Leased Vehicle Maintenance Control Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle leasing services face challenges in maintaining the residual value of leased vehicles while avoiding excessive maintenance, as predetermined maintenance schedules may not align with individual driving conditions, leading to potential over-maintenance and decreased market value.
Innovation Solution
An information processing device that determines a recommended maintenance time period based on the vehicle's state, transmits this information to the user, and offers incentives for timely maintenance at a designated station, thereby encouraging appropriate maintenance without overburdening the lease service provider or degrading the vehicle's value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If predetermined maintenance schedules are implemented for leased vehicles, then maintenance reliability is improved, but excessive maintenance occurs leading to residual value decrease
Solution Approach 1:
The maintenance schedule is transformed from a static predetermined timeline to a dynamic system that adjusts based on actual vehicle usage conditions. The control unit receives usage information from the vehicle's sensor system and dynamically determines maintenance timing, allowing the schedule to adapt to individual driving patterns, load conditions, and environmental factors, thereby preventing both excessive and insufficient maintenance
Solution Approach 2:
A feedback mechanism is implemented where the control unit continuously monitors vehicle usage information and maintenance history, then adjusts future maintenance recommendations based on this data. The system provides feedback to the user through notifications and recommendations, creating a closed-loop system that learns from actual vehicle performance and usage patterns to optimize maintenance timing
2Reliability
If maintenance is performed frequently to maintain residual value, then vehicle condition is improved, but excessive maintenance cost increases
Solution Approach 1:
The system changes the parameters used to determine maintenance timing from fixed calendar-based intervals to variable parameters based on actual vehicle usage. By monitoring parameters such as mileage, operating hours, load conditions, and environmental factors, the system dynamically adjusts maintenance intervals to match actual wear and tear, preventing unnecessary maintenance while ensuring vehicle condition is maintained
3Loss of substance
If individualized maintenance schedules are implemented based on usage conditions, then residual value is maintained, but system complexity increases
Solution Approach 1:
The control unit is designed with multi-functionality, serving both as a usage information collector and a maintenance schedule determiner. The system integrates multiple functions including sensor data reception, usage pattern analysis, maintenance timing calculation, and user notification within a single control unit, reducing overall system complexity while enabling individualized maintenance schedules
Solution Approach 2:
The vehicle's own sensor system and control unit are utilized to collect and process usage information, eliminating the need for external monitoring systems. The system serves itself by automatically determining maintenance needs based on its own operational data, reducing the complexity of external intervention while maintaining accurate, individualized maintenance schedules

AI summary
In the information processing device, the control unit acquires a recommended time period in which maintenance of the leased vehicle is recommended at a predetermined station. The control unit transmits information including the recommended time period to a terminal associated with the user of the leased vehicle. The control unit outputs information of the reward provided to the user when the maintenance of the leased vehicle is performed at a predetermined station within the recommended time period.
