Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If holding devices with hook or mushroom-shaped projections are used to connect step elements to stringers, then the assembly and disassembly can be simplified, but the manufacturing cost increases and the structure becomes more complex
Solution Approach 1:
The invention extracts the complex holding device from the system and replaces it with a simple console structure integrated into the stringer. The step element itself is designed with features that enable direct placement on the console, eliminating the need for separate holding devices while maintaining ease of assembly and disassembly
Solution Approach 2:
The console is merged with the stringer structure, and the step element is designed to work directly with the console. This integration eliminates the need for separate holding devices, reducing overall system complexity while preserving the simple assembly process
2Reliability
If holding devices are used to secure step elements to stringers, then the connection is reliable, but the manufacturing cost increases
Solution Approach 1:
The expensive holding device is extracted from the system and replaced with a simple console structure. The step element is designed with inherent features that provide reliable connection to the console without requiring additional expensive components
Solution Approach 2:
The invention uses simple, inexpensive console structures and step elements that can be easily manufactured. These components are designed to be replaced or reconfigured as needed, providing cost-effective solutions while maintaining reliable connections
3Ease of manufacture
If fixed-dimensional stringers and step elements are used, then manufacturing is simplified, but the stairway lacks scalability and configuration flexibility
Solution Approach 1:
The stairway is divided into modular components (stringers, step elements, consoles) that can be manufactured in standard dimensions but combined in various configurations. This segmentation allows for scalable designs while maintaining manufacturing simplicity through standardization
Solution Approach 2:
The console and step element design provides universal functionality that works across different stair configurations. The same basic components can be used to create various stairways by changing the arrangement and number of elements, providing both manufacturing simplicity and configuration flexibility
