Solution Overview
Problem
Existing rolling devices for moving objects along surfaces are complex to disassemble and assemble for component replacement, requiring skilled expertise and increasing maintenance costs, especially since the rolling elements are prone to wear and need frequent replacement.
Innovation Solution
A rolling device with a housing that accommodates a control and communication module, driving means, and a releasable support assembly for the rolling element, allowing easy detachment and reattachment by a user, using wireless control and position acquisition for movement instructions, and featuring a drive motor for displacing the rolling element between extended and retracted positions, facilitating simple and cost-effective replacement of the rolling element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rolling device uses a complex mechanical structure with multiple interacting components, then the device achieves reliable movement and positioning, but the complexity of disassembly and assembly for component replacement increases significantly
Solution Approach 1:
The rolling device is divided into distinct modular components: a housing containing the control and communication module, and a separate rolling element assembly. This segmentation allows the rolling element to be replaced independently without disassembling the entire device, resolving the contradiction by maintaining system reliability while simplifying maintenance procedures.
Solution Approach 2:
The rolling element is extracted as a separate replaceable component from the housing. The housing accommodates the rolling element but allows it to be removed and replaced independently, enabling users to replace worn rolling elements without dealing with the complex interacting mechanical components inside the housing.
2Manufacturing precision
If the rolling device requires skilled expertise for component replacement, then the device maintains high manufacturing precision and reliability, but the maintenance costs increase and accessibility for average users decreases
Solution Approach 1:
The rolling element assembly is segmented from the housing as a independent module. This segmentation enables users without specialized expertise to replace the rolling element by simply removing and installing the modular assembly, while the precision-engineered interfaces ensure proper fit and function are maintained.
Solution Approach 2:
The design enables self-service replacement of the rolling element by average users. The rolling element assembly is configured to be easily removed and installed by users without requiring skilled mechanical expertise, while maintaining the manufacturing precision needed for reliable operation.
3Reliability
If the rolling element is frequently replaced due to wear, then the device maintains reliable operation, but the maintenance costs and time consumption increase
Solution Approach 1:
The rolling element is segmented as a separate wear component that can be quickly replaced without disassembling the housing or other mechanical components. This segmentation reduces replacement time significantly compared to integrated designs where the rolling element is part of a complex mechanical assembly requiring multiple disassembly steps.
Solution Approach 2:
The rolling element assembly is designed as a pre-assembled modular unit ready for installation. This preliminary preparation of the replacement component allows users to simply swap the assembly without performing complex assembly procedures, reducing both time and complexity of the replacement process.
