Integrated EV Pedestrian Alert Pedal Layout for Compact Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pedestrian alert devices for electric vehicles have a complex and costly structure due to separately arranged sound producing, control, and accelerator pedal mechanisms, leading to inefficient data transmission and high costs.
Innovation Solution
A compact pedestrian alert device integrating the controller with the accelerator pedal mechanism and sound producing mechanism, where the controller is electrically connected to both, facilitating efficient data transmission and reducing costs by housing the controller within the accelerator pedal mechanism's installation box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the controller, sound producing mechanism, and accelerator pedal mechanism are separately arranged in different portions of the vehicle, then each component can be independently designed and maintained, but the data transmission process becomes complicated, cost increases, and the structure is not compact
Solution Approach 1:
The controller is integrated into the accelerator pedal mechanism assembly, merging previously separate components. The controller is disposed within the installation box that houses the accelerator pedal mechanism, eliminating the need for separate mounting locations and reducing data transmission complexity between distant components.
2Reliability
If the controller and accelerator pedal mechanism are far apart and independently arranged, then component failure isolation is improved, but data transmission efficiency decreases and cost increases
Solution Approach 1:
The controller is disposed within the installation box of the accelerator pedal mechanism, placing them in close proximity. This integration improves data transmission efficiency while maintaining functional independence for failure isolation.
3Ease of manufacture
If separate arrangement of components is used, then modular assembly is simplified, but overall device compactness deteriorates
Solution Approach 1:
The controller is housed within the installation box that already contains the accelerator pedal mechanism, utilizing existing space rather than adding separate mounting locations. This integration improves device compactness while maintaining modular assembly benefits.
