Prototype Wiring Synthesis in Vehicle Harness Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wiring synthesis tools for designing electrical systems, such as wiring harnesses, often require extensive manual editing and re-synthesis whenever the logical design is modified, as existing constraints are insufficient to control the physical design effectively, leading to time-consuming processes.
Innovation Solution
A computing system that receives a specification of prototype wiring for a logical design, locates the corresponding section in a vehicle, and inserts the prototype wiring into a physical design, while using constraints to generate the remaining physical design, thereby reducing the need for manual editing and re-synthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual editing tools are used to alter synthesized physical design, then design flexibility is improved, but time consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-defining wiring constraints and prototype wiring configurations before the synthesis process. Designers can specify constraints on wire routing, connector placement, and harness topology in advance, allowing the synthesis tool to automatically generate designs that meet these requirements without requiring subsequent manual editing. This proactive constraint specification reduces the need for time-consuming post-synthesis adjustments.
Solution Approach 2:
The synthesis tool is enhanced to automatically detect and preserve prototype wiring configurations during the synthesis process without requiring manual intervention. The system self-adjusts to maintain predefined wiring patterns while generating the complete physical design, eliminating the need for designers to manually edit and re-synthesize repeatedly. This self-preserving capability reduces both time consumption and manual effort.
2Adaptability or versatility
If logical design is modified and re-synthesized, then design updates are achieved, but manual editing must be re-performed
Solution Approach 1:
The patent implements feedback mechanisms where the synthesis tool automatically detects changes in the logical design and adjusts the physical design accordingly while preserving existing wiring constraints and prototype configurations. When logical design modifications are made, the system provides feedback to maintain consistency with predefined constraints without requiring complete re-synthesis or manual re-editing. This feedback loop maintains design integrity while improving productivity.
Solution Approach 2:
By pre-establishing wiring constraints and prototype configurations that are independent of specific logical design variations, the system enables rapid adaptation to design changes. These preliminary constraints act as a stable framework that remains valid across multiple logical design iterations, eliminating the need to re-perform manual editing for each update.
3Manufacturing precision
If constraints are provided to control wiring synthesis, then physical design control is improved, but constraint sufficiency is insufficient
Solution Approach 1:
The patent segments constraints into multiple hierarchical levels: global constraints (affecting entire harness), regional constraints (affecting specific vehicle sections), and local constraints (affecting individual wiring paths). This segmentation allows designers to apply appropriate levels of control without overwhelming the system with insufficient or overly broad constraints. Each constraint level can be independently configured and preserved during synthesis.
Solution Approach 2:
The constraint system is designed to be universal and multi-functional, where a single constraint framework can handle various types of wiring requirements (routing, connector placement, harness topology, prototype preservation) through a unified interface. This universal constraint mechanism improves both physical design control and adaptability by providing a versatile tool that can accommodate diverse design requirements without needing separate constraint sets.

AI summary
This application discloses a computing system to receive a specification of prototype wiring corresponding to a signal in a logical design of a wire harness, locate a section of a vehicle to include a portion of the wire harness corresponding to the signal in the logical design, and insert the prototype wiring into a physical design of the wire harness corresponding to the located section of the vehicle. The specification of the prototype wiring can identify a particular vehicle configuration and insert the prototype wiring into a physical design of the wire harness for the particular vehicle configuration. The computing system can receive constraints configured to control synthesis of the logical design into the physical design of the wire harness, and generate portions of the physical design of the wire harness based on the constraints, while retaining the prototype wiring that was inserted into the physical design.
