Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If an inflatable pool wall is used, then the pool can be easily assembled and disassembled, but the thermal insulation performance deteriorates and the structure becomes prone to deformation and damage

Engineering Contradiction:

Improveassembly easeVSAvoidstructural stability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The pool wall structure transitions from an inflatable state-dependent form to a rigid non-inflatable form, fundamentally changing the structural parameter from flexible to fixed, thereby eliminating deformation issues while maintaining assembly ease through modular design

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The pool wall employs a composite structure combining inner wall, outer wall, top sheet, and support wall body (expanded polyethylene foam), creating a multi-layer composite system that provides both structural stability and thermal insulation without requiring inflation

Inventive Principle:

Principle #40Composite materials

2Loss of time

If an inflatable pool wall is used, then the pool can be quickly set up, but the thermal insulation performance deteriorates due to quick heat dissipation

Engineering Contradiction:

Improvesetup timeVSAvoidthermal insulation

Core Design Contradiction:

Loss of timeVSLoss of energy

Solution Approach 1:

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The support wall body is specifically positioned within the filling chamber to provide localized thermal insulation and structural support, addressing the heat dissipation issue at the critical wall region without affecting overall assembly speed

Inventive Principle:

Principle #3Local quality

3Reliability

If a non-inflatable design with support wall body is used, then thermal insulation and structural stability are improved, but the device complexity increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The pool wall is divided into distinct modular segments (inner wall, outer wall, top sheet, support wall body) that can be independently manufactured and assembled, reducing overall system complexity while maintaining structural integrity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support wall body is nested within the filling chamber formed by the inner wall, outer wall, and top sheet, creating a compact integrated structure that provides support and insulation without adding external complexity

Inventive Principle:

Principle #7Nested doll (Nesting)

4Volume of moving object

If an inflatable pool is used, then the pool occupies less storage space when deflated, but it requires time-consuming and laborious inflation and deflation processes

Engineering Contradiction:

Solution Approach 1:

The pool wall structure transitions from an inflatable state-dependent form to a rigid non-inflatable form, fundamentally changing the structural parameter from flexible to fixed, thereby eliminating assembly time while providing stable storage volume

AI summary

A non-inflatable above-ground pool is provided including a pool bottom and a pool wall connected to an edge of the pool bottom to thereby enclose a water storage cavity. The pool bottom includes interconnected upper bottom sheet and lower bottom sheets. The pool wall includes an inner and outer wall and a top sheet. Each of the inner wall and outer walls have an upper edge connected to the top sheet and a lower edge connected to the pool bottom, defining a filling chamber. Alternatively, inner and outer walls and top sheets are connected to an upper edge of each of the inner wall and the outer wall, thereby enclosing a filling chamber. A lower edge of the inner wall may be connected to the lower bottom sheet. A support wall body is disposed within the filling chamber, and in an embodiment, includes a wall body opening therethrough.
