Solution Overview

Problem

Existing trampoline manufacturing methods are time-consuming and labor-intensive due to the use of weaved ropes or cords to secure the top panel to the main body.

Innovation Solution

The trampoline features a top panel attached to a gas-filled, toroidal main body using RF welding or heat sealing, with a laminated polyvinyl chloride top panel and matching material for the main body, forming a single piece with venting holes to prevent entrapment, and a manufacturing method that sizes the top panel according to the central opening for quick assembly without gaps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If weaved rope or cord is used to secure the top panel to the main body, then the attachment method is simple and reliable, but the manufacturing process becomes time-consuming and labor-intensive

Engineering Contradiction:
Improveattachment reliabilityVSAvoidmanufacturing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical weaved rope or cord attachment system with a thermal bonding system (heat sealing or RF welding). This substitution eliminates the need for manual weaving operations while maintaining secure attachment through thermal fusion of the material layers, thereby significantly improving manufacturing speed and productivity.

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

Solution Approach 2:

The patent changes the attachment mechanism from mechanical (rope/cord weaving) to thermal (heat sealing or RF welding). By controlling parameters such as temperature, pressure, and bonding time during the thermal process, reliable attachment is achieved without the labor-intensive manual weaving operations, thus resolving the contradiction between reliability and productivity.

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If weaved rope or cord is used to secure the top panel to the main body, then the attachment method is traditional and straightforward, but the manufacturing process becomes labor-intensive

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidmanufacturing efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical weaving process with an automated thermal bonding process. Heat sealing or RF welding can be performed through automated machinery, eliminating manual labor while maintaining manufacturing simplicity. This substitution directly addresses the contradiction by removing labor-intensive operations while preserving ease of manufacture.

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

Solution Approach 2:

The thermal bonding process allows the material itself to bond through heat or electromagnetic energy, eliminating the need for manual weaving operations. The material's own properties (thermal conductivity, melting point) are utilized to create the bond, making the process self-service and highly efficient, thus resolving the contradiction between ease of manufacture and productivity.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If traditional attachment methods are used, then the manufacturing process is straightforward, but gaps may remain where the top panel and main body meet

Engineering Contradiction:
Improvemanufacturing straightforwardnessVSAvoidattachment precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent replaces the mechanical weaving method with thermal bonding (heat sealing or RF welding). This substitution creates a continuous bond between the top panel and main body without gaps, as the thermal process fuses the materials together seamlessly. The manufacturing remains straightforward while achieving high precision attachment, thus resolving the contradiction.

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

Solution Approach 2:

By changing from mechanical attachment to thermal bonding, the patent controls parameters such as temperature, pressure, and bonding duration to achieve precise, gap-free attachment. These parameter controls ensure that the top panel and main body bond seamlessly, eliminating gaps while keeping the manufacturing process straightforward, thus resolving the contradiction between ease of manufacture and manufacturing precision.

Inventive Principle:
Principle #35Parameter changes
