Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Indoor exercise equipment lacks the ability to provide adequate assistance and safety for elderly individuals or rehabilitation patients who cannot bear heavy weights on their lower limbs, necessitating additional support for correct exercise execution and accident prevention.
Innovation Solution
A suspension auxiliary device with adjustable steel cables and a controller to support user weight, reducing lower limb load-bearing capacity, ensuring safety and enabling exercise or rehabilitation on movable exercise apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If indoor exercise equipment is designed for general users, then fitness training capability is provided, but it cannot support elderly or rehabilitation patients who cannot bear heavy weights on lower limbs
Solution Approach 1:
The patent introduces a suspension auxiliary device as an intermediary between the exercise equipment and the user. This device includes a suspension belt that wraps around the user's torso and connects to a motorized lifting mechanism, which acts as a mediator to support the user's weight and reduce the burden on lower limbs during exercise
Solution Approach 2:
The suspension auxiliary device employs a motorized lifting mechanism with adjustable lifting force and speed control. The motor can dynamically adjust the suspension force based on user needs, and the steel cables can be extended or retracted to change the suspension height, providing dynamic adaptation to different exercise stages and user requirements
2Reliability
If suspension assistance is added for elderly or rehabilitation patients, then safety and support are improved, but device complexity increases
Solution Approach 1:
The motorized lifting mechanism serves multiple functions: it provides suspension support, adjusts cable length, controls lifting speed, and regulates suspension force. The controller integrates multiple control functions including speed regulation, force adjustment, and emergency stopping, making the system multi-functional while appearing as a unified device
Solution Approach 2:
The patent combines the suspension belt, steel cables, motorized lifting mechanism, and controller into an integrated suspension auxiliary device. The control unit merges speed control, force adjustment, and emergency stop functions into a single control interface, reducing operational complexity despite the enhanced safety features
3Adaptability or versatility
If steel cable length is made adjustable to accommodate different users, then adaptability is improved, but control complexity increases
Solution Approach 1:
The motorized lifting mechanism automatically adjusts the steel cable length based on controller commands. The user simply needs to operate the controller, and the system self-adjusts the cable extension or retraction, eliminating the need for manual cable length adjustment and simplifying the user experience

Implementation Method 1
a transmission mechanism 2 mounted on the base 1 and having at least one hook 241 connected thereon to hook a sling carrier 4 of a user 6
Implementation Method 2
the motor 21 drives the two steel cables 24 to extend or retract, so that a length of the two steel cables 24 is adjustable
Implementation Method 3
the suspension auxiliary device 10 hangs and supports a part or a whole weight of the user 6
Implementation Method 4
the two steel cables 24 rolled on the two cable pulleys 23, wherein two outer ends of the two steel cables 24 are extended along the two spaced rods 15 of the base 1

AI summary
A suspension auxiliary device is applicable for a movable exercise apparatus in a fixed state and contains a base. The base includes two spaced rods, a coupling column, an end of an adjustment column is rotatably connected with the coupling column, and the other end of the adjustment column is rotatably connected on the base. The adjustment column is pulled via a fixing bolt so as to manually adjust a vertical moving position of the two spaced rods, and the fixing bolt is fixed so that the two spaced rods are fixed on a predetermined position. The base includes a transmission mechanism which has two hooks, such that the suspension auxiliary device hangs and supports a part or a whole weight of the user, and the users whose lower limbs cannot bear a heavy weight can perform exercise or rehabilitation training on a movable exercise apparatus by themselves.
