Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing rebound training devices, such as trampolines, often cause jarring effects on the feet, ankles, shins, knees, and lower back due to the lack of handholds for balance and the possibility of awkward landings, which can lead to injuries, especially for older or disabled individuals who may require low-impact aerobic exercise.

Innovation Solution

A rebound training device with a frame and a footboard suspended by resilient elements, allowing adjustable vertical travel and grip options, including hand grips and a large, stable footboard that can be rotated for enhanced stability and comfort, enabling users to modify the intensity of their workout and maintain balance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a trampoline is used for rebounding exercise, then aerobic exercise benefits are achieved, but jarring effects on feet, ankles, shins, knees, and lower back occur due to lack of handholds and possibility of awkward landings

Engineering Contradiction:

Improveaerobic exercise intensityVSAvoidimpact on feet, ankles, shins, knees, and lower back

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a frame structure with handholds as an intermediary element between the user and the rebounding surface. These handholds serve as a mediator that allows users to control their balance and landing position, thereby reducing the harmful impact effects on the body while maintaining aerobic exercise benefits

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The resilient elements (springs) are designed to provide gradual deceleration upon landing. The spring constant and arrangement are configured to cushion the impact before it reaches the user's body, reducing jarring effects on feet, ankles, shins, knees, and lower back while still allowing effective rebounding exercise

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Productivity

If the footboard is made flexible to allow rebounding motion, then aerobic exercise benefits are achieved, but the user's feet may leave the flexible surface causing awkward landings and potential injury

Engineering Contradiction:

Improveaerobic exercise benefitsVSAvoidsafety against awkward landings and injury

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The footboard is designed with non-uniform properties - it has resilient elements at certain locations to allow rebounding motion while maintaining rigidity in other areas to prevent feet from leaving the surface. This local differentiation of flexibility and rigidity ensures both exercise effectiveness and safety

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If handholds are added to the frame to prevent jarring effects, then impact on user is minimized, but device complexity increases

Engineering Contradiction:

Improveimpact effects on userVSAvoidframe structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The frame structure serves multiple functions simultaneously: it provides structural support for the resilient elements, offers handholds for balance and impact reduction, and defines the overall device geometry. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving impact minimization

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A rebound training device includes a frame, a footboard, and a plurality of resilient elements extending between and attached to the frame and the footboard to support the footboard above a supporting surface. A user standing on the footboard manually effects repeated vertical bouncing movement between upper and lower positions. The distance traveled by the footboard, the effort required to effect movement, and the stability thereof may be modified by selectively modifying the number, the length, the position, or the elasticity of the resilient members.
