Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If interval adjustment is used for the platform, then the structure is simple, but the adaptability to different elevator shaft dimensions is insufficient
Solution Approach 1:
The patent implements dynamic adjustment capability through long holes arranged at multiple inclined angles in the beam assemblies. These long holes allow the platform to be adjusted continuously between different positions, transforming a static structure into a dynamic one that can adapt to various elevator shaft dimensions without requiring complex mechanisms.
Solution Approach 2:
The patent changes the geometric parameters of the platform by utilizing long holes at different inclined angles. By selecting different hole positions and angles, the platform can be configured for different rail gauges and shaft dimensions, achieving adaptability through parameter variation rather than structural complexity.
2Strength
If the platform uses conventional fixed structure, then the manufacturing is simple, but the load capacity is insufficient for medium and high rise buildings
Solution Approach 1:
The patent divides the platform into multiple beam assemblies (upper beam assembly and lower beam assembly) with separate long holes. This segmentation allows each component to be manufactured independently with standard processes, while the assembled structure achieves enhanced load capacity through the distributed long hole configuration that provides multiple adjustment positions and angles.
3Productivity
If scaffoldings are used for installation, then the equipment is simple, but the installation time is long and labor intensity is high
Solution Approach 1:
The patent creates a universal installation platform that can be adjusted to fit different elevator shaft dimensions and rail gauges through its long hole configuration. This single platform design serves multiple functions and applications, replacing the need for multiple specialized platforms or traditional scaffoldings, thereby improving installation efficiency without requiring overly complex equipment.
4Adaptability or versatility
If the platform is not adjustable, then the structure is simple, but it cannot adapt to various dimensions and rail gauges
Solution Approach 1:
The patent introduces dynamic adjustability through long holes arranged at multiple inclined angles in the beam assemblies. This allows the platform to be repositioned continuously between different angles and positions, providing adaptability to various dimensions and rail gauges without requiring complex adjustment mechanisms.
