Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If multiple straight or curved tubes are welded connected or connected by connectors, then the trampoline frame structure is stable, but the installation is difficult and requires professionals

Engineering Contradiction:
Improveframe structure stabilityVSAvoidinstallation ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The frame is divided into multiple independent tube sections with standardized connection interfaces. Each section can be separately manufactured and transported, then assembled by end users through simple insertion and fixation operations, eliminating the need for professional installation while maintaining structural stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A specialized connector component is introduced as an intermediary between frame tube sections. This connector includes a insertion hole that receives a fixation component, providing a standardized and user-friendly connection mechanism that simplifies assembly while ensuring stable frame structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the frame size is fixed, then the manufacturing is simple, but it can't meet the requirements of different users

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidsize adjustability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The frame design allows dynamic reconfiguration by enabling users to add or remove tube sections and adjust the arrangement of flexible rods. The standardized connectors and hole patterns permit the frame to adapt to different size requirements while maintaining manufacturing simplicity through modular construction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The frame tubes and connectors are designed with universal interfaces that can accommodate different configurations and sizes. The same standardized components can be used to create various frame sizes and shapes, making the manufacturing process simple while providing versatility for different user needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If flexible rods are installed on traditional frame connectors, then the assembly is possible, but the distribution is uneven which affects the elasticity of bouncing pad

Engineering Contradiction:
Improveassembly feasibilityVSAvoidflexible rod distribution uniformity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The frame tube sections are pre-equipped with multiple holes at predetermined positions during manufacturing. This preliminary arrangement of holes ensures that flexible rods can be uniformly distributed when assembled, as the hole positions are pre-planned to achieve even spacing and optimal elasticity distribution across the bouncing pad.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If adjacent tubes are connected without prevention of rotation, then the assembly is simple, but harsh friction noise is generated during player jumping

Engineering Contradiction:
Improveassembly simplicityVSAvoidfriction noise
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The connector serves as an intermediary component that includes a fixation mechanism (such as a screw or clip) to prevent relative rotation between adjacent tubes. This simple addition eliminates harsh friction noise during use while maintaining assembly simplicity, as the rotation prevention feature is integrated into the standard connector design.

Inventive Principle:
Principle #24Intermediary (Mediator)
