Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the driver relies on conventional driving methods without real-time weight and electrical load information, then the driving operation is simple, but the driving distance is reduced and fuel efficiency deteriorates
Solution Approach 1:
The system segments the eco-driving information provision into distinct functional modules: a vehicle weight calculating unit that determines current vehicle weight, an electrical load computing unit that calculates total electrical load from multiple auxiliary devices, and a vehicle speed calculating unit that determines optimal speed. This segmentation allows complex eco-driving computation to be broken down into manageable, independent calculation processes that can be implemented systematically.
Solution Approach 2:
The patent introduces an intermediary information processing system that acts as a mediator between the vehicle's various parameters (weight, electrical load) and the driver. This intermediary calculates and provides optimal vehicle speed information based on current vehicle conditions, enabling the driver to make informed decisions without directly computing complex relationships between multiple variables.
2Use of energy by moving object
If the driver adjusts speed based on real-time weight and electrical load information, then fuel efficiency is improved, but the difficulty of detecting and measuring vehicle parameters increases
Solution Approach 1:
The vehicle speed calculating unit serves multiple functions: it receives vehicle weight data, processes electrical load information from multiple auxiliary devices, and outputs optimal speed recommendations. This multi-functional approach consolidates what would otherwise require separate detection and measurement systems into a single integrated unit that handles all parameter processing.
Solution Approach 2:
The system utilizes existing vehicle data infrastructure to obtain weight and electrical load information without requiring external measurement devices. The vehicle's own sensors and control units provide the necessary data, and the speed calculating unit processes this self-generated information to determine optimal driving parameters.
3Duration of action of moving object
If the driver is provided with detailed eco-driving information, then driving distance is extended, but the ease of operation decreases due to information processing requirements
Solution Approach 1:
The system extracts only the essential information needed for eco-driving - the optimal vehicle speed - from the complex set of vehicle parameters. By presenting just this single key parameter to the driver rather than raw weight and electrical load data, the system maintains ease of operation while still enabling extended driving distance through informed speed selection.
Solution Approach 2:
The system transforms multiple vehicle parameters (weight, electrical load from multiple devices) into a single actionable parameter (optimal vehicle speed). This parameter transformation simplifies the driver's task while capturing the cumulative effect of all vehicle conditions on fuel efficiency and driving distance.
