Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a trolley is designed with a single function as a working platform, then the structure is simple, but the versatility and degree of automation are low
Solution Approach 1:
The patent applies multi-functionality by integrating multiple construction devices (drilling device, excavation device, concrete spraying device) onto a single trolley platform. The trolley serves not only as a working platform but also as a mobile base for various construction operations, enabling one device to perform multiple functions that would traditionally require separate specialized equipment.
Solution Approach 2:
The patent combines previously separate construction devices into a single integrated trolley system. The drilling device, excavation device, and concrete spraying device are merged onto one trolley platform, allowing them to work together in coordinated operations. This merging reduces the number of separate pieces of equipment needed and improves overall system efficiency.
2Productivity
If multiple construction devices are integrated onto the trolley, then the functionality and efficiency are improved, but the device complexity increases
Solution Approach 1:
The patent segments the construction system into distinct functional modules: a drilling device for borehole creation, an excavation device for material removal, and a concrete spraying device for lining installation. Each module can be independently operated and maintained while working together on the same trolley platform, allowing for manageable complexity through modular design.
Solution Approach 2:
The patent introduces a control system as an intermediary that coordinates the operations of multiple construction devices on the trolley. This control system manages the complexity by providing centralized coordination, allowing the drilling, excavation, and concrete spraying operations to work together seamlessly through automated or semi-automated control mechanisms.
3Extent of automation
If the trolley is designed for automated operation, then the degree of automation is improved, but the initial complexity and cost increase
Solution Approach 1:
The patent implements self-service automation where the trolley system can autonomously position itself, deploy construction devices, and coordinate operations without continuous human intervention. The automated control system enables the trolley to navigate tunnel environments, position drilling and excavation devices accurately, and manage concrete spraying operations autonomously, reducing the need for manual operation while maintaining safety and precision.
