Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current construction machines that aim to reduce greenhouse gas emissions lack effective methods for mounting fuel cells and often have limited layout flexibility due to the presence of a driver's seat in automatic operation systems.
Innovation Solution
A construction machine design featuring a main body unit that can revolve, equipped with a hydrogen tank and a fuel cell system, allowing for unmanned operation and high layout flexibility through the use of drones and a modular design that includes multiple revolving parts, enabling efficient excavation and loading operations while minimizing greenhouse gas emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a driver's seat is provided in automatic operation, then operation safety is improved, but layout flexibility is limited
Solution Approach 1:
The driver's seat is completely removed from the construction machine. Instead of providing a driver's seat in automatic operation, the patent extracts the operator from the physical workspace and replaces them with an unmanned automated system, thereby eliminating the space occupation and layout constraints that a driver's seat would impose while maintaining operational safety through automation.
Solution Approach 2:
The construction machine is equipped with automatic operation capabilities that enable it to perform excavation and loading tasks autonomously without human intervention. The machine serves itself by incorporating sensors, control systems, and automated mechanisms that allow it to complete work cycles independently, removing the need for a driver's seat entirely.
2Object-generated harmful factors
If a fuel cell is installed in the construction machine, then greenhouse gas emissions are reduced, but device complexity increases
Solution Approach 1:
The powertrain system is segmented into distinct functional modules: a hydrogen tank for fuel storage, a fuel cell for electricity generation, and a motor for mechanical work. This modular segmentation allows each component to be optimized independently and simplifies the overall system architecture, making the zero-emission powertrain more manageable despite the added complexity of alternative fuel systems.
