Sensor mounting structure and cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices, such as sweeping robots, have independent liquid storage tanks with high production costs, poor consistency, and a high risk of accidents due to frequent disassembly and assembly, affecting their appearance and service life.
Innovation Solution
The integration of the liquid storage tank's bottom shell and main body into a single, integral structure, facilitated by injection molding, reduces parts and assembly steps, and uses ultrasonic welding for a strong molecular bond between the bottom shell and upper cover, enhancing reliability and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the liquid storage tank is designed as an independent detachable component, then it is easy to assemble and disassemble for maintenance, but the production cost increases, appearance quality deteriorates, and the risk of accidents increases due to frequent disassembly and assembly
Solution Approach 1:
The patent merges the liquid storage tank with the main body into an integral structure, eliminating the need for separate assembly and disassembly of the tank. This integration removes the risk of accidents associated with frequent detachment while maintaining ease of maintenance through other means such as removable caps or access points.
2Ease of operation
If the liquid storage tank is designed as an independent detachable component, then it is easy to assemble and disassemble for maintenance, but the production cost increases
Solution Approach 1:
The patent combines the liquid storage tank and main body into a single integrated structure, reducing the number of parts and assembly steps. This integration lowers production costs by eliminating separate manufacturing and assembly processes for the tank, while maintaining ease of maintenance through alternative design features.
3Ease of operation
If the liquid storage tank is designed as an independent detachable component, then it is easy to assemble and disassemble for maintenance, but the appearance quality deteriorates
Solution Approach 1:
The patent integrates the liquid storage tank with the main body to create a seamless, unified appearance. This integration eliminates visible seams, joints, and fasteners that would compromise aesthetic quality, while maintenance accessibility is preserved through other design mechanisms such as removable covers or access panels.
4Ease of repair
If the liquid storage tank is designed as an independent detachable component, then it can be easily maintained, but the service life is reduced due to frequent disassembly and assembly
Solution Approach 1:
The patent merges the liquid storage tank with the main body to eliminate repeated assembly and disassembly cycles, thereby extending the service life of the device. Maintenance is still facilitated through alternative approaches such as modular components, removable caps, or access points that do not compromise the integral structure.
