Door Frame Suspension Gym Bracket and Rod System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door-frame attached exercise equipment lacks stability, adjustability, and durability, often causing instability during use, potential injury from broken rubber cords, and is cumbersome to store and remove.
Innovation Solution
A suspension gym system with permanently secured brackets to the door frame, featuring an adjustable length rod, rotatable central ring, and adjustable straps with locking mechanisms, along with rubber grip sleeves and multi-purpose rings for versatile exercise options, ensuring stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If devices attach to door frame via friction or pressure fit, then installation is simple, but stability during vigorous exercise is insufficient
Solution Approach 1:
The mounting system is divided into separate components: brackets that attach to the door frame and a rod that suspends the exercise equipment. This segmentation allows the brackets to provide secure mounting while keeping the equipment removable and adjustable.
Solution Approach 2:
The brackets are permanently secured to the door frame before use, establishing a stable foundation in advance. This preliminary action ensures that the mounting structure is ready to support vigorous exercise without requiring complex assembly during actual use.
2Ease of operation
If rubber cords are used for suspension, then flexibility and comfort are improved, but risk of breaking and causing injury increases
Solution Approach 1:
The suspension system combines rubber cords with metal components (rod, brackets, rings). This composite approach provides the flexibility and comfort of rubber while the metal elements provide strength and durability, eliminating the risk of complete failure that occurs with pure rubber cords.
Solution Approach 2:
The system includes multiple support points and distribution mechanisms that prevent any single component from bearing excessive load. The brackets, rod, and multiple rings work together to distribute forces, preventing breakdown even under vigorous use.
3Stability of the object's composition
If devices are made heavy for stability, then stability during use is improved, but ease of removal and storage deteriorates
Solution Approach 1:
The equipment is divided into a heavy bracket component that remains permanently mounted for stability, and a lighter rod and equipment portion that can be easily removed and stored. This segmentation allows the system to be stable during use but easy to remove when not in use.
Solution Approach 2:
The removable rod and equipment components are extracted from the permanent bracket structure. This allows the heavy, stable brackets to remain installed while the lighter, removable portions can be easily stored, separating the functions of stability and portability.
4Ease of manufacture
If fixed-length straps are used, then manufacturing is simple, but adaptability for various exercises is limited
Solution Approach 1:
The straps are designed with adjustable length mechanisms that allow users to modify the strap length according to different exercise requirements. This dynamic adjustability provides versatility for various exercises while maintaining relatively simple manufacturing through the use of standard adjustment mechanisms.

AI summary
A piece of exercise equipment or gym that is secured to either side of a door frame via brackets that are permanently secured to the sides of the door frame across the upper end of a doorway. The gym has an adjustable length rod that is removably suspended between the brackets. A rotatable ring or connection point secured centrally on the rod supports two adjustable length straps. The free end of each strap is provided with a ring to which handles or stirrups can be attached. Also, the rod itself has rubber grips on it and is provided with additional multi-purpose rings where handles or stirrups can be attached.
