Solution Overview
Problem
Traditional cleaning trolleys lack digital communication capabilities, limiting users' access to information and real-time communication with cleaning centers, and do not provide a secure and protected environment for mobile communication devices.
Innovation Solution
A double-shell cleaning trolley design with a communication device holder that allows for easy integration of mobile devices, featuring a spring-damper system for easy lid operation, locks for security, and a touch-sensitive control panel for safe operation, ensuring the device is always online and protected from contamination and unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a mobile communication device is integrated into the cleaning trolley, then real-time communication and information access are enabled, but the device is exposed to contamination and unauthorized access
Solution Approach 1:
The communication device holder is nested within the intermediate space between the first and second shells, creating a protective layered structure. The holder is arranged in the intermediate space defined by the two shells, which can be folded away to open access or closed to protect the device from contamination and unauthorized access while maintaining communication capabilities
Solution Approach 2:
The support body is segmented into a two-shell unit with an outer first shell and an inner second shell, creating distinct functional zones. The intermediate space between shells houses the communication device holder, separating the communication function from the main cleaning trolley body while maintaining integrated operation
2Reliability
If the support body is designed as a two-shell unit with intermediate space, then the communication device holder is protected from external influences, but the structural complexity increases
Solution Approach 1:
The two-shell structure serves multiple functions simultaneously: it provides mechanical support for the communication device holder, creates a protective intermediate space, enables foldable access through the joint connection, and offers protection from contamination. This multi-functionality justifies the increased structural complexity by consolidating several protective and operational functions into a single integrated design
3Ease of operation
If the first and second shells can be folded away from one another, then access to the intermediate space is enabled, but the ease of operation is reduced
Solution Approach 1:
The connection between the first and second shells is designed as a joint that enables dynamic folding motion, allowing the structure to transition between closed protective state and open accessible state. This dynamic connection mechanism provides controlled access to the intermediate space while maintaining structural integrity and protection when closed
