Solution Overview
Problem
Current non-contact power feed systems for mobile objects lack improvements in convenience and functionalization, particularly in efficiently managing power transmission and operation within defined areas.
Innovation Solution
A mobile object apparatus equipped with an electric power reception unit, a drive unit, and an electric power storage unit, which receives and stores power from adjacent power feed apparatuses in a non-contact manner, allowing for controlled movement and operation within a predetermined area, with control units managing power transmission and operation restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If non-contact power feed system is used with multiple power feed apparatuses allocated to small areas, then power transmission efficiency and operational flexibility are improved, but system complexity increases
Solution Approach 1:
The predetermined area is divided into multiple small areas, with each power feed apparatus responsible for a specific small area. This segmentation allows the mobile object apparatus to receive power efficiently from the nearest apparatus while maintaining system manageability through localized power zones.
Solution Approach 2:
The system dynamically selects which power feed apparatus supplies power based on the mobile object apparatus's current position and movement direction. The control unit determines optimal power reception from adjacent small areas, enabling flexible adaptation to changing operational conditions without fixed power supply points.
2Ease of operation
If electric power storage unit stores power for movement to small areas within predetermined range, then operational autonomy and convenience are improved, but device weight and size increase
Solution Approach 1:
The electric power storage unit stores only the minimum necessary power required for movement to adjacent small areas within a predetermined range, rather than storing enough power for the entire predetermined area. This partial charging approach provides sufficient operational autonomy for practical use while minimizing battery capacity, weight, and size.
3Reliability
If control unit manages power transmission with temporal and spatial conditions, then security and power management are improved, but control complexity increases
Solution Approach 1:
Different control rules are applied to different spatial zones (small areas) within the predetermined area. Each small area has specific temporal and spatial conditions for power transmission, allowing security measures to be tailored to local requirements rather than applying uniform complex controls across the entire system.
4Reliability
If power feed apparatuses are allocated to specific small areas, then power transmission reliability is improved, but system adaptability decreases
Solution Approach 1:
While power feed apparatuses are allocated to specific small areas for reliable localized power transmission, the system dynamically adapts to mobile object apparatus movement by switching power supply sources between adjacent small areas. This dynamic reconfiguration maintains reliability within each zone while providing system-level adaptability to changing operational needs.
