Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting node arrangements for two- or three-dimensional structures, such as furniture systems, face challenges in achieving simple assembly while maintaining high mechanical stability, often resulting in weak points due to eccentricities and requiring complex assembly processes.
Innovation Solution
A connecting node arrangement featuring flattened end sections with depressions and corresponding projections on fixing elements, allowing for both non-positive and positive connections, and utilizing spring elements to facilitate assembly and enhance stability, ensuring all end sections are in the same plane for improved structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If individual end sections are fixed via individual connecting elements, then mechanical stability is improved, but assembly complexity and cost increase
Solution Approach 1:
Multiple individual connecting elements are merged into a single common connecting element that simultaneously connects multiple end sections to the supporting structure. This reduces the number of connecting elements from multiple individual pieces to one unified piece, simplifying assembly while maintaining mechanical stability through the combined connection of all end sections.
2Ease of operation
If end sections are connected in different planes, then assembly is simplified, but structural stability deteriorates due to eccentricities
Solution Approach 1:
The connecting element is designed with a three-dimensional structure that includes connection portions extending in different directions and a connecting portion that connects to the supporting structure. This spatial arrangement allows end sections to be connected in different planes while maintaining structural stability by distributing connections across multiple dimensions and eliminating eccentricities through the coordinated geometry of the connecting element.
