Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fitness and rehabilitation equipment are affected by gravity, causing stress on the torso's coupling elements and leading to wear and potential damage, with existing anti-gravity solutions being complex and costly or lacking sufficient safety and flexibility.
Innovation Solution
A device with anti-gravity and suspension features, including a base with rails, a torso support unit that adjusts vertically along the rails, and a torso-wearing unit with coupling elements, allowing the torso to be lifted and suspended, reducing lower limb stress while ensuring user safety during exercise or rehabilitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional fitness equipment is used, then the equipment structure is simple and cost-effective, but the torso coupling elements are subjected to gravity stress causing wear and potential damage
Solution Approach 1:
The patent applies the anti-weight principle by using a buoyancy chamber filled with gas (air or helium) to generate an upward buoyant force that counteracts the downward gravitational force on the user's torso. This reduces the stress on coupling elements during exercise while maintaining a relatively simple device structure compared to other anti-gravity solutions.
2Object-affected harmful factors
If differential air pressure system is used to counteract gravity, then the anti-gravity effect is achieved, but the device structure becomes complex and manufacturing cost increases
Solution Approach 1:
The patent uses a simplified anti-weight approach by employing a buoyancy chamber filled with gas rather than a complex differential air pressure system. The gas-filled chamber provides sufficient buoyant force to counteract gravity during exercise, achieving the anti-gravity effect with reduced structural complexity and lower manufacturing costs.
Solution Approach 2:
The patent opt s for a cost-effective solution by using a gas-filled buoyancy chamber instead of expensive differential air pressure systems with multiple sensors, valves, and compressors. This approach prioritizes functional effectiveness while significantly reducing device complexity and manufacturing cost.
3Object-affected harmful factors
If torso is suspended to reduce gravity stress, then coupling elements are protected, but user safety may be compromised without proper support
Solution Approach 1:
The patent incorporates safety straps and support mechanisms that are pre-configured to catch and support the user in case of failure or loss of balance. These safety features provide beforehand cushioning, ensuring user safety is maintained even when the torso is suspended to reduce gravity stress on coupling elements.
Solution Approach 2:
The patent uses safety straps and support structures as intermediary elements between the user and the suspension system. These intermediaries provide additional safety assurance, allowing the torso to be suspended for protecting coupling elements while maintaining user safety through redundant support mechanisms.

AI summary
A device with anti-gravity suspension is provided, comprising: a base, a torso support unit and a torso-wearing unit; wherein, the base is provided with two rails erected on two opposite sides; the torso support unit is connected to and movable up and down along the two rails, the torso support unit has a torso-holding portion for accommodating a torso, and the torso-holding portion is acted on by at least one actuating element disposed on the torso support unit to move up and down vertically; the torso-wearing unit is worn on the torso of a user, and a second coupling element disposed on the torso-wearing unit is connected to a first coupling element disposed on the torso-holding portion. When the user is held by the torso-holding portion, the torso weight load on the lower limbs can be reduced.
