Dust Collector Interlock Control Using Machine Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dust collectors may inadvertently start an interlock operation with multiple electric working machines, leading to unintended operation when not all machines require interlock functionality, due to the lack of specific identification and control mechanisms.
Innovation Solution
A dust collector with a communication unit and interlock operation control portion that uses identification information to determine which electric working machines require interlock operations, allowing for precise control and registration of these machines, and includes features like periodic signal transmission and error prevention mechanisms to ensure accurate operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dust collector starts interlock operation upon receipt of a single transmitted signal from an electric working machine, then the interlock operation can be initiated easily, but the dust collector may be operated inadvertently by signals from machines that do not require interlock operation
Solution Approach 1:
The dust collector transmits an interlock operation response signal back to the electric working machine upon receiving an interlock operation start signal. This feedback mechanism allows the system to confirm the identity and compatibility of the working machine before activating the interlock operation, preventing inadvertent activation while maintaining ease of operation initiation
Solution Approach 2:
The control portion acts as an intermediary that mediates between the transmitted interlock operation start signal and the actual activation of the interlock operation. It verifies the signal's validity and the machine's compatibility before permitting operation, thus ensuring reliability without complicating the initiation process
2Reliability
If the dust collector uses identification information to determine which machines require interlock operations, then the accuracy of interlock operation activation is improved, but the device complexity increases due to storage portion and verification mechanisms
Solution Approach 1:
The control portion performs multiple functions: receiving interlock operation start signals, transmitting response signals, verifying identification information, and controlling interlock operation activation. By consolidating these functions into a single control portion, the patent avoids the need for separate dedicated components for each function, thereby managing device complexity while maintaining high reliability
Solution Approach 2:
The system uses identification information as a parameter to determine whether to activate interlock operation. By changing the control parameter from a simple signal presence check to an identification-based verification, the system achieves higher reliability without proportionally increasing complexity, as the verification process integrates into the existing control architecture

AI summary
A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.
