Modular Electric Drive Tractor Power and Work Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional work machines, such as track-type tractors, have a high number of integrated parts and connections, making maintenance and testing cumbersome and time-consuming, as individual components like engines and batteries cannot be easily accessed or removed for service without disassembling the entire machine.
Innovation Solution
The machine is designed with modular components, including a power module with a folding heat exchange device, a drive module over a track roller frame, and separate hydraulic and ripping modules, allowing for easy access, removal, and maintenance of individual parts without affecting the rest of the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If parts are integrated within the work machine as a self-contained assembly, then structural compactness is improved, but maintenance access and component removal become cumbersome
Solution Approach 1:
The work machine is divided into separate modular assemblies including a power module (engine and battery), a work module (blade or ripper), and a chassis. Each module can be independently removed and serviced without disassembling the entire machine, resolving the contradiction between structural compactness and maintenance access.
2Adaptability or versatility
If multiple connections and interface points are integrated within the machine, then functional integration is improved, but maintenance time and complexity increase
Solution Approach 1:
The machine uses standardized interface points and connections between modular assemblies that allow for quick connection and disconnection. This enables functional integration during operation while significantly reducing maintenance time when modules need to be removed or serviced.
3Reliability
If the entire work machine is taken to a maintenance facility for component service, then component maintenance is ensured, but productivity and operational time are reduced
Solution Approach 1:
The power module, work module, and other components are designed to be extractable from the chassis. This allows maintenance to be performed on removed modules at a facility while the remaining machine structure can be quickly reconfigured or returned to service, minimizing productivity loss.
4Strength
If parts cannot be separately removed from the work machine, then structural integrity is maintained, but serviceability and testing become tedious
Solution Approach 1:
The machine is segmented into modular assemblies connected through standardized interfaces that maintain structural integrity during operation but allow for easy separation during maintenance. Each module can be independently serviced or tested without compromising the overall structural integrity of the machine when reassembled.
