Exercise Platform Pivoting Support with Spindle Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise steps are limited to horizontal orientations and require additional wedge-shaped risers for angled configurations, which are cumbersome, costly, and inefficient in terms of storage and use, as they need to be swapped in and out for different exercises.
Innovation Solution
An exercise apparatus with a platform that can pivot between horizontal and sloped orientations using detachable supports with spindle engagement elements, allowing for adjustable height and angle configurations without the need for additional components, providing secure support and multiple use scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wedge-shaped risers are added to enable sloped platform configuration, then the platform can be securely supported in angled orientation, but the device complexity increases and additional components are required
Solution Approach 1:
The spindle engagement element integrates both the support function and the wedging function into a single component. The inclined surface of the engagement element automatically provides the wedging action when the platform is positioned, eliminating the need for separate wedge-shaped risers while maintaining secure support in both horizontal and sloped configurations
Solution Approach 2:
The detachable support with spindle engagement element serves multiple functions: it provides vertical support, enables angular adjustment through the inclined engagement surface, and secures the platform through the pivotal connection. This single component replaces multiple specialized components (vertical supports + wedge risers) required by conventional designs
2Reliability
If wedge-shaped risers are provided for sloped exercises, then secure support is achieved, but storage and transit volume increases
Solution Approach 1:
The support and engagement element are combined into one integrated component that provides both support and securing functions. The inclined surface of the engagement element inherently provides the wedging action, eliminating the need for separate wedge risers that would occupy additional storage space
Solution Approach 2:
The detachable support design allows the engagement element to be reused across multiple platforms and configurations. Instead of discarding or storing separate wedge risers for each platform, the integrated engagement element remains part of the support structure, reducing overall equipment volume
3Adaptability or versatility
If additional wedge risers are included for angled exercises, then sloped configuration is enabled, but manufacturing cost increases
Solution Approach 1:
The support and engagement element are manufactured as a single integrated component, eliminating the need to separately manufacture and assemble wedge risers. This reduces part count, simplifies the supply chain, and lowers manufacturing costs while maintaining the ability to provide both horizontal and sloped exercise configurations
Solution Approach 2:
The integrated support with inclined engagement element serves as a universal component that enables both horizontal and sloped configurations without requiring additional specialized parts. This multi-functionality reduces the total bill of materials and manufacturing complexity
4Ease of operation
If conventional detachable supports are used, then platform height is adjustable, but the platform becomes unstable when angled
Solution Approach 1:
The engagement element features an asymmetric inclined surface that creates a self-locking effect when the platform is angled. The geometry of the inclined surface ensures that the platform is securely held in both horizontal and sloped positions, preventing instability that would occur with symmetric conventional supports

AI summary
An exercise apparatus includes a platform for supporting a person during exercise. A first support is provided that is arranged to support a first end of the platform at an elevated position. A second support is arranged to engage with the platform at a second end to support the second end of the platform at an elevated position. The second support is also movable to vary the height of the second end. The first support includes pivotal engagement elements that are configured for engagement with corresponding pivotal engagement elements of the platform. In use, when pivotal engagement elements of the platform are engaged with and supported on the pivotal engagement elements of the first support, the platform is able to pivot relative to the first support. The height of the second end is varied while holding and retaining the platform on the support.
