Hitch-Mounted Workout Frame With Ground Support Against Suspension Bounce
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted workout devices lack additional support, causing them to move with the vehicle's suspension, making them unstable for exercise.
Innovation Solution
A hitch mountable workout apparatus with a vertical main shaft, adjustable bottom support, and pull-up bar, which engages a trailer hitch and includes a support foot to stabilize on the ground, preventing forward-backward pitch and allowing for various exercises like pull-ups, dips, and push-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the workout device is mounted to the trailer hitch without additional support, then the device is portable and easy to install, but the device moves with the vehicle suspension and becomes unstable during exercise
Solution Approach 1:
A support foot is introduced as an intermediary element between the workout device and the ground. This support foot provides additional contact points with the ground, creating a stable triangular support structure that prevents the device from moving with vehicle suspension while maintaining easy hitch-based installation
Solution Approach 2:
The support foot extends the support structure into a new dimension by contacting the ground directly, rather than relying solely on the hitch connection point. This creates a three-point support system (two hitch mounts plus one support foot) that stabilizes the device against suspension movement
2Adaptability or versatility
If the workout device is mounted to the trailer hitch, then the device is portable and can be easily attached to vehicles, but the device lacks additional support causing it to bounce and move with vehicle suspension
Solution Approach 1:
The support foot acts as a mediator that transfers load from the workout device to the ground independently of the hitch connection. This creates a parallel support path that enhances reliability under exercise loads while preserving the portable hitch-mounted design
Solution Approach 2:
The support foot provides beforehand cushioning by preemptively contacting the ground to prevent bounce and movement before exercise forces are applied. This pre-stabilization ensures reliable performance during high-load exercises
3Adaptability or versatility
If the workout device allows forward-backward pitch movement, then the device can accommodate vehicle suspension movement, but the device becomes unstable and cannot support effective exercise performance
Solution Approach 1:
The support foot serves as a mediator that selectively accommodates certain movements while preventing others. It allows the device to remain attached to the moving hitch but prevents forward-backward pitch by providing ground contact that anchors the device during exercise

AI summary
A hitch mountable workout apparatus for providing a portable sturdy workout apparatus includes a hitch mount having a hitch end and a shaft end. The hitch end selectively engages a trailer hitch. A vertical main shaft has a shaft back side attached to the shaft end of the hitch mount, a shaft front side, a shaft left side, a shaft right side, a shaft top end, and a shaft bottom end. A bottom support has a support tube slidably engaged within the shaft bottom end and a support foot coupled to the support tube. The bottom support is adjustable to rest the support foot on the ground while the hitch mount is engaged with the trailer hitch. A pull-up bar has pull-up tube slidably engaged within the shaft top end, a cantilever coupled to the pull-up tube, and a crossbar coupled to the pull-up tube.
