Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles are dispatched without real-time monitoring and route optimization, then operational flexibility is maintained, but resource efficiency deteriorates due to unnecessary vehicle movement and rolling all day long
Solution Approach 1:
The central computing station pre-calculates optimized supply routes based on multiple parameters including vehicle location, stationary tank locations, traffic conditions, and weather conditions before dispatch. This preliminary route planning eliminates unnecessary vehicle movement and optimizes resource efficiency before the vehicle even starts its journey.
Solution Approach 2:
The system continuously monitors vehicle location, delivery status, and operational parameters in real-time through GPS tracking and communication devices. This feedback loop allows the central computing station to dynamically adjust routes and dispatch decisions, improving resource efficiency while maintaining operational flexibility.
2Measurement precision
If manual monitoring and authorization methods are used, then system simplicity is maintained, but measurement precision deteriorates regarding LPG volume supplied to stationary tanks
Solution Approach 1:
Manual monitoring and authorization methods are replaced with an automated electronic system that uses communication devices, central computing stations, and digital authorization protocols. This substitution eliminates human error in measurement recording and provides precise, real-time tracking of LPG volume supplied to stationary tanks.
Solution Approach 2:
A central computing station acts as an intermediary between the dispensing vehicle and the stationary tank, coordinating the dispensing operation and verifying measurements. This intermediary system ensures accurate measurement by cross-checking data from multiple sources and providing centralized authorization and monitoring.
3Reliability
If real-time monitoring and authorization systems are implemented, then delivery security is improved, but device complexity increases
Solution Approach 1:
The control system is segmented into distinct functional modules: authorization module, monitoring module, communication module, and control module. Each module performs a specific function and can be independently managed, which reduces overall system complexity while maintaining comprehensive security through coordinated operation of all segments.
4Productivity
If centralized route optimization is implemented, then productivity is improved, but loss of information increases due to communication requirements
Solution Approach 1:
The communication device in the vehicle serves multiple functions: GPS location tracking, receiving route instructions from the central computing station, transmitting delivery status updates, and receiving authorization codes. This multi-functional approach consolidates multiple data transmission requirements into a single universal communication system, improving route efficiency while minimizing information loss.
