Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular systems for frameless housing construction, such as heat and soundproof sandwich panels, face difficulties in assembly and disassembly due to complex insulation pieces and cover profiles, leading to tedious and challenging connections.
Innovation Solution
The use of connectors that can be completely sunk into depressions on the components, with angled contact and pressure surfaces allowing for easy assembly and disassembly, ensuring a secure and sealing connection without protruding beyond the components, and optionally using screws for additional fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If connectors are used to connect components in modular housing systems, then the connection strength and stability are improved, but the assembly and disassembly processes become tedious and complex
Solution Approach 1:
The connector is divided into multiple independent parts: a first connector part with a first pressing surface, a second connector part with a second pressing surface, and an insulation piece. These segmented components can be independently assembled and disassembled, simplifying the overall assembly process while maintaining strong connections through the coordinated action of multiple parts.
Solution Approach 2:
The insulation piece acts as an intermediary element between the first and second connector parts. It facilitates the connection by providing a mating interface with corresponding pressing surfaces, enabling easy assembly through simple insertion while ensuring stable and insulated connection between components.
2Object-affected harmful factors
If complex insulation pieces and cover profiles are used in modular systems, then the thermal and acoustic insulation performance is improved, but the assembly process becomes more difficult and time-consuming
Solution Approach 1:
The insulation function is merged into the connector structure itself through the insulation piece integrated between the first and second connector parts. This eliminates the need for separate insulation components and cover profiles, reducing assembly steps while maintaining effective thermal and acoustic insulation between connected components.
3Device complexity
If connectors protrude beyond component surfaces, then the connection structure is simplified, but the exterior surface finish becomes uneven and visible
Solution Approach 1:
The connector components are designed to nest within recesses or depressions on the component surfaces. The first connector part and second connector part fit into corresponding recesses, allowing the connector structure to be concealed within the component boundaries while maintaining structural integrity and connection strength.
4Adaptability or versatility
If multiple separate components are used for connection, then the adaptability and versatility of the modular system is improved, but the device complexity increases
Solution Approach 1:
The connector assembly serves multiple functions simultaneously: the first connector part and second connector part provide mechanical connection, the insulation piece provides thermal and acoustic insulation, and the integrated design allows for easy assembly and disassembly. This multi-functionality reduces the need for separate specialized components, maintaining versatility while managing complexity.

AI summary
The system has a connector (3) for connecting a plate (1) e.g. sandwich plate, and a sectional strip in a connected position. The connector is attached on contact surfaces (5) of the respective plate and strip in a linearly running attachment direction (7) by pressure surfaces of the connector. The contact surfaces and/or pressure surfaces are sectionally arranged transverse to the attachment direction. The pressure surfaces lie at the contact surfaces and press front surfaces of the respective plate and strip against each other. The plate is limited at its front surface by an edge profile.
