Solution Overview

Problem

Existing exercise swings lack the ability to provide controlled, gentle resistance and support for rehabilitation after injury, failing to effectively aid in muscle recovery and progress tracking.

Innovation Solution

A swing with a variable resistance mechanism, supportive seating, and data tracking capabilities, allowing users to adjust resistance and monitor their progress, featuring a seat with back, arm, and leg rests, and a safety barrier with sensors for user safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing exercise swings are used, then basic swinging motion is provided, but they lack controlled resistance and support for rehabilitation after injury

Engineering Contradiction:
Improverehabilitation effectivenessVSAvoidcontrolled gentle exercise
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the resistance adjustable rather than fixed. The resistance mechanism can be dynamically modified to provide controlled gentle exercise, allowing the swing to adapt to different rehabilitation stages and user needs, thereby resolving the contradiction between reliability for rehabilitation and ease of operation for controlled exercise

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the resistance parameter from fixed to variable. By allowing resistance to be adjusted, the system can provide the controlled gentle exercise needed for rehabilitation while maintaining reliability. This parameter change enables the swing to deliver both basic motion and therapeutic control

Inventive Principle:
Principle #35Parameter changes

2Reliability

If resistance mechanism is added to provide controlled exercise, then rehabilitation effectiveness improves, but device complexity increases

Engineering Contradiction:
Improverehabilitation effectivenessVSAvoidresistance mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical resistance systems with a simpler mechanism. Instead of using elaborate mechanical components, the invention employs a more straightforward resistance adjustment system that achieves rehabilitation effectiveness without excessive complexity, resolving the contradiction between reliability and device complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If full seat with back, arm and leg rests is provided, then user support and comfort improve, but device complexity and cost increase

Engineering Contradiction:
Improveuser support and comfortVSAvoidseat structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the support structure into distinct functional components: back rest, arm rests, and leg rests. Each segment provides specific support tailored to different body parts, improving user comfort and ease of operation during rehabilitation exercises while maintaining manageable device complexity through modular design

Inventive Principle:
Principle #1Segmentation

AI summary

An exercise swing comprising: a seat (108); an axle (102); at least one swingable member ( 106) having a first end attached to said seat and a second end connected via a pivot (104) to said axle; and a resistance adjuster (120) for varying the resistance of said pivot to back-and-forth swinging motion of the swingable member about the pivot, and the exercise swing arranged so as to allow the entire body of a user, with the user seated on the seat, to swing back-and-forth through an arcuate path.
