Electric Tool Load-Based Dust Collector Power Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric tool coordination systems, such as those involving dust collectors and polishing machines, face inefficiencies in energy consumption and noise due to auxiliary tools running at constant high power, leading to unnecessary waste and potential overload when the main tool's power requirements change.
Innovation Solution
An electric tool coordination system with a central control module that adjusts the power of auxiliary tools based on load parameters detected from the main tool, increasing power when the main tool's load increases and decreasing it when the load decreases, thereby optimizing energy use and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the auxiliary tool runs at constant high power to ensure sufficient suction, then the suction capability is improved, but energy consumption increases and noise is generated
Solution Approach 1:
The auxiliary tool's power is made dynamic rather than constant. The control module continuously monitors the main tool's operating state and adjusts the auxiliary tool's power accordingly, allowing it to operate at high power when needed and reduce power when the main tool's load decreases, thus resolving the contradiction between maintaining reliable suction and reducing energy consumption
Solution Approach 2:
A feedback mechanism is implemented where the detection module monitors the main tool's current and operating state, transmits this information to the central control module, which then adjusts the auxiliary tool's power based on the feedback signal. This closed-loop control ensures the auxiliary tool maintains sufficient suction capability while minimizing energy consumption during low-load periods
2Reliability
If the auxiliary tool runs at high power to handle dust generation, then the dust collection capability is improved, but noise increases
Solution Approach 1:
The auxiliary tool operates dynamically with variable power levels. When the main tool generates significant dust, the auxiliary tool runs at high power to maintain collection capability. When dust generation decreases, the auxiliary tool reduces power and consequently reduces noise output, resolving the contradiction between dust collection capability and noise generation
3Productivity
If the total power of main tool and auxiliary tool increases to handle high load, then the processing capability is improved, but the power supply device may overload
Solution Approach 1:
The detection module continuously monitors the main tool's current consumption and transmits this information to the central control module. The control module uses this feedback to determine when to activate or deactivate the auxiliary tool, ensuring the total power draw remains within the power supply device's safe operating limits while maintaining processing capability when conditions permit
Solution Approach 2:
The system dynamically changes the operating parameters (power level, on/off state) of the auxiliary tool based on the main tool's load conditions. When the main tool's current exceeds a threshold, the auxiliary tool is deactivated or reduced to prevent overload. When the main tool operates within safe limits, the auxiliary tool can be activated to enhance processing capability

AI summary
A combined electric tool coordination system includes a main tool (4) and an auxiliary tool (1). The main tool (4) and the auxiliary tool (1) coordinate for working. A load detection module (E1) is used to detect a load parameter that is generated when the main tool (4) operates, and send the load parameter to a central control module (E2). The central control module (E2) adjusts output power of the auxiliary tool (1). The central control module (E2) controls power of the auxiliary tool (1) to increase as the load parameter of the main tool (4) increases and decrease as the load parameter decreases. An automatic adjustment function of the auxiliary tool (1) is applied to a dust collector (1). When power of the main tool (4) increases, more dust and scraps are generated, suction of the dust collector (1) is automatically adjusted to be higher, and the demand of a large quantity of dust is satisfied; and when the power of the main tool (4) decreases, less dust and scraps are generated, power of the dust collector (1) automatically decreases, the suction is reduced, and the demand of a small quantity of dust is satisfied.
