Solution Overview

Problem

Existing systems for thermally insulating panels with steel elements face issues such as rust formation and inefficient assembly due to capillary action of rainwater and the costly, time-consuming process of providing clamping recesses in steel elements.

Innovation Solution

The system employs connecting elements with steel flanges fixed to steel surfaces via energy beam welding, allowing for a durable, water-tight coupling of thermally insulating parts to steel elements without the need for clamping recesses, using fiber-reinforced materials and stainless steel profiles for enhanced durability and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If clamping recesses are provided in steel elements to connect insulating parts, then the connection is achieved, but the manufacturing process becomes costly and time-consuming

Engineering Contradiction:
Improveconnection reliabilityVSAvoidassembly efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The connection system is divided into separate functional components: steel elements provide structural support, insulating parts provide thermal insulation, and connecting elements (screws/bolts) provide the mechanical connection. This segmentation allows each component to be optimized independently and assembled efficiently without requiring complex integrated features like clamping recesses.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Connecting elements act as intermediaries between the steel elements and insulating parts, enabling a simple, efficient connection without requiring complex integrated features in either component. The connecting elements mediate the connection function, allowing for rapid assembly while maintaining reliable mechanical attachment.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If steel elements are used for structural support, then strength is achieved, but rust formation occurs due to capillary action of rainwater

Engineering Contradiction:
Improvestructural strengthVSAvoidrust formation
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The insulating parts serve as intermediary components between steel elements that are exposed to rainwater. These insulating parts break the continuous steel pathways that would otherwise allow capillary action to transport water to connection points, thereby preventing rust formation while maintaining structural integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Different materials are used in different locations based on their specific functional requirements: steel elements provide structural strength where needed, while insulating parts provide corrosion protection and thermal insulation in locations where they can interrupt water pathways and reduce heat transfer.

Inventive Principle:
Principle #3Local quality

3Reliability

If multiple components are used to achieve water-tight coupling, then water-tightness is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvewater-tightnessVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The insulating parts function as intermediary components that simultaneously provide multiple functions: thermal insulation, corrosion protection by interrupting water pathways, and mechanical connection support. This multi-functionality reduces the need for additional dedicated components for each function.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The insulating parts are designed to perform multiple functions within a single component: providing thermal insulation, preventing corrosion by breaking capillary water pathways, and serving as a mounting surface for connecting elements. This universal approach reduces overall system complexity despite achieving multiple protective functions.

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