Battery Pack Temperature Sensor Direct PCB Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs face complex assembly processes due to the need for connecting temperature sensors to printed circuit boards using wires or other elements, which increases the time and effort required for assembly.
Innovation Solution
The temperature sensor is directly mounted on the printed circuit board, eliminating the need for additional connecting elements by forming a carrier element that is part of the circuit board, allowing for a more straightforward and efficient assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature sensor is connected to printed circuit board using wires or connecting elements, then reliable temperature measurement is achieved, but assembly complexity and assembly time increase
Solution Approach 1:
The patent integrates the temperature sensor directly onto the printed circuit board by forming a carrier element that is part of the circuit board itself. This merging of the sensor mounting function into the PCB structure eliminates the need for separate connecting elements and wires, thereby reducing assembly complexity while maintaining reliable temperature measurement capability.
2Productivity
If temperature sensor is directly mounted on printed circuit board, then assembly time and complexity are reduced, but measurement precision may be affected by direct contact requirements
Solution Approach 1:
The patent introduces a carrier element as an intermediary component that is formed as part of the printed circuit board. This carrier element serves as a mounting platform for the temperature sensor, enabling direct mounting on the PCB while providing a controlled interface that ensures proper thermal contact with the battery cell. The carrier element acts as a mediator that facilitates both easy assembly and accurate temperature measurement.
3Stability of the object's composition
If separate fastening elements are used to attach temperature sensor, then secure mounting is achieved, but manufacturing cost and assembly steps increase
Solution Approach 1:
The patent combines the fastening function into the printed circuit board by forming the carrier element as an integral part of the PCB structure. This eliminates the need for separate fastening elements and reduces the number of assembly steps. The carrier element provides stable mounting for the temperature sensor through its integrated design, thereby achieving secure mounting while improving ease of manufacture.
