Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transfer systems in existing technologies experience increased noise and energy loss due to the switching of inverter circuits during runtime.
Innovation Solution
The system includes a plurality of transfer path units where the inverter circuits are switched only when a transferring body is present, and the switching is stopped when the body is absent, reducing noise and energy loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inverter circuits are switched continuously during runtime, then the transfer system can maintain readiness to move the transferring body, but noise and energy loss increase
Solution Approach 1:
The patent applies dynamics by making the switching state of inverter circuits adjustable based on real-time operational needs. The control device dynamically switches inverter circuits on or off depending on whether the transferring body is present in each transfer path unit, transitioning the system from a static continuous-switching state to a dynamic conditional-switching state that adapts to operational requirements.
Solution Approach 2:
The patent applies local quality by enabling different switching states in different spatial locations (transfer path units). Instead of uniformly switching all inverter circuits continuously, the system applies switching locally only to units where the transferring body is present, while leaving other units in an off state, thereby reducing overall noise while maintaining local readiness where needed.
2Reliability
If inverter circuits are switched continuously during runtime, then the transfer system can maintain readiness to move the transferring body, but energy loss increases
Solution Approach 1:
The control device dynamically adjusts the switching state of inverter circuits based on the presence of the transferring body. When no transferring body is detected in a transfer path unit, the inverter circuit is switched off, eliminating continuous energy consumption while maintaining the capability to quickly resume operation when needed.
Solution Approach 2:
The system applies energy-saving switching locally to individual transfer path units rather than uniformly across the entire system. Each unit independently switches its inverter circuit based on local presence detection, reducing total energy loss while maintaining operational readiness only where required.
3Loss of energy
If inverter circuits are switched only when transferring body is present, then noise and energy loss are reduced, but system complexity increases due to presence detection and conditional control
Solution Approach 1:
The control device performs multiple functions: it detects the presence of the transferring body, determines which inverter circuits should be switched, and controls the switching operation. This multi-functionality consolidates what could be separate complex systems into a single integrated control unit, managing the added complexity through functional integration.
Solution Approach 2:
The system uses the existing infrastructure (control device and presence detection capability) to automatically manage the conditional switching of inverter circuits. The control device self-regulates the switching based on detected conditions without requiring external intervention or additional complex control mechanisms.

AI summary
A transfer system includes a plurality of transfer path units that forms a transfer path, on which a transferring body moves, and causes the transferring body to move by giving power to the transferring body. Each of the plurality of the transfer path units includes: a drive unit that generates the power; and an inverter circuit that includes a switching element and supplies, to the drive unit, electric power obtained through electric power conversion by switching of the switching element. In a portion of the transfer path where the transferring body is absent, at least one of one or two or more of the transfer path units in the portion stops the switching.
