Wall-Mounted Barbell Rack with Hinging Poles for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barbell supports are bulky, making them difficult to store compactly and can be unstable due to out-of-square installations, leading to issues like pole sliding or lifting off the floor, and excessive tensile force on wall supports when loaded.
Innovation Solution
A wall-mountable barbell rack with hinging poles that rotate between a use position and a rest position, allowing for compact storage while maintaining stability through parallel and adjustable pole configurations that contact the floor, and a locking system to prevent accidental movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the barbell rack uses a conventional base and four vertical supports structure, then it provides stable support for barbell, but it requires significant amount of space and cannot be stored compactly
Solution Approach 1:
The patent applies the dynamics principle by making the vertical supports rotatable around a vertical hinge axis. The supports can rotate between a canonical use position (providing stable barbell support) and a rest position (where they are on or near the wall, minimizing overall dimensions). This dynamic transformation allows the same structure to fulfill both stability and compact storage requirements at different times.
2Volume of moving object
If the poles are made rotatable between use position and rest position, then compact storage is achieved, but the poles may slide on the floor or be lifted off the floor causing instability
Solution Approach 1:
The patent applies preliminary anti-action by providing means for hinging each pole to the corresponding upright to prevent unwanted movement. The hinge connection ensures that the poles remain properly positioned during rotation and do not slide on the floor or lift off unexpectedly. This preventive measure counteracts the potential harmful effects of the rotatable design before they can occur.
Solution Approach 2:
The patent uses the hinge as an intermediary element between the pole and the upright. The hinge acts as a mediator that controls the rotation movement, allowing the pole to rotate smoothly while maintaining proper alignment and preventing uncontrolled sliding or lifting. The hinge mediates the interaction between the pole and floor, ensuring stable operation during both use and storage positions.
3Volume of moving object
If the poles are positioned close together in rest position, then compact storage is achieved, but tensile pulling force is exerted on the wall supports when load is applied
Solution Approach 1:
The patent applies dynamics by designing the support structure to be in different configurations based on usage state. In the rest position, the poles are close together for compact storage. When a load is applied during use, the structure dynamically transitions to the use position where the poles are spaced apart, which reduces the tensile pulling force on the wall supports. The dynamic reconfiguration allows the system to optimize for either compactness or force distribution depending on the operational state.

The solution provides a robust, reliable, and space-saving barbell rack that is easy to install and stable under load, with poles that fold within the uprights for compact storage and a locking mechanism to prevent accidental falling.
Implementation Method 1
means for hinging each pole to the corresponding upright in such a way that each pole is movable between a use position, in which it is at a maximum distance from the corresponding upright, and a rest position, in which it is at a minimum distance from the corresponding upright
