Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a remote control device is dedicated to a specific machine type with fixed hardware circuits, then the control reliability for that specific machine is ensured, but the adaptability to different machine types is lost and hardware modification costs increase

Engineering Contradiction:
Improvecontrol reliabilityVSAvoidadaptability to different machine types
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The remote control device is designed with a universal processor-based architecture that can control multiple types of work equipment (excavators, loaders, forklifts, etc.) through software configuration rather than dedicated hardware circuits. The processing unit executes control programs that can be adapted to different machine types, eliminating the need for hardware modifications while maintaining reliable control for each specific machine type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces traditional analog hardware circuits with a digital processing unit that uses software programs to implement control logic. This substitution allows the same physical hardware to be reconfigured for different machine types through software updates, providing both reliability through standardized hardware and adaptability through programmable control logic.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the remote control hardware is modified to support a different operating concept, then the versatility of the remote control device is improved, but the manufacturing complexity and costs increase significantly

Engineering Contradiction:
Improveversatility of remote control deviceVSAvoidhardware modification complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The remote control device employs dynamic software configuration instead of static hardware design. The processing unit can load and execute different control programs corresponding to various operating concepts and machine types, allowing the device to adapt its functionality dynamically without any physical hardware changes. This reduces manufacturing complexity while maintaining high versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the control parameters and software configuration rather than hardware parameters when adapting to different machine types. By modifying software settings, control algorithms, and interface configurations, the same hardware platform can support multiple operating concepts, avoiding the complexity and costs of hardware reengineering.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If each machine type has its own dedicated remote control, then the ease of operation for that specific machine is optimized, but the loss of time for operators to manage multiple remote controls increases

Engineering Contradiction:
Improveease of operation for specific machineVSAvoidtime to manage multiple remote controls
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

A single universal remote control device can operate multiple types of work equipment by loading appropriate control programs. Operators only need to manage one remote control unit, switching between machine types through software selection rather than physically handling multiple dedicated remote controls, thereby reducing time loss while maintaining machine-specific operational optimization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges multiple dedicated remote control functions into a single universal device. By combining the control capabilities for excavators, loaders, forklifts, and other equipment into one integrated system with programmable functionality, operators consolidate their toolset and reduce the time spent managing multiple separate remote controls.

Inventive Principle:
Principle #5Merging (Combining)
