Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If accelerator and braking pedals are arranged side by side for flexible control, then ease of operation is improved, but the risk of erroneous acceleration increases
Solution Approach 1:
A robotic arm is introduced as an intermediary mechanism between the accelerator pedal and the engine control system. The robotic arm detects excessive accelerator depression through pressure sensors and transmits correction signals to the control system, thereby mediating between the driver's input and the vehicle's acceleration response to prevent erroneous acceleration
Solution Approach 2:
The system implements feedback by using pressure sensors to detect the degree of accelerator depression, comparing it against safe thresholds, and automatically sending correction signals to reduce or cancel acceleration when excessive depression is detected, creating a closed-loop control system that monitors and corrects accelerator input
2Reliability
If driver training is strengthened to reduce erroneous acceleration, then safety is improved, but the complexity of training and assessment increases
Solution Approach 1:
The vehicle system performs self-service by automatically detecting and correcting erroneous acceleration without requiring driver training or intervention. The robotic arm and pressure sensor system autonomously monitors accelerator input and implements correction, replacing the need for complex driver education and assessment programs
3Reliability
If automatic correction system is added to prevent erroneous acceleration, then safety is improved, but device complexity increases
Solution Approach 1:
The robotic arm is designed with multi-functionality, serving both as a structural support element and as an active sensor mounting platform for detecting accelerator depression. This universal design integrates multiple functions into a single component, reducing overall system complexity while maintaining safety functionality

Implementation Method 1
An elastic damper having a signal switch is arranged on a side wall of the error correction control box directly facing the robotic arm. The accelerator pedal enables the robotic arm to abut against the elastic damper. When excessive depression is applied, the elastic damper is compressed and deformed by the robotic arm and triggers the signal switch.

AI summary
The present disclosure discloses an automatic correction device for erroneous acceleration of an automobile, which includes an accelerator pedal, a robotic arm, and an acceleration sensor. The acceleration sensor is connected to a central control computer of the automobile. An error correction control box is arranged on a front cab baffle in front of the robotic arm. An elastic damper having a signal switch is arranged on a side wall of the error correction control box directly facing the robotic arm. The accelerator pedal enables the robotic arm abuts against the elastic damper. When excessive depression is applied, the elastic damper is compressed and deformed by the robotic arm and triggers the signal switch. After the signal switch is triggered, a clear warning sound or a humming sound is sent to prompt a driver to stop the excessive depression.
