Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld cleaners in the related art are cumbersome due to their large size and weight, have limited dust capacity, short cleaning duration, and complex structures, leading to bacterial growth and odor issues, which reduce their overall effectiveness.
Innovation Solution
A compact dust cup assembly with a large dust capacity, featuring a negative pressure device, a dedusting device, and a cyclone assembly, integrated with a handle for easy handling, and a control system that adjusts suction strength based on motion and dust concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the cleaner is designed with large volume to increase dust capacity, then the dust capacity is improved, but the weight and portability deteriorate
Solution Approach 1:
The dust cup assembly is nested within the handle assembly, with the dust cup positioned inside the hollow cylindrical structure of the handle. This nesting arrangement allows the dust collection function to be integrated into the handle structure itself, increasing dust capacity without proportionally increasing overall volume or weight.
Solution Approach 2:
The patent utilizes the longitudinal dimension of the handle by extending the dust cup along the length of the handle assembly. Rather than expanding dust capacity radially (which would increase width and portability issues), the design extends the dust collection chamber along the longitudinal axis, effectively using available space in a different dimensional direction.
2Productivity
If the cleaner structure is made complex to improve cleaning performance, then the cleaning effect is improved, but the ease of cleaning and maintenance deteriorates
Solution Approach 1:
The cleaner is divided into separable modules: the dust cup assembly can be detached from the handle assembly, and the filter element can be removed from the dust cup. This segmentation allows users to easily access and clean individual components without disassembling the entire device, maintaining ease of cleaning while enabling sophisticated cleaning functions through the integrated cyclone separation system.
Solution Approach 2:
The filter element is designed as a separate, extractable component that can be removed from the dust cup for cleaning. The dust cup itself can be extracted from the handle assembly. This extraction capability simplifies maintenance of complex internal components like the cyclone separators and filtration systems.
3Duration of action of moving object
If the cleaner runs for extended period to increase sustainable cleaning time, then the cleaning duration is improved, but the dust capacity is depleted faster
Solution Approach 1:
The cyclone separation system provides continuous dust separation throughout the cleaning operation, maintaining consistent suction performance. The design ensures that dust is continuously removed from the airflow path and collected in the dust cup, preventing performance degradation over time and enabling sustained cleaning operation without frequent capacity depletion.
