Solution Overview
Problem
Suction devices, especially battery-operated ones, face overheating issues when operating at high ambient temperatures or on thick carpets, leading to reduced battery life due to inefficient air movement and existing solutions like secondary air valves or temperature-controlled shutdowns.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If secondary air valves are used to release additional ambient air for cooling, then motor overheating is prevented, but battery life is reduced due to unusable air movements
Solution Approach 1:
The control device dynamically adjusts motor operating parameters (speed, power, torque) based on real-time temperature measurements from the temperature sensor. When temperature exceeds thresholds, the control device modifies these parameters to reduce heat generation while maintaining acceptable performance, thereby preventing overheating without wasting battery energy on ineffective air movement adjustments
2Reliability
If the suction device is switched off when temperature becomes too great, then components are protected from overheating, but operation is interrupted and battery life is reduced
Solution Approach 1:
The control device continuously monitors temperature via the temperature sensor and uses this feedback to dynamically adjust motor operating parameters. This closed-loop control allows the system to operate continuously by modulating performance rather than shutting off, protecting components from overheating while maximizing continuous operation time and battery utilization
3Productivity
If motor operates at high power to maintain suction performance, then cleaning efficiency is improved, but heat generation increases causing component overheating
Solution Approach 1:
The control device dynamically adjusts motor operating parameters (speed, power, torque) based on real-time temperature measurements from the temperature sensor. When temperature exceeds thresholds, the control device modifies these parameters to reduce heat generation while maintaining acceptable performance, thereby preventing overheating without wasting battery energy on ineffective air movement adjustments
