Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security systems are installed by modifying the vehicle wiring harness, then security functionality is achieved, but installation time increases and skilled personnel are required
Solution Approach 1:
The security system is divided into separate functional modules: a control unit that interfaces with the telematics device and a relay module that interfaces with the wiring harness. This segmentation allows the relay module to be installed as a standalone component without requiring modification of the existing wiring harness, thereby reducing installation time and eliminating the need for skilled personnel while maintaining security functionality.
Solution Approach 2:
The relay module acts as an intermediary component between the vehicle's existing wiring harness and the security control system. It provides standardized plug-in connections that interface with the telematics device through the existing electrical system without requiring wire cutting or splicing, thus achieving security functionality while avoiding time-consuming installation procedures.
2Reliability
If traditional security systems are installed by modifying the vehicle wiring harness, then security functionality is achieved, but the wiring harness integrity is compromised
Solution Approach 1:
By segmenting the security system into a separate relay module that plugs into the existing wiring harness rather than integrating it into the harness itself, the original wiring structure remains intact. This modular approach allows security functionality to be added without cutting, splicing, or permanently modifying the vehicle's wiring harness, thereby preserving its environmental integrity and long-term reliability.
Solution Approach 2:
The relay module serves as an intermediary that connects to the wiring harness through standardized plug-in interfaces without requiring modification of the harness. This mediator approach enables the security system to interface with the vehicle's electrical system while leaving the original wiring harness composition unchanged, thus maintaining its stability and preventing potential electrical problems.
3Reliability
If security systems require wiring harness modification, then installation is secure, but removal becomes difficult and may compromise wiring integrity
Solution Approach 1:
The relay module is designed as a separate, self-contained unit that connects to the wiring harness through reversible plug-in connectors rather than permanent modifications. This segmentation enables the security system to be easily removed by simply unplugging the relay module, restoring the wiring harness to its original state without requiring repair or modification, thus greatly improving ease of removal and system disposal.
Solution Approach 2:
The relay module acts as a removable intermediary component that can be easily inserted and removed from the wiring harness without causing damage. Its standardized plug-in design ensures secure installation while allowing equally easy removal, eliminating the difficulties associated with removing traditionally installed security systems that require wire cutting or splicing.
4Manufacturing precision
If skilled personnel are used for installation, then installation quality is ensured, but installation cost increases
Solution Approach 1:
By segmenting the security system into a modular relay module with standardized plug-in connections, the installation process is simplified to a basic connect-disconnect operation that does not require skilled personnel. This modular design maintains installation quality through standardized interfaces while dramatically reducing labor costs by enabling installation by unskilled workers.
Solution Approach 2:
The relay module as an intermediary component provides standardized, self-explanatory plug-in connections that eliminate the need for complex wiring procedures. This design ensures installation quality through standardized interfaces while reducing installation cost by removing the requirement for expensive skilled labor, allowing any personnel to perform the installation.
