Combined Accelerator Brake Pedal with Resisting Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traffic accidents often occur due to drivers instinctively stepping on the accelerator pedal during emergencies, as the separate positioning of accelerator and brake pedals can lead to confusion and incorrect foot placement.
Innovation Solution
A combined accelerator and brake pedal device featuring a connecting lever, brake pedal assembly, accelerator pedal assembly, accelerator control circuit, and resisting member, where the accelerator control circuit is rendered inoperative when the resisting member is moved by the accelerator pedal assembly toward the accelerator control switch, preventing accidental acceleration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate accelerator and brake pedals are positioned in the vehicle, then the driver can operate them independently, but the driver may instinctively step on the accelerator pedal during emergencies causing traffic accidents
Solution Approach 1:
The patent combines the accelerator pedal assembly and brake pedal assembly into a single integrated pedal structure. The accelerator pedal assembly is rotatably coupled to the brake pedal assembly, allowing both functions to share a common pedal body while maintaining independent operational capability through the connecting lever mechanism.
Solution Approach 2:
The connecting lever acts as an intermediary mechanism between the accelerator pedal assembly and brake pedal assembly. It transmits and differentiates the driving forces applied to different portions of the combined pedal, enabling the system to distinguish between accelerator inputs and brake inputs despite the unified structure.
2Reliability
If the accelerator control circuit remains operative during brake pedal operation, then the accelerator system remains responsive, but unintended acceleration may occur during emergency braking
Solution Approach 1:
The resisting member is pre-positioned to contact the accelerator control switch and prevent it from activating. When the brake pedal assembly is depressed, the connecting lever moves the resisting member to maintain contact with the switch, proactively preventing any possibility of accelerator signal activation during brake operation.
Solution Approach 2:
The patent extracts the accelerator control function from the combined pedal operation by using the resisting member to physically isolate the accelerator control switch from activation during brake pedal use. This separation ensures that brake inputs cannot inadvertently trigger the accelerator control circuit.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures that the accelerator control circuit is only operative when the brake pedal is released, thereby preventing unintended acceleration and reducing the likelihood of traffic accidents during emergency situations.
Implementation Method 1
an elastic member, the other end of which is resisted to the brake pedal assembly
Implementation Method 2
The resisting member can be positioned on the connecting lever away from the brake pedal assembly. The accelerator control switch can be resisted to turn off by the resisting member
