Solution Overview

Problem

Existing mini-trampolines lack adjustable spring tension mechanisms, requiring users of different weights and abilities to use separate cords, leading to increased costs and inconvenience, and existing cords are not reusable once fatigued, resulting in premature replacement.

Innovation Solution

The implementation of adjustable bungee connectors and extenders with multiple tension adjustment positions, allowing the same cord to be reused across various users and extending its lifespan through re-tensioning, without the need for complete replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate cords are used for users of different weights and abilities, then each user can have optimal tension, but costs increase and inconvenience arises

Engineering Contradiction:

Improvetension adaptabilityVSAvoidnumber of cords

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent implements adjustable tension mechanisms that allow the same cord to dynamically change its tension characteristics. The cord includes multiple attachment points and adjustment mechanisms that enable users to modify tension levels according to their weight and ability, replacing the need for multiple fixed-tension cords with a single dynamically adjustable cord.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent creates a universal cord design that serves multiple users with different requirements. The cord incorporates features such as multiple attachment points, adjustable length, and variable tension capabilities, allowing one cord to perform the function previously requiring multiple specialized cords for different user types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If cords are replaced when fatigued, then safety is maintained, but lifespan is reduced and replacement costs increase

Engineering Contradiction:

ImprovesafetyVSAvoidcord lifespan

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent implements a cord recovery and rejuvenation system. When cords become fatigued, the system provides mechanisms to retrieve, re-tension, and restore the cords to their original performance characteristics. This includes adjustable tension mechanisms that can re-stretch and re-condition the elastic material, extending the cord's usable life significantly.

Inventive Principle:

Principle #34Discarding and recovering

Solution Approach 2:

The patent utilizes parameter changes in the cord's physical state to restore performance. By adjusting tension parameters, re-stretching the elastic material to specific elongation levels, and modifying the cord's mechanical properties through controlled deformation, the system rejuvenates fatigued cords and extends their operational lifespan while maintaining safety.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If adjustable tension mechanisms are added, then cord reusability increases, but device complexity increases

Engineering Contradiction:

Improvetension adjustabilityVSAvoidconnector complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the cord system into modular segments with standardized connection points. The adjustable tension mechanism is broken down into discrete components such as individual attachment points, separate adjustment mechanisms, and modular connector elements. This segmentation allows for easier manufacturing, assembly, and maintenance while providing the needed adjustability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediary components that simplify the connection between the cord and the rebounder frame. These intermediaries include adjustable connectors, attachment hardware, and tensioning devices that act as mediators between the user's adjustment actions and the cord's tension state, reducing the overall system complexity by providing standardized interfaces.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A trampoline with a frame has a rebounding mat that is tensioned to the frame with a plurality of flexible and cordlike linear elastic members. Preferably each cordlike elastic member is connected to the frame and the rebounding mat at one of two alternative positions to alter the tension. The alternative positions permit a tensioning process that extends the lifetime of elastic cords having a fabric sheath. This independent tension of each elastic member is via connector member that grips the rebounding mat but also grasps opposing the ends of the elastic members as well as central portion thereof so that two segment of the cord between each end and the central portion are preferably wrapped around the trampoline frame.
