Intelligent hand cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent hand cleaners are inconvenient to assemble and disassemble, and it is troublesome for users to replace the internal hand sanitizer, which hampers user convenience and disease prevention.
Innovation Solution
An intelligent hand cleaner design featuring a sensor-activated driving assembly that dispenses liquid without manual pressing of the pump head, combined with a positioning clamping bulge and slot for easy assembly and disassembly, and optional wall-mounted or support configurations for versatile use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pressing of the pump head is used to dispense liquid, then the structure is simple, but user convenience deteriorates and hand contact increases
Solution Approach 1:
The patent replaces the manual mechanical pressing operation with an automated driving assembly that includes a motor, transmission mechanism, and pressing component. The sensor detects user approach and triggers the driving assembly to automatically press the pump head, eliminating the need for direct hand contact with the pressing head while maintaining the liquid dispensing function.
Solution Approach 2:
The system performs self-service by automatically detecting user presence through the sensor and initiating the liquid dispensing process without requiring manual intervention. The driving assembly autonomously completes the pressing action, reducing hand contact and improving hygiene while maintaining operational simplicity for the user.
2Ease of manufacture
If the container is permanently fixed in the mounting seat, then assembly is simple, but disassembly and refilling become troublesome
Solution Approach 1:
The patent divides the hand cleaner into separable modules: the mounting seat with connecting port, the container with connector, and the pressing pump assembly. The connector and connecting port feature positioning clamping structures that enable easy assembly and disassembly. Users can detach the container from the mounting seat for refilling or replacement without complex tools or procedures.
3Ease of manufacture
If the connector design lacks positioning structures, then manufacturing is simpler, but assembly precision and reliability deteriorate
Solution Approach 1:
The patent incorporates asymmetric positioning clamping structures including positioning clamping bulges on the connector and corresponding positioning clamping slots on the connecting port. These asymmetric features guide the container into the correct orientation during assembly and prevent misalignment, ensuring reliable connection while maintaining manufacturing simplicity through straightforward molding processes.
