Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional connecting devices are used for assembling facade elements, then assembly can be performed with simple structures, but assembly speed and precision are insufficient

Engineering Contradiction:
Improveassembly speedVSAvoidconnecting device structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The connecting device is divided into multiple independent components: first connecting elements with positive locking elements at lower corners, second connecting elements with counter-elements at upper corners, and separate brackets for supporting structure attachment. This segmentation allows each component to perform its specific function efficiently while enabling rapid assembly through modular installation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting elements act as intermediary components between facade elements and the supporting structure. The positive locking elements and counter-elements serve as mediators that enable precise alignment and secure connection, facilitating quick assembly without requiring complex adjustment mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If simple connecting devices are used, then device structure remains simple, but horizontal alignment precision deteriorates

Engineering Contradiction:
Improvehorizontal alignment precisionVSAvoidconnecting device structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The connecting device incorporates localized precision features at critical positions: positive locking elements and counter-elements are specifically designed with complementary geometries that engage to provide precise horizontal alignment. The brackets are positioned and shaped to attach to specific locations on the supporting structure, ensuring accurate positioning without requiring the entire device to be complex.

Inventive Principle:
Principle #3Local quality
