Dust Collector Interlock Control for Machine-Specific Pairing
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 an interlock operation control portion that uses identification information stored in a storage portion to determine whether an electric working machine requires interlock operation, based on an interlock command received, and can register or delete this information, ensuring proper operation only with machines that need it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dust collector starts interlock operation upon receiving 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 start notification to the electric working machine, and the interlock operation is executed only when the machine responds with an interlock operation start instruction. This feedback mechanism ensures that both devices are ready and agree to the interlock operation, preventing inadvertent activation while maintaining ease of initiation.
Solution Approach 2:
The control portion acts as an intermediary by receiving the initial interlock operation start signal, verifying the machine's readiness through feedback communication, and then executing the operation only after confirmation. This intermediary role adds a verification layer that improves reliability without significantly complicating the initiation process.
2Adaptability or versatility
If the dust collector performs interlock operation with any electric working machine that transmits a signal, then the system is highly adaptable to different machines, but the dust collector cannot distinguish between machines that require interlock operation and those that do not
Solution Approach 1:
The system uses bidirectional feedback communication where the dust collector sends a start notification and the electric working machine responds with a confirmation instruction. This feedback loop enables precise identification of machines that require interlock operation, as only authorized machines will respond with the correct confirmation signal, thus resolving the contradiction between adaptability and identification precision.
3Device complexity
If the dust collector uses wireless communication for interlock operation, then the system complexity is reduced and cordless machine compatibility is improved, but the ability to reliably identify and distinguish target machines is weakened
Solution Approach 1:
The wireless communication system implements a feedback mechanism where the dust collector transmits an interlock operation start notification and the electric working machine responds with a confirmation instruction. This simple yet effective feedback loop ensures reliable machine identification and interlock operation execution without requiring complex wired connections or additional hardware, maintaining low system complexity while improving reliability.

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.
