Dust collector interlocking system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collector interlocking systems often malfunction when multiple systems are used in the same work site due to interference from strong radio signal outputs, causing operational issues with other interlocking systems.
Innovation Solution
The dust collector interlocking system places a receiver on the suction hose near the electric power tool, minimizing the distance between the transmitter and receiver, allowing for weak signal reception without interfering with other systems, and adjusts the transmitter output to match the suction hose length to reduce power consumption and minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmitter output is increased to ensure reliable radio signal reception over distance, then the reception reliability is improved, but interference with other interlocking systems increases
Solution Approach 1:
The receiver is strategically positioned at the distal end of the suction hose, which is the location closest to the electric power tool and transmitter. This local placement ensures that the radio signal is received at the optimal location with minimal transmission distance, allowing the use of low transmitter output without compromising reception reliability.
2Device complexity
If the receiver is placed near the dust collector main body to reduce wiring length, then the device complexity is reduced, but the radio signal reception may be insufficient
Solution Approach 1:
Instead of reducing wiring length by placing the receiver near the main body, the invention extends the receiver placement along the spatial dimension of the suction hose to the distal end. This dimensional adjustment prioritizes radio signal reception reliability over wiring minimization, accepting longer wiring as a necessary trade-off for reliable operation.
3Object-affected harmful factors
If the transmitter output is reduced to minimize interference with other systems, then the harmful factors are reduced, but the reception reliability may deteriorate
Solution Approach 1:
The receiver is pre-positioned at the distal end of the suction hose before operation begins. This preliminary placement ensures that the receiver is already in the optimal position to capture the radio signal when the transmitter operates at low output, preventing signal loss that would occur if the receiver were positioned elsewhere.
