Solution Overview
Problem
Existing cleaning devices for floors require external energy sources for heating and tempering cleaning liquids, leading to uncomfortable and expensive handling, as well as potential temperature drops and internal pressure issues due to steam generation.
Innovation Solution
A wireless cleaning device with a thermally insulated dispensing device and a heat accumulator that maintains the cleaning liquid at a desired temperature, using a heat accumulator to store and release heat independently of an external energy source, and an electrical resistance heater that can operate without cables, ensuring efficient heating and evaporation without high pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cable-connected heating device is used to heat cleaning liquid, then heating function is achieved, but handling becomes uncomfortable and expensive
Solution Approach 1:
The heating device is extracted from the external cable-connected system and integrated into the portable cleaning device itself, allowing the heating function to be self-contained and mobile without requiring external power sources or cables during operation
Solution Approach 2:
The cleaning device performs its own heating function through an integrated heating element powered by an internal power source, eliminating the need for external service or cable connections during use
2Ease of operation
If the cleaning device is made portable and wireless, then ease of operation improves, but energy supply for heating becomes problematic
Solution Approach 1:
The power source transitions from external mains power to an internal battery system, changing the energy supply parameters to enable portable wireless operation while maintaining heating capability
Solution Approach 2:
The integrated power source serves multiple functions: powering the heating element, the pump, and other electronic components of the portable cleaning device, consolidating energy supply needs into a single battery system
3Speed
If heating power is increased to heat cleaning liquid quickly, then heating speed improves, but internal pressure increases due to steam generation
Solution Approach 1:
A temperature sensor continuously monitors the cleaning liquid temperature and provides feedback to the control unit, which adjusts the heating power accordingly to prevent excessive temperature rise and steam generation that would increase internal pressure
Solution Approach 2:
The heating element is designed to provide sufficient but not excessive heating power, delivering enough heat to maintain cleaning liquid at effective temperatures without generating excessive steam that would dangerous internal pressure buildup
4Stability of the object's composition
If thermal insulation is added to prevent temperature drop, then temperature stability improves, but device complexity increases
Solution Approach 1:
Thermal insulation is pre-applied to the cleaning liquid container to prevent heat loss before temperature control issues arise, maintaining stable cleaning liquid temperature passively without requiring additional active temperature regulation mechanisms
