Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices, such as vacuum cleaners, require manual button operation which can lead to malfunctions, are cumbersome for elderly users, and lack intuitive control mechanisms.
Innovation Solution
Implementing a tactile sensor system on the handle of the cleaning device to detect user touch, pressure, and position, allowing for adaptive control and eliminating the need for physical buttons, with features like automatic activation/deactivation and mode selection based on user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contactless communication is used between handle and cleaning head, then hygiene is improved by preventing cross-contamination, but reliability deteriorates due to signal interference from dirty surfaces
Solution Approach 1:
A magnetic field is introduced as an intermediary for data transmission between the handle and cleaning head, replacing direct contactless communication. The magnetic field penetrates dirty surfaces without being blocked by contamination, enabling reliable communication while maintaining the hygiene benefits of contactless operation.
Solution Approach 2:
The communication method is changed from electromagnetic radio waves to magnetic field coupling. This parameter change in the physical medium enables transmission through contaminated environments while maintaining contactless operation, thus improving both reliability and hygiene.
2Ease of operation
If tactile sensor device is added to handle, then ease of operation is improved through intuitive touch control, but device complexity increases
Solution Approach 1:
The tactile sensor device enables the user to directly interact with and control the cleaning device through natural touch gestures on the handle. The system interprets user intent through simple touch patterns (duration, position, repetition) without requiring complex interfaces or training, making the device serve itself through intuitive human interaction.
Solution Approach 2:
Physical mechanical controls (buttons, switches, dials) are replaced with a tactile sensor system that detects touch gestures. This substitution provides more intuitive control while consolidating multiple control functions into a single sensor device, actually reducing overall control system complexity.
