Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barbell supports are bulky, making them difficult to store compactly and can be unstable and damage floors if not installed correctly, due to out-of-square corners or uneven surfaces.
Innovation Solution
A wall-mountable barbell rack with hinged poles that rotate between a use position and a rest position, allowing for compact storage and secure installation, featuring C- or U-shaped uprights for housing poles and a locking system to prevent accidental movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional barbell supports are used, then they provide stable support for barbell exercises, but they require significant 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, allowing them to move between a canonical use position and a rest position. This dynamic transformation enables the structure to change its spatial footprint from a large ground-based configuration to a compact wall-mounted configuration, resolving the contradiction between storage space requirements and structural stability.
Solution Approach 2:
The patent transitions the barbell support from a ground-based three-dimensional structure occupying horizontal space to a wall-mounted structure utilizing vertical wall space. By fixing the supports to the wall and rotating them into a plane against the wall, the invention moves the structure into another dimension (from horizontal floor occupation to vertical wall occupation), significantly reducing the space required for storage while maintaining structural integrity during use.
2Volume of moving object
If the poles are made rotatable to save space, then compact storage is achieved, but the poles may slide on the floor or be lifted off the floor, making the structure unstable
Solution Approach 1:
The patent applies preliminary action by providing adjustment means that allow the horizontal position of the poles to be adjusted and fixed before use. This preliminary positioning ensures that the poles are correctly aligned and secured to the wall at the proper distance, preventing them from sliding on the floor or being lifted off during operation. The adjustment mechanism is set up in advance to eliminate instability issues.
Solution Approach 2:
The patent replaces the conventional mechanical connection system (where poles directly contact the floor for stability) with a wall-mounted hinging system. Instead of relying on floor contact for structural reliability, the poles are hinged to vertical supports that are fixed to the wall, transferring the stability requirement from the floor-pole interface to the wall-support interface, which is more reliable and prevents sliding or lifting issues.
3Volume of moving object
If the poles are positioned close to the wall for compact storage, then space is minimized, but tensile pulling forces are exerted on the wall supports when load is applied
Solution Approach 1:
The patent applies preliminary action by providing adjustment means that allow the horizontal position of the poles to be adjusted and fixed before use. This preliminary positioning ensures that the poles are correctly aligned and secured to the wall at the proper distance, preventing them from sliding on the floor or being lifted off during operation. The adjustment mechanism is set up in advance to eliminate instability issues.
Solution Approach 2:
The patent applies parameter changes by allowing the horizontal distance between the poles and the wall to be adjusted. The adjustment means enable the poles to be positioned at an optimal distance from the wall that balances compact storage with structural stability, reducing excessive tensile forces on the wall supports while maintaining sufficient distance for proper barbell support during exercise.
