Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a step-shaped elevating device is mounted to assist driver boarding and alighting, then driver safety and ease of operation are improved, but device complexity, size, weight, and manufacturing cost increase
Solution Approach 1:
The patent replaces the mechanical elevating device with an image processing system that uses cameras and algorithms to detect driver posture and provide guidance. This substitutes complex mechanical structures with electronic sensing and computational methods, reducing device complexity while maintaining the safety function.
Solution Approach 2:
The patent introduces an image processing system as an intermediary between the driver and the boarding process. Instead of directly providing mechanical assistance through elevating devices, the system uses image analysis to detect posture and provides guidance information, acting as a mediating layer that enables safety without mechanical complexity.
2Reliability
If a step-shaped elevating device is mounted to assist driver boarding and alighting, then driver safety is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive mechanical elevating devices with more cost-effective image processing technology. By using cameras and software algorithms to monitor and guide driver posture, the system achieves safety objectives without the high manufacturing costs associated with mechanical elevation systems.
Solution Approach 2:
The patent uses image copying technology to create a digital representation of the driver's posture. By capturing and analyzing images of the driver's position, the system can assess safety without requiring physical mechanical interventions, thereby reducing manufacturing costs while maintaining reliability.
3Ease of operation
If a step-shaped elevating device is mounted to assist driver boarding and alighting, then ease of operation is improved, but device size and weight increase
Solution Approach 1:
The patent replaces heavy mechanical elevating devices with lightweight image processing equipment. By using cameras and computational algorithms instead of mechanical structures, the system maintains ease of operation guidance while significantly reducing the added weight to the work machine.

AI summary
Provided is to suppress addition of configurations and to make boarding and alighting of a driver of a work machine (100, 100A) appropriate. An acquisition unit (40) configured to acquired posture information indicating a posture of the driver of the work machine (100, 100A) when boarding and alighting, a transmission unit (31) configured to transmit the posture information to an outside of the work machine (100, 100A), and a determination unit (33, 34, 211, 212) configured to determine appropriateness of the posture when boarding and alighting based on the received posture information are included to detect boarding and alighting in an inappropriate posture such as two-point support or directing a body toward the outside, make notification in a recognizable manner, and transmit to the outside of the work machine (100, 100A), so that occurrence thereof is suppressed.
