Solution Overview
Problem
Existing handheld vacuum cleaners lack the ability to control the intensity of suction force and often have operation switches that can be accidentally activated during use, leading to inefficient cleaning and potential user discomfort.
Innovation Solution
A cleaner design featuring a support frame with a first push part for turning the suction motor on/off and a second push part for adjusting suction intensity, positioned higher than the handle to prevent accidental operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the trigger switch is positioned on the handle for easy operation, then the ease of operation is improved, but the reliability deteriorates due to accidental activation
Solution Approach 1:
The operation unit is repositioned from the handle area to the upper portion of the main body, changing its spatial location to a dimension less accessible during normal cleaning operations. This dimensional relocation prevents accidental activation while preserving intentional control capability.
2Device complexity
If only a simple on/off switch is provided, then the device complexity is reduced, but the adaptability deteriorates as suction intensity cannot be controlled
Solution Approach 1:
The operation unit serves multiple functions: it acts as both an on/off switch and an intensity controller. By integrating these functions into a single component with different operational modes (pressing for on/off, rotating for intensity), the device achieves multi-functionality without proportionally increasing complexity.
Solution Approach 2:
The operation unit transitions from a static on/off switch to a dynamic control mechanism that allows continuous adjustment of suction intensity through rotation. This dynamic capability enables the device to adapt to varying cleaning requirements while maintaining a relatively simple overall structure.
3Ease of operation
If the operation unit is positioned on the handle, then the ease of operation is improved, but the reliability worsens due to unexpected operation during cleaning
Solution Approach 1:
The operation unit is repositioned from the handle area to the upper portion of the main body, changing its spatial location to a dimension less accessible during normal cleaning operations. This dimensional relocation prevents accidental activation while preserving intentional control capability.

AI summary
A cleaner includes: a suction motor that generates a suction force; and an operation unit that is configured to input control instruction for the suction motor.The operation unit includes: a support frame; a first push part that is rotatably seated on the support frame and allows an instruction to turn on or off the suction motor to be input when being rotated in a first direction; and a second push part that allows the intensity of the suction force of the suction motor to be adjusted when being rotated in a second direction.
