Solution Overview

Problem

Existing composite components for air conditioning devices in buildings are complex and costly to produce, requiring additional stiffening frames for stability, which increases weight and complexity.

Innovation Solution

A composite component design featuring a self-supporting structure with a heat-conducting plate and a carrier plate of U-shaped cross-section, where the carrier plate's legs encompass the heat-conducting plate, eliminating the need for external frames by providing inherent rigidity and allowing direct attachment to building surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If additional stiffening frames are used to ensure stability, then structural rigidity is improved, but device complexity and weight increase

Engineering Contradiction:
Improvestructural rigidityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The carrier plate is integrated directly into the composite component, merging the support function with the main structure. The U-shaped cross-section of the carrier plate provides inherent rigidity without requiring separate stiffening frames, thus reducing device complexity while maintaining structural stability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The carrier plate employs a U-shaped cross-section geometry that utilizes three-dimensional structural efficiency. This dimensional design provides high rigidity-to-weight ratio, eliminating the need for additional frames while maintaining structural integrity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If additional stiffening frames are used to ensure stability, then structural rigidity is improved, but weight increases

Engineering Contradiction:
Improvestructural rigidityVSAvoidweight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The carrier plate is integrated directly into the composite component, merging the support function with the main structure. This eliminates the need for separate stiffening frames, thereby reducing overall weight while maintaining structural rigidity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The thin-walled U-shaped carrier plate structure provides high strength-to-weight ratio. The optimized wall thickness and geometric shape deliver sufficient rigidity without requiring heavy materials or additional framing, thus minimizing weight

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of manufacture

If the composite component is designed to be inherently rigid and self-supporting, then ease of manufacture is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveease of manufactureVSAvoidmanufacturing precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The composite component is divided into distinct functional elements (heat-conducting plate, carrier plate, insulation layer) that can be manufactured separately and then assembled. This segmentation allows each component to be optimized for its specific manufacturing process while maintaining overall precision requirements

Inventive Principle:
Principle #1Segmentation
