Engineering Contradiction Analysis
1Measurement precision
If manual comparison methods are used to identify changes in wiring harness configurations, then no reproducible nomenclature is needed, but the process takes over twelve hours and is extremely labor-intensive
Solution Approach 1:
The patent changes the parameter of node identification from model-specific sequential numbers to a standardized reproducible nomenclature system. This allows automated electronic comparison of wiring harness configurations, reducing the comparison process from over twelve hours of manual work to a fraction of that time while maintaining precise change identification.
Solution Approach 2:
The patent replaces the mechanical manual comparison process with an automated electronic system. By implementing a standardized nomenclature that can be processed electronically, the system substitutes human manual review with computer-based automated comparison, dramatically reducing time consumption while improving consistency.
2Adaptability or versatility
If model-specific sequential IDs are used in current wiring harness design software, then each vehicle's wiring harness can be uniquely identified, but the same components have different IDs on different drawings making electronic analysis and comparison very complex and laborious
Solution Approach 1:
The patent creates a universal nomenclature system that serves multiple functions: it uniquely identifies components within a specific vehicle model while also enabling consistent identification across different vehicle models and drawings. This standardized system allows the same component to have the same ID across all drawings, enabling automated electronic analysis and comparison while maintaining vehicle-specific configuration flexibility.
Solution Approach 2:
Instead of using model-specific prefixes that create complexity, the patent inverts the approach by using a standardized base nomenclature that remains consistent across all models. The vehicle-specific identification is achieved through the combination of standardized component names with vehicle-specific configuration data, rather than through model-specific ID prefixes.
3Manufacturing precision
If the entire modeling board is discarded when modifications are needed, then starting fresh ensures accuracy, but this is wasteful and inefficient
Solution Approach 1:
The patent implements preliminary action by establishing a standardized reproducible nomenclature system before modifications are made. This allows the existing modeling board data to be automatically processed and updated electronically, enabling accurate modifications without discarding the original board. The standardized naming convention allows software to automatically track and implement changes while maintaining data integrity.
Solution Approach 2:
The patent uses copying by creating updated versions of the wiring harness configuration data rather than discarding the original. The standardized nomenclature enables electronic copying and modification of the modeling board data, allowing manufacturers to preserve the original board while generating updated configurations through systematic data replication and modification.

AI summary
A unique reproducible nomenclature for all components of a wiring harness is provided such that automatic calculation and re-calculation of wiring harness configurations is made possible. Specifically, automated updating of identification tags for harness nodes, bundles, parts from/referring to these topology elements without connectors/connections/cable lugs, as well as accessories referring to connectors, is provided for using a unique reproducible nomenclature and set of predefined rules.
