Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If step parts are selected and installed according to empirical values, then the assembly process is facilitated, but high outlay and risk of damaging components occur due to repeated assembly and disassembly
Solution Approach 1:
The patent applies preliminary action by measuring all individual components before assembly and calculating the required step part dimensions in advance. This pre-calculation eliminates the need for iterative assembly and disassembly, as the correct step parts are selected before the assembly process begins, thereby reducing time loss while maintaining ease of operation.
2Manufacturing precision
If iterative assembly and disassembly is performed to achieve desired spacings, then dimension accuracy is improved, but component damage risk increases
Solution Approach 1:
The patent performs all necessary measurements and calculations before assembly begins. By determining the exact dimensions of individual components and calculating the required step part dimensions in advance, the correct parts are selected prior to assembly. This eliminates iterative assembly and disassembly cycles, thereby maintaining manufacturing precision while preventing component damage.
Solution Approach 2:
The patent creates a digital model or representation of the assembly module based on measured component dimensions. This virtual model allows for calculation and verification of step part dimensions without physical assembly, eliminating the need for repeated trial-and-error assembly that could damage components while ensuring precise spacing requirements are met.
3Manufacturing precision
If frequent changes of step part dimensions occur during iterative process, then desired spacings are achieved, but documentation clarity and traceability deteriorate
Solution Approach 1:
The patent determines all step part dimensions through calculation based on pre-measured component data before assembly begins. Since the correct step parts are identified in advance through the calculation model, there are no frequent changes during the assembly process. This ensures both precise spacings are achieved and clear, unambiguous documentation is maintained, as each step part selection is deliberate and documented from the outset.
4Productivity
If measurement and calculation of all individual components is performed before assembly, then iterative assembly is eliminated, but measurement and calculation complexity increases
Solution Approach 1:
The patent creates a digital model or virtual representation of the assembly module based on measured component dimensions. This digital copy allows for automated calculation of step part requirements without complex manual computations. The measurement data is systematically processed through a calculation model that automatically determines the correct step part dimensions, simplifying the overall process while eliminating iterative assembly and improving productivity.

AI summary
The disclosure relates to a method for preselecting at least one step part of an assembly module, comprising the steps of: measuring individual components which, in the mounted state together with at least one step part, create the assembly module, calculating a model of the assembly module using the dimensions obtained during the measurement of the individual components, and determining the dimensioning of the at least one step part on the basis of the calculated model and the allowable tolerances of the assembly module.
