Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Driving robots require significant effort to adapt the maximum travel of actuators to different pedal configurations, as the distance between the neutral and depressed pedal positions varies with the vehicle, necessitating time-consuming teaching processes and complex measurement technologies.
Innovation Solution
An actuating device with a rotationally symmetrical actuating rod and electromagnetic force-generating means, allowing the actuating rod to be easily connected and positioned by manually guiding it to the pedal with minimal force, eliminating the need for force-measuring sensors and simplifying the setup and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If force measurement sensors are attached to the actuators to continuously determine the actuating force, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent replaces mechanical force measurement sensors with an electromagnetic actuating rod that directly generates and measures force through electromagnetic interaction. The force is determined by measuring electrical parameters (current, voltage, impedance) of the electromagnetic system rather than using separate mechanical sensors, thereby eliminating complex measurement and evaluation technology while maintaining measurement capability.
Solution Approach 2:
The electromagnetic actuating rod serves dual functions: it actuates the pedal and simultaneously measures the actuating force through its own electrical characteristics. The system uses itself for measurement rather than requiring external sensing equipment, reducing device complexity while maintaining measurement precision.
2Adaptability or versatility
If the actuator is taught its maximum travel path step by step during test cycle setup, then adaptability to different pedal configurations is achieved, but loss of time during setup and teaching increases
Solution Approach 1:
The patent incorporates a path measurement device that pre-determines the neutral position and maximum travel path of the pedal before the test cycle begins. This preliminary measurement eliminates the need for time-consuming step-by-step teaching during setup, as the actuator is pre-configured with the correct travel parameters for the specific pedal configuration.
Solution Approach 2:
The patent replaces the mechanical step-by-step teaching process with an automated optical or electronic path measurement system. The measurement device uses light or electronic signals to quickly determine pedal positions and travel paths, substituting slow manual adjustment with fast automated measurement, thereby reducing setup time while maintaining adaptability.
3Ease of operation
If electromagnetic force-generating means are used to move the actuating rod, then ease of operation and setup is improved, but device complexity increases due to electromagnetic components
Solution Approach 1:
The electromagnetic actuating rod serves multiple functions: it actuates the pedal, measures the actuating force through electrical parameters, and enables easy positioning through electromagnetic control. By combining these functions in a single component, the patent avoids adding separate mechanisms for each function, thereby improving ease of operation without proportionally increasing device complexity.
