of the foot plugs.
2Strength
If the erection head diameter is increased to provide sufficient support surface, then the support capability improves, but the device complexity increases
Solution Approach 1:
The patent merges the support function with the existing foot element structure by integrating the erection head into the foot plug assembly. The erection head is formed as part of the foot element, combining the spacing function and support function into a single integrated component, thereby providing sufficient support surface area without significantly increasing overall device complexity.

AI summary
A training device (1) for placement on a surface, comprising a base body (2) made of plastic with a bottom and a top, wherein foot elements (3) for placement on the surface are arranged or formed on the bottom, wherein a footplate (4) is arranged or formed on the top, wherein side walls (5) project towards the surface on the bottom, and wherein the foot elements (3) are arranged in corner regions (16) of the base body (2) to space the side walls (5) away from the surface, is designed and further developed with regard to the task of designing and further developing a training device of the type mentioned above in such a way that, even under higher loads on its footplate, the side walls remain as undamaged as possible or sufficiently spaced away from a surface, characterized in that a support rib (6) for a mounting head (7) of a foot element (3) is arranged or formed in at least one corner region (16).the mounting head (7) rests at least partially against a support surface (8) facing away from the base, wherein the support web (6) is set inwards relative to an outwardly projecting and/or outwardly convexly curved annular bead (15) which surrounds the support web (6) and/or the mounting head (7) around its circumference and/or in a laterally external corner zone (17).
