Construction Machine Layout Flexibility via Driver Seat Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction machines, such as hydraulic excavators, have limited layout flexibility due to the presence of a driver's seat, restricting their operational capabilities and multifunctionality.
Innovation Solution
A construction machine design that includes a movable main body, a conveyance device for excavated objects, and a processing device for modifying these objects, allowing for unmanned operation and enhanced layout flexibility through the use of drones and advanced processing systems like near-infrared moisture meters and liquid supply systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a driver's seat is provided in the construction machine, then the operator can control the machine, but the layout flexibility and degree of freedom in machine configuration is limited
Solution Approach 1:
The patent removes the driver's seat and operator cabin from the construction machine, extracting the human operator element entirely. This allows the machine body to be configured without the spatial and structural constraints imposed by a cab, enabling greater layout freedom and adaptability for different working environments and functions.
Solution Approach 2:
The construction machine is equipped with automated excavation, conveyance, and processing systems that perform functions previously requiring human operators. The machine serves itself through integrated control systems, sensors, and automated mechanisms, eliminating the need for a driver's seat while maintaining full operational capability.
2Adaptability or versatility
If the construction machine is designed for traditional excavation only, then the machine structure is simple, but the multifunctionality is reduced
Solution Approach 1:
The patent integrates multiple functions into a single construction machine platform. The main body device can perform excavation, the conveyance device can transport materials, and the processing device can sort and process excavated materials. This multi-functional integration allows the machine to adapt to various construction tasks without requiring separate specialized equipment for each function.
Solution Approach 2:
The patent combines excavation, conveyance, and processing functions into one integrated machine system. The working device, conveyance device, and processing device are merged into a coordinated system where materials flow continuously from excavation through conveyance to processing, creating a unified multifunctional construction machine.
