Solution Overview
Problem
Conventional machines with internal combustion engines require complex systems for fuel conversion, emissions control, and energy storage, limiting efficiency and increasing emissions, and existing hybrid solutions still rely on internal combustion engines with associated components.
Innovation Solution
A machine control system and configuration enabling the use of interchangeable power sources, such as internal combustion engines, batteries, or fuel cells, with a power system electronic control module that standardizes power output and controls machine operations regardless of the power source, eliminating the need for traditional engine-related components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If an internal combustion engine is used as the power source, then the machine can operate with high power output, but the machine requires complex fuel supply systems, exhaust aftertreatment systems, and cooling systems
Solution Approach 1:
The machine is designed with a universal power system architecture that can accommodate multiple power source types (internal combustion engines, electric motors, fuel cells) through a common control system and standardized interface. The electronic control module can detect and adapt to different power source characteristics, allowing the same machine platform to utilize various power sources without requiring dedicated complex systems for each type.
2Power
If an internal combustion engine is used to meet power requirements, then the machine achieves desired performance, but emissions and energy loss increase
Solution Approach 1:
The system enables dynamic switching between different power sources based on operational requirements and environmental conditions. By changing the power source parameter from always using internal combustion to selectively using electric or fuel cell power, the system maintains power performance while reducing emissions during appropriate operating conditions.
3Reliability
If the machine is designed for a specific power source, then the control system can be optimized for that power source, but the machine cannot accommodate alternative power sources
Solution Approach 1:
The control system is designed to dynamically detect the type of power source installed and automatically adjust its operation mode accordingly. The electronic control module can identify whether an internal combustion engine, electric motor, or fuel cell is present and optimize control parameters in real-time, enabling both control optimization and power source versatility through adaptive dynamics.
4Duration of action of moving object
If fuel storage and fuel injection systems are included, then the machine can operate with internal combustion engines, but the machine weight and complexity increase
Solution Approach 1:
The system design allows for the extraction and removal of fuel storage and fuel injection systems when alternative power sources are used. By making these components optional rather than mandatory, the machine can operate without them when using electric or fuel cell power sources, thereby reducing weight while maintaining operational capability through different means.

AI summary
A machine control system controls operation of any one of a plurality of interchangeable power sources mounted on a machine. The machine includes an undercarriage supporting ground engagement members that propel the machine and an upper structure rotatably supported on the undercarriage. The upper structure includes a swing frame that supports an operator cab, an interchangeable power source, hydraulic components, and electrical components. A processor processes inputs, outputs and operating characteristics specific to each of the plurality of power sources, and standardizes the power output by each of the power sources to provide a normalized, consistent control and operation of systems of the machine regardless of which of the power sources is mounted on the machine.
