Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional coupling pins with cotter pins are used to connect scaffolding frame elements, then the connection is secure, but the assembly process requires multiple components and complex manipulations reducing assembly speed

Engineering Contradiction:
Improveconnection securityVSAvoidassembly speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent combines multiple separate components (coupling pin, aligning holes, cotter pins) into a single integrated coupling element. The U-shaped profile with legs and tilting finger creates one piece that performs alignment, connection, and locking functions simultaneously, eliminating the need for multiple separate operations during assembly

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The tilting finger automatically secures itself through gravitational force after insertion. The finger tilts during insertion and then self-locks in place without requiring additional components like cotter pins or manual securing operations, making the assembly process self-completing and significantly faster

Inventive Principle:
Principle #25Self-service

2Reliability

If coupling pins with aligning holes and cotter pins are used, then the connection is reliable, but the number of components increases device complexity

Engineering Contradiction:
Improveconnection reliabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the coupling pin body, alignment features, and locking mechanism into a single U-shaped component. The legs of the U-profile serve as alignment features while the tilting finger provides automatic locking, eliminating the need for separate aligning holes and cotter pins

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single coupling element performs multiple functions simultaneously: the U-shaped legs provide alignment and positioning, the body connects the scaffolding elements, and the tilting finger provides automatic securing. This multi-functional design replaces what previously required three or more separate components

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

AI summary

A coupling pin clip for a coupling piece for the connection of two components that are inserted between them. To affix the insertable coupling at the ends of the coupling piece, a pin is insertable both through a hole of the component and through a hole of the coupling piece. The coupling pin clip is U-shaped, the legs of which have a distance from each other that corresponds to the distance of the two holes in the coupling piece. Furthermore, the coupling pin clip comprises a tipping finger articulated at one end of the coupling pin clip.
