Solution Overview

Problem

Existing connecting means for furniture or machine parts lack simplicity and reliability in connecting components, often requiring high forces for assembly and precision, which can lead to component damage and increased manufacturing complexity.

Innovation Solution

A connecting means featuring a first connecting element with a spring element and a second connecting element with a receiving element, where the spring element engages with the receiving element, and reinforcing elements enhance the spring force, allowing for a simple and secure connection by utilizing auxiliary spring elements and stiffening elements to increase the holding force.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional connecting means are used to connect furniture or machine parts, then the connection can be achieved, but the assembly process requires high forces and precision which increases the risk of component damage and manufacturing complexity

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a spring element that provides dynamic, elastic engagement between connecting elements. The spring element can deform elastically during assembly to accommodate tolerances and then maintains a constant holding force in the connected state, replacing rigid mechanical connections with a dynamic system that is both simpler to manufacture and more reliable.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the mechanical parameters of the connection system by introducing a spring element with specific elastic properties. The spring element's force-displacement characteristics allow the connection to accommodate variations in assembly parameters (tolerances) while maintaining reliable connection, eliminating the need for high-precision manufacturing.

Inventive Principle:
Principle #35Parameter changes

2Force

If conventional connecting means are used, then components can be connected, but high assembly forces are required which can damage components

Engineering Contradiction:
Improveholding forceVSAvoidcomponent damage during assembly
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

The spring element provides a dynamic connection mechanism where the elastic deformation absorbs assembly forces and gradually engages the connection. This dynamic engagement replaces high instantaneous forces with progressive elastic deformation, preventing component damage while achieving reliable connection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring element acts as a cushioning element that absorbs and distributes assembly forces before the final connection is established. The elastic properties of the spring element protect components from shock and impact forces during the assembly process.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of operation

If simple connecting means are used, then assembly is easier, but the holding force may be insufficient for reliable connection

Engineering Contradiction:
Improveassembly simplicityVSAvoidholding force
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The spring element creates a dynamic connection system that is simple to assemble (just insert and engage) but provides strong holding force through elastic recovery. The spring element's natural elasticity converts simple insertion motion into sustained connection force without requiring complex assembly procedures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring element is self-actuating - it automatically engages and maintains connection through its elastic properties without requiring external actuation or complex mechanisms. The spring element's inherent elasticity provides both the simplicity of operation and the strength of connection.

Inventive Principle:
Principle #25Self-service
