Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote maintenance systems for construction machinery are limited in their ability to repair mechanical components, require specialized technicians, and pose data security concerns, especially when dealing with sensitive information from multiple manufacturers.
Innovation Solution
A system utilizing a 3D printer and augmented reality device at the construction site, facilitated by a data supply station that provides authenticated component data and repair information, allowing on-site repair of various construction machines without exposing sensitive data, and using a multi-stage authentication process for secure data access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote maintenance station is connected via data communication link to query operating data and input data sets, then maintenance and software updates can be performed remotely, but mechanical components cannot be repaired, removed, installed, or replaced
Solution Approach 1:
A 3D printer is introduced as an intermediary device between the remote maintenance station and the mechanical components. The printer receives component data from the maintenance station via communication link and locally manufactures the required mechanical parts, enabling physical repair capabilities without requiring on-site specialized technicians or complex logistics
Solution Approach 2:
Instead of physically transporting the original mechanical components or specialized tools to the remote site, the system creates digital copies of the component data from the maintenance station and uses these copies to manufacture replacement parts locally at the construction site
2Ease of repair
If detailed component data is provided to enable 3D printing of spare parts, then on-site repair capability is improved, but data security risks increase due to sensitive design data from manufacturers
Solution Approach 1:
The system extracts only the necessary component data required for 3D printing specific spare parts from the comprehensive manufacturer databases. By requesting and transmitting only the minimal required data (component geometry, dimensions, material specifications) rather than all design data, the system enables on-site repair capability while minimizing data security exposure
Solution Approach 2:
The data structure is segmented into multiple levels: manufacturer databases contain comprehensive design data, intermediate data stations hold processed component data, and local maintenance stations store only the specific 3D printing data needed for immediate repairs. This segmentation isolates sensitive manufacturer data from the 3D printing process while maintaining necessary repair capabilities
3Adaptability or versatility
If multiple individual data access points from different manufacturers are provided to obtain maintenance data, then comprehensive maintenance capability is achieved, but system complexity and data management burden increase
Solution Approach 1:
The maintenance station is designed with universal data access capabilities that work across multiple manufacturers' systems through standardized communication protocols. A single maintenance station can query, receive, and process component data from various manufacturers without requiring separate specialized interfaces for each manufacturer, thereby reducing system complexity while maintaining comprehensive multi-manufacturer support
