Solution Overview

Problem

Existing trampoline enclosure and pad systems do not provide a sufficiently softened and safe netting configuration to prevent user injuries and entrapments effectively.

Innovation Solution

A trampoline system featuring a double-layered enclosure net with larger outside net openings and smaller inside net openings, a pad system with a wall pad and buttress pad configuration, and an optional spring cover to enhance safety and prevent user entrapment, along with a unique net weaving structure and attachment mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single-layer enclosure net is used, then the device complexity is reduced, but the safety and entrapment prevention capability deteriorates

Engineering Contradiction:
Improvesafety and entrapment preventionVSAvoidenclosure net structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The enclosure net is divided into two distinct layers: an outer net with larger openings for general enclosure and an inner net with smaller openings for entrapment prevention. This segmentation allows each layer to perform its specific safety function while maintaining overall system reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner net with smaller openings is nested within the outer net structure. This nested configuration allows the finer mesh to be positioned inside the larger mesh, creating a dual-stage retention system where the inner net prevents entrapment while the outer net provides structural support.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If larger net openings are used, then the ease of operation and user comfort is improved, but the risk of finger entrapment increases

Engineering Contradiction:
Improveuser comfortVSAvoidfinger entrapment risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Different net opening sizes are applied to different functional requirements: the outer net has larger openings to provide user comfort and ease of operation, while the inner net has smaller openings specifically at locations where entrapment prevention is critical. This local differentiation of net quality addresses both comfort and safety requirements.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The inner net with smaller openings acts as an intermediary layer between the user and the outer net structure. It mediates the conflict between large opening comfort and small opening safety by providing an additional protective barrier that prevents finger entrapment while allowing the outer net to maintain its larger, more comfortable openings.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a pad system with buttress pad is used, then the cushioning effect upon impact is improved, but the device complexity increases

Engineering Contradiction:
Improvecushioning effectVSAvoidpad system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The buttress pad is pre-positioned and pre-configured in the pad system before impact occurs. It is installed at specific angles and locations to provide immediate cushioning support when impact happens, eliminating the need for complex active adjustment mechanisms during impact events.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The buttress pad is configured at specific angles (e.g., 45-degree angles) relative to the wall pad, creating a geometric arrangement that optimizes force distribution and cushioning effectiveness. This angular configuration provides enhanced protection while maintaining relatively simple structural implementation.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A trampoline comprising a trampoline frame having legs. The trampoline frame has a trampoline frame horizontal portion. A trampoline bed is suspended across the trampoline frame horizontal portion. Springs extend between the trampoline frame and trampoline bed. An enclosure is connected to the trampoline frame. The enclosure has an enclosure upper support. The enclosure supports an enclosure net. A pad system covers the springs. The pad system includes a wall pad extending upwardly from the springs and terminating at a pad system apex. The pad system further includes a buttress pad connected to the pad system apex at an apex angle from the wall pad, which is defined as an angle between a wall pad outside surface and the buttress pad. The buttress pad extends downwardly to cover at least partially the trampoline frame horizontal portion.
