Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a socketing structure is used for connection, then the installation is simple, but cracks or unevenness occur at connection positions causing instability and derailment risk
Solution Approach 1:
The connection structure is divided into multiple functional components: a docking plate with upright plugging plates for insertion, buckling blocks for mechanical interlocking, and fixing side plates with fixing holes for secure attachment. This segmentation allows each component to perform its specific function optimally while maintaining overall connection reliability.
Solution Approach 2:
The upright plugging plates are pre-installed on the docking plate, and the buckling blocks are positioned in advance on the guide rail. This preliminary preparation ensures that when the connection is made, the components align properly without requiring complex adjustment during installation, maintaining both simplicity and reliability.
2Productivity
If a socketing structure is used for connection, then the installation process is quick, but unevenness occurs causing the elevator to stall during operation
Solution Approach 1:
The buckling blocks are pre-positioned on the guide rail at precise locations, and the upright plugging plates are pre-installed on the docking plate. This advance preparation ensures that during quick installation, the components align automatically, achieving both fast installation and smooth operation without stalling.
Solution Approach 2:
The buckling blocks serve as intermediary elements that mediate between the docking plate and the guide rail. They provide a precise mechanical interface that ensures proper alignment and smooth contact, preventing unevenness and stalling while maintaining quick installation.
3Device complexity
If only socketing is used for fixing, then the structure is simple, but the fixing is unstable creating derailment danger at high speeds
Solution Approach 1:
The fixing system is segmented into multiple independent but coordinated components: the docking plate for positioning, upright plugging plates for insertion, buckling blocks for mechanical interlocking, and fixing side plates with fixing holes for secure attachment. This segmentation provides both structural simplicity and fixing stability.
Solution Approach 2:
Multiple fixing mechanisms are merged into a single integrated connection system. The docking plate combines insertion (upright plugging plates), interlocking (buckling blocks), and bolting (fixing side plates with fixing holes) functions, achieving stable fixing at high speeds while maintaining overall structural simplicity.
