Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic arrangements for motor vehicle transmissions face challenges with soldering processes at high temperatures, which can damage sensor domes and obstruct assembly processes, and require early soldering that complicates the assembly of long sensor domes.
Innovation Solution
The implementation of a plug-in connection between dome contacts and circuit contacts eliminates the need for soldering, allowing for a flexible and robust electrical connection that can be made without the equipment and heat associated with soldering, and allows for later installation of sensor domes, enabling multiple connections and improved resistance to media in the transmission compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldering is used to connect circuit contacts to dome contacts, then electrical connection reliability is improved, but the sensor dome functionality and dimensional tolerance are adversely affected due to high temperatures
Solution Approach 1:
The invention separates the electrical connection process from the sensor dome assembly process. The circuit contacts are pre-assembled on the control circuit board, and the sensor dome is attached separately to the sensor housing, avoiding direct exposure to soldering heat. This segmentation allows each component to be manufactured and assembled independently without thermal interference.
Solution Approach 2:
The patent introduces an intermediary approach by using pre-assembled circuit contacts that can be connected to the sensor dome through a controlled interface. The sensor dome is mounted on the sensor housing after the control circuit is assembled, acting as an intermediary step that prevents direct thermal exposure during soldering.
2Reliability
If soldering is used to connect contacts, then electrical connection is achieved, but the assembly process is obstructed and requires early timing that complicates production
Solution Approach 1:
The circuit contacts are pre-assembled and soldered to the control circuit board before the sensor dome is attached. This preliminary action allows the electrical connection to be established in advance, and the sensor dome can be added later in the assembly process without requiring re-soldering or complex coordination, thereby improving overall production efficiency.
3Reliability
If high temperatures are applied during soldering, then electrical connection is secured, but the sensor functionality is adversely affected
Solution Approach 1:
The invention divides the assembly into two separate stages: first, the control circuit with circuit contacts is assembled and soldered; second, the sensor dome is attached to the sensor housing. This segmentation ensures that the sensor dome never暴露 to soldering temperatures, protecting its functionality while still achieving secure electrical connections through the circuit contacts.
