Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor processing devices lack a reliable method to indicate successful operation and alert users to potential malfunctions, particularly in terms of fragrance emission and wear part replacement.
Innovation Solution
A motor-driven floor processing device with a fragrance element housed in a hollow space that emits fragrance molecules through openings due to air movement, synchronized with the operation and wear life of the processing element, and featuring a mechanically activatable valve to control fragrance release based on centrifugal force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fragrance element is placed in the hollow space of the floor processing element, then the indication of successful operation and malfunction alerting is improved, but the device complexity increases
Solution Approach 1:
The fragrance element serves itself by utilizing the centrifugal force generated during normal operation of the floor processing element to automatically emit fragrance. No additional power source, control system, or actuation mechanism is required - the system leverages the existing operational motion to activate the fragrance emission function.
Solution Approach 2:
The hollow space acts as an intermediary chamber that houses the fragrance element and facilitates fragrance emission. The hollow space opening serves as the interface between the enclosed fragrance storage and the ambient environment, allowing fragrance molecules to be released during operation without requiring complex delivery mechanisms.
2Productivity
If the hollow space opening is made larger to facilitate fragrance emission, then the fragrance emission efficiency is improved, but the fragrance leakage during non-operation increases
Solution Approach 1:
The system transitions from a static opening design to a dynamic one where the effective opening size changes based on operational state. During operation, centrifugal force actively opens the hollow space opening for efficient fragrance emission. During non-operation, the opening remains closed or minimal, preventing fragrance leakage. This dynamic adaptation resolves the contradiction between emission efficiency and leakage prevention.
3Stability of the object's composition
If the fragrance element is fixed in the hollow space, then the structural stability is improved, but the ease of replacement decreases
Solution Approach 1:
The fragrance emission system is segmented into separable components: the hollow space (integrated into the floor processing element) and the fragrance element (removable). This segmentation allows the fragrance element to be easily replaced by the user while maintaining structural stability during operation. The detachable design enables maintenance and replacement without requiring disassembly of the entire floor processing element.
