Cleaning Trolley Plug-In Assembly for Tool-Free Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning trolleys are not easily adaptable to different application circumstances and are difficult to modify or disassemble once assembled, limiting their flexibility and recyclability.
Innovation Solution
A plug-in system with separately produced pillars and clamping or locking devices allows for tool-free assembly and disassembly of the cleaning trolley, enabling easy adaptation and modification by users, while ensuring stability and security through non-positive and positive connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cleaning trolley is assembled using traditional screwing or adhesive connection methods, then the structural stability and strength are improved, but the ease of disassembly and adaptability deteriorate
Solution Approach 1:
The cleaning trolley is divided into modular components (base plate, cover plate, side walls, partition walls, pillars) that can be independently assembled and disassembled. The plug-in system separates the connection mechanism into distinct plug and receptacle elements, enabling tool-free assembly while maintaining structural integrity through positive locking features.
Solution Approach 2:
The connection system transitions from static permanent joints (screws, adhesives) to dynamic reversible joints. The plug-in system allows the cleaning trolley to be easily reconfigured, disassembled, and reassembled multiple times while maintaining structural stability through positive locking mechanisms that provide firm connections during use.
2Ease of manufacture
If the cleaning trolley is designed as a fixed structure, then the manufacturing precision and assembly simplicity are improved, but the adaptability to different application circumstances deteriorates
Solution Approach 1:
The plug-in system design allows the same basic components (base plate, cover plate, pillars) to serve multiple functions and configurations. The standardized plug and receptacle interfaces enable different side walls and partition walls to be interchangeably assembled, allowing the cleaning trolley to adapt to various application circumstances while maintaining simple manufacturing processes.
3Strength
If traditional connection methods are used, then the structural strength is improved, but the ease of operation and user-friendly assembly deteriorate
Solution Approach 1:
The plug-in system enables users to assemble and disassemble the cleaning trolley themselves without requiring tools or specialized skills. The design incorporates self-aligning features and intuitive plug-and-receptacle interfaces that guide users through the assembly process, making it as simple as inserting and connecting components while maintaining strong structural connections.
