Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel injection systems face misalignment issues due to manufacturing tolerances and maintenance-related factors, leading to suboptimal performance and the need for expensive electronic adjustments that are not readily accessible to small mechanics or DIY users.
Innovation Solution
A programmable dongle connected via the OBD-II port that automatically adjusts the throttle body position to manufacturer-specified settings, using multiple communication protocols and sensors to ensure accurate and efficient calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment methods are used for throttle body alignment, then device complexity is reduced, but measurement precision and manufacturing precision deteriorate
Solution Approach 1:
The patent replaces manual mechanical adjustment methods with an electronic control system that uses a programming dongle to communicate with the ECU. The ECU automatically adjusts the throttle valve position through electronic signals, eliminating the need for manual mechanical alignment while achieving precise positioning according to manufacturer specifications.
Solution Approach 2:
The system enables self-service programming where the technician uses a simple dongle device to initiate the programming sequence. The ECU then autonomously performs the throttle body alignment by automatically adjusting the throttle valve position based on feedback from the TPS, without requiring manual intervention or specialized equipment.
2Manufacturing precision
If expensive electronic adjustment devices are used, then manufacturing precision improves, but ease of operation and accessibility deteriorate
Solution Approach 1:
The patent employs a low-cost, simple programming dongle device that interfaces with the vehicle's OBD-II port. This inexpensive tool provides the same alignment precision as expensive electronic systems, making the service accessible to small shops and DIY mechanics without requiring investment in costly specialized equipment.
Solution Approach 2:
The programming dongle serves as an intermediary device that bridges the gap between the technician and the vehicle's ECU. It translates simple user actions into the complex electronic communication protocols required for throttle body programming, simplifying the operation while maintaining precision.
3Ease of operation
If manufacturer preferred operating ranges are not considered, then ease of operation improves, but reliability and performance deteriorate
Solution Approach 1:
The system incorporates feedback mechanisms where the ECU continuously monitors the throttle valve position via the TPS and compares it against manufacturer-specified target ranges. The ECU automatically makes adjustments until the throttle body alignment falls within the optimal operating parameters, ensuring both simplicity and reliability.
Solution Approach 2:
The programming process pre-loads the manufacturer's preferred operating ranges and target throttle valve positions into the ECU before the adjustment begins. This allows the system to automatically guide the adjustment process toward the optimal settings without requiring the technician to manually input or understand these complex parameters.
Data Source
AI summary
A dongle for setting the position of a throttle plate in a throttle body has a process that is driven by a power supply regulated to 5 Vdc to generates a graphic representation of an acceptable range for engine revolutions per minute and throttle plate position within a throttle body. A comparator extracted information from an interrogation of the engine control monitor to determine if the throttle body is within the acceptable range. A signal is generated to indicates the presence or absence of an acceptable range.
