Solution Overview

Problem

Existing support devices for external air-conditioning units are complex, requiring multiple components and separate coupling elements, leading to increased production, storage, and assembly costs, as well as vulnerability to corrosion due to metal construction.

Innovation Solution

A support device with self-carrying legs and integral bracket-like portions that include connection means for removably connecting pairs of legs, eliminating the need for additional coupling elements and allowing for modular configuration to support both air-conditioning units and condensate collection tanks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If portal-like frames are used to support the condensate collection tank, then the tank can be supported in a raised position, but the structure requires multiple separate components and coupling elements that increase complexity and assembly costs

Engineering Contradiction:
Improvesupport stabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The support leg integrates multiple functions into a single component: it provides ground support, incorporates an integral bracket-like portion for tank support, and includes connection means for assembling the portal structure. This merging eliminates the need for separate coupling elements and reduces the total number of components while maintaining structural stability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support leg is designed as a multi-functional element that simultaneously performs grounding, tank support (via the integral bracket), and structural connection (via the connection means). This universal design allows a single component to replace multiple specialized parts, reducing complexity and assembly requirements.

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

2Strength

If metal portal-like frames are used for support, then the structure provides necessary strength and stability, but the metal construction is susceptible to corrosion

Engineering Contradiction:
Improvestructural strengthVSAvoidcorrosion resistance
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The support leg is constructed from plastic material that incorporates fiberglass reinforcement, creating a composite structure that provides metal-level strength and stability while being inherently resistant to corrosion. The fiberglass-reinforced plastic combines the tensile strength of fiberglass with the corrosion resistance and formability of plastic.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If separate coupling elements are used to connect the portal frames, then the assembly allows for modular construction, but the number of components increases production, storage, and assembly costs

Engineering Contradiction:
Improvemodular configurationVSAvoidproduction and assembly costs
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The connection means are integrated directly into the support leg structure rather than being separate components. This merging maintains the modular assembly capability (the portal structure can still be assembled from multiple legs) while eliminating the need for additional coupling elements, thereby reducing production, storage, and assembly costs.

Inventive Principle:
Principle #5Merging (Combining)

4Stability of the object's composition

If the bracket-like portion is made integral with the leg, then the support structure is simplified and more stable, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvestructural stabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The fiberglass-reinforced plastic material allows for the integration of complex three-dimensional shapes (including the bracket-like portion) to be molded as a single piece. The reinforcement provides the necessary structural strength for the integral design while the plastic matrix allows for complex geometries to be formed through molding processes, making the integrated structure manufacturable.

Inventive Principle:
Principle #40Composite materials
