Method for actively decreasing the temperature of a heatable soleplate in a textile treatment device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ironing devices risk damaging textiles if left stationary for prolonged periods without movement, as they continue to apply heat, leading to potential overheating and damage.
Innovation Solution
A textile treatment device equipped with a control unit and image sensor that classifies the textile type and adjusts the soleplate temperature and steam application dynamically, including actively cooling the soleplate if no movement is detected for a given duration to prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the soleplate temperature is maintained at a high level for efficient ironing, then the ironing efficiency is improved, but the risk of textile damage increases when the device is stationary
Solution Approach 1:
The control unit continuously monitors movement of the ironing device and uses this feedback to dynamically adjust the heating power. When movement is detected, normal heating continues; when stationary for a predetermined time, the control unit reduces heating power to prevent textile damage, thus resolving the contradiction between maintaining efficient temperature and preventing damage.
Solution Approach 2:
The heating control system transitions from a static temperature maintenance mode to a dynamic adjustment mode based on real-time movement detection. The heating power is continuously adapted according to the operational state (moving vs. stationary), allowing the system to optimize between ironing efficiency and damage prevention across different operating conditions.
2Stability of the object's composition
If the heating power is continuously applied to maintain soleplate temperature, then the temperature stability is improved, but the energy consumption increases during stationary periods
Solution Approach 1:
The heating system operates in periodic cycles rather than continuously. The control unit alternates between full heating power (when moving) and reduced heating power (when stationary), creating a periodic action pattern that maintains temperature stability during active use while reducing energy consumption during stationary periods.
Solution Approach 2:
The heating power parameter is dynamically changed based on the operational state. The control unit adjusts the heating power level from high (during movement) to low (during stationary periods), changing the operational parameter to optimize both temperature stability and energy efficiency across different usage scenarios.

AI summary
The invention relates to a method of operating a textile treatment device comprising a heatable soleplate intended to be in contact with a textile for treating the textile. The method comprises a first step (1001) of setting a first temperature target for the heatable soleplate, and a step (1002) of detecting movement of said textile treatment device. If the step (1002) of 5 detecting movement did not detect any movement of said textile treatment device during more than a given first time duration, a step (1004) of actively decreasing the temperature of the heatable soleplate (4) up to reaching a first given temperature having a value below said first temperature target.
