ECU Connector Pressure Equalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic control units require a separate air pressure correcting device, which increases assembly space, time, and manufacturing costs due to its independent configuration.
Innovation Solution
Incorporating a pressure correcting means directly into the connector of the electronic control unit, featuring a venting hole, venting channel, and air-permeable separating membrane, which adjusts internal pressure by communicating with the exterior through a venting hole and channel, and is protected by a venting hole protecting plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate air pressure correcting device is used, then pressure correction function is achieved, but assembly space, time, and manufacturing costs increase
Solution Approach 1:
The pressure correction function is merged with the connector by integrating a venting hole and venting channel directly into the connector structure. This eliminates the need for a separate air pressure correcting device, thereby reducing assembly space, time, and manufacturing costs while maintaining the pressure correction function.
Solution Approach 2:
The connector is designed to serve multiple functions: electrical connection and pressure correction. By incorporating the venting hole and venting channel into the connector, it becomes a multi-functional component that both transmits electrical signals and regulates pressure between the housing interior and exterior.
2Reliability
If a separate air pressure correcting device is mounted to the housing, then pressure correction is achieved, but assembly space and manufacturing costs increase
Solution Approach 1:
The pressure correction functionality is combined with the connector manufacturing process. The venting hole and venting channel are formed as integral parts of the connector, allowing both components to be manufactured together, thereby reducing manufacturing costs and simplifying production.
3Reliability
If the venting hole is exposed to the outside, then pressure correction function works, but the venting hole is vulnerable to external damage
Solution Approach 1:
A vehicle side connector is introduced as an intermediary component that covers and protects the venting hole of the ECU connector. This protective structure allows the venting hole to remain functional for pressure correction while shielding it from external damage, dirt, and moisture.
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 integrated solution reduces assembly time and costs by eliminating the need for a separate pressure correcting device, while maintaining stable pressure for signal transmission and protecting the components from external damage.
Implementation Method 1
a venting channel which allows the venting hole and the interior of the housing to communicate with each other
Implementation Method 2
An air-permeable separating membrane may be provided in the venting hole or on a surface of the connector in which the venting hole is formed
