Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-gear mechanical throttle knob is used, then the throttle can be adjusted through multiple gears, but gear-skipping occurs due to fatigue life reduction of mechanical gears, leading to poor control stability
Solution Approach 1:
The patent replaces the mechanical multi-gear throttle knob with an electronic throttle control system. The electronic throttle control apparatus uses an electronic throttle position sensor to detect throttle position and a microcontroller to control throttle opening, eliminating mechanical gears entirely. This substitution resolves the gear-skipping issue by replacing the unreliable mechanical transmission system with an electronic control system that provides stable and precise throttle positioning without mechanical wear or skipping.
2Adaptability or versatility
If a conventional electrical system is used, then the system structure is simple, but it cannot meet diverse needs for intelligent operations
Solution Approach 1:
The patent implements a multi-functional integrated control system where the electronic throttle control apparatus serves multiple purposes: basic throttle control, intelligent operation modes (single-hand operation, remote control), data monitoring (throttle position, engine parameters), and adaptive control based on operational conditions. The microcontroller integrates multiple control functions and the system can adapt to different operational needs through software configuration, providing universal intelligence across various excavation scenarios without requiring separate specialized systems.
Solution Approach 2:
The patent introduces a remote control device as an intermediary between the operator and the excavator throttle control. The remote control transmits control signals wirelessly to the microcontroller, enabling remote operation capability. This intermediary component adds intelligent control versatility without significantly complicating the core throttle control system, as it interfaces through the existing electronic control architecture.
3Ease of manufacture
If a mechanical gear-based throttle knob is used, then the structure is traditional and simple to manufacture, but it lacks flexible configuration according to diverse operational needs
Solution Approach 1:
The patent implements a dynamic and reconfigurable electronic throttle control system where operational parameters, control modes, and response characteristics can be adjusted through software configuration rather than physical reconfiguration. The microcontroller allows for programmable control logic that can adapt to different operational needs, enabling flexible configuration of throttle response curves, operational modes, and control parameters without manufacturing changes. This dynamic software-based configuration provides adaptability while maintaining manufacturing simplicity through standardized electronic components.

AI summary
The invention discloses an excavator throttle control device and method. The device comprises a main controller (1), an engine control module (ECM) (2), an electronic monitor (3), a starting unit (4), a power supply relay (5) and an integrated switch panel (6). The integrated switch panel (6) effectively integrates a power switch and a throttle knob, and is used to control a throttle gear through operational switches and transmit a control instruction to the main controller (1). The main controller (1) is used to determine an engine speed according to the gear control instruction sent by the integrated switch panel (6) and send the same to the ECM (2). The ECM is used to control an engine to execute a corresponding speed for a specific gear. The invention utilizes intelligent throttle control and a composite key function to achieve switching between throttle increase and decrease modes, as well as quick throttle control, enhancing the level of intelligence. The use of a resettable increase/decrease knob gear minimizes reliability issues caused by multiple gears and improves operability.
