Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If small autonomous driving mobility is used for last mile delivery on irregular roads, then delivery capability in non-road sections is improved, but autonomous driving performance and understanding of complex environments deteriorates
Solution Approach 1:
The delivery system is segmented into two distinct components: a lead vehicle for autonomous driving on regular roads and a small autonomous driving mobility for last-mile delivery on irregular roads. This segmentation allows each component to be optimized for its specific function, with the lead vehicle handling complex environment understanding and the small mobility handling agile delivery in non-road sections.
Solution Approach 2:
The lead vehicle acts as an intermediary that provides remote control signals to the small autonomous driving mobility. Through this intermediary relationship, the small mobility can operate in complex environments by receiving guidance from the lead vehicle's autonomous driving system, effectively transferring the environmental understanding capability to the delivery platform.
2Reliability
If autonomous driving system is configured to understand complex environments, then delivery performance on irregular roads is improved, but cost deteriorates
Solution Approach 1:
The system merges the autonomous driving system from the lead vehicle with the small mobility platform. Instead of equipping the small mobility with a complete autonomous driving system, it leverages the lead vehicle's system through remote control and signal transmission, combining resources to achieve high performance at lower cost.
Solution Approach 2:
The lead vehicle's autonomous driving system serves multiple functions: it controls the lead vehicle itself and simultaneously provides remote control signals to the small mobility platform. This multi-functionality allows the same system to enhance both vehicles' performance without duplicating expensive components.
3Productivity
If lead vehicle and droid vehicle are coupled on regular road, then autonomous driving efficiency is improved, but adaptability to irregular roads deteriorates
Solution Approach 1:
The coupling between the lead vehicle and droid vehicle is made dynamic rather than fixed. The system can automatically release the coupling when approaching irregular roads, allowing the droid vehicle to operate independently in non-road sections while maintaining the efficiency benefits of coupling on regular roads.
4Adaptability or versatility
If droid vehicle operates independently on irregular road, then last mile delivery capability is improved, but remote control capability deteriorates
Solution Approach 1:
The remote control system incorporates feedback mechanisms where the droid vehicle transmits sensor data and status information back to the lead vehicle. This feedback loop enables the lead vehicle to make informed control decisions, improving remote control capability while maintaining independent operation on irregular roads.
