Solution Overview

Problem

Existing construction panel assemblies face challenges in ensuring thermal insulation continuity and mechanical strength at junctions, leading to thermal bridges and inadequate airtightness, particularly when connecting panels or attaching them to building elements like slabs or beams.

Innovation Solution

The assembly features panels with spacers and connecting elements that allow for easy positioning and high mechanical strength, ensuring structural loads are absorbed and thermal insulation is continuous, using flat contacts on large surfaces to minimize stress concentrations and eliminate thermal bridges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If panels are connected using conventional joining methods, then mechanical strength is improved, but thermal insulation continuity deteriorates due to thermal bridges at junctions

Engineering Contradiction:
Improvemechanical strengthVSAvoidthermal insulation continuity
Core Design Contradiction:
StrengthVSLoss of energy

Solution Approach 1:

The patent introduces a connecting element that acts as an intermediary component between panels. This connecting element includes an insulation portion that extends between the inner webs of adjacent panels, serving as a thermal bridge breaker while the connection portion provides mechanical joining. The intermediary structure allows both mechanical strength and thermal insulation continuity to be achieved simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If panels are joined with tight fitting to ensure airtightness, then airtightness is improved, but assembly complexity increases due to precision requirements

Engineering Contradiction:
ImproveairtightnessVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connecting element is segmented into distinct functional portions: a connection portion for mechanical joining and an insulation portion for thermal and airtight sealing. This segmentation allows each portion to be optimized independently - the connection portion provides structural integrity while the insulation portion with its extended shape automatically fills gaps and ensures airtightness without requiring high precision assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insulation portion of the connecting element is designed to automatically fill the space between inner webs of adjacent panels through its extended shape. This self-service mechanism ensures airtightness and thermal insulation continuity without requiring additional sealing operations or high precision positioning, thereby reducing assembly complexity.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If spacer protrudes from panel to enable connection, then ease of assembly is improved, but structural integrity deteriorates due to potential buckling under load

Engineering Contradiction:
Improveease of assemblyVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The connecting element is constructed as a composite structure combining a connection portion (for mechanical joining) and an insulation portion (for thermal insulation and structural support). The insulation portion extends between inner webs to provide load-bearing capacity and prevent buckling, while the connection portion facilitates easy assembly. This composite design allows the spacer to protrude for ease of assembly without compromising structural integrity.

Inventive Principle:
Principle #40Composite materials
