Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs face challenges in accurately measuring temperature due to inconsistent placement of temperature sensors, leading to unreliable temperature readings and safety concerns.
Innovation Solution
A battery pack design featuring a module case with a recessed receiving portion and a holder that securely fixes a temperature sensor, utilizing an elastic material to maintain consistent contact with battery cells, and includes a fixing rib to guide the holder's position, ensuring uniform distance and reliable temperature measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the temperature sensor is directly inserted into the receiving space of the module case with hands, then the installation process is simple, but the insertion location is subjected to change and the position cannot be kept constant
Solution Approach 1:
The patent introduces a holder as an intermediary component between the module case and the temperature sensor. The holder includes a receiving groove that precisely positions the temperature sensor, and this holder is then installed into the module case. This intermediary structure eliminates the need for direct manual insertion of the sensor into the case, ensuring consistent positioning while maintaining ease of installation through the pre-fitted holder structure.
2Ease of manufacture
If only adhesive is used to fix the temperature sensor, then the fixing process is simple, but the position of the temperature sensor is easily changed by external impacts before the adhesive is cured
Solution Approach 1:
The patent implements preliminary positioning through the holder structure before the adhesive curing process. The holder's receiving groove pre-establishes the correct position of the temperature sensor, and the holder itself is fixed to the module case with adhesive. This preliminary mechanical positioning ensures that even before the adhesive fully cures, the sensor cannot be easily displaced by external impacts, as it is constrained within the holder's groove structure.
3Adaptability or versatility
If the temperature sensor position varies, then manufacturing is more flexible, but the temperature measurement reliability decreases and safety management becomes difficult
Solution Approach 1:
The holder acts as a mediating structure that decouples the positioning function from the installation process. By incorporating a precisely dimensioned receiving groove in the holder, the system ensures that the temperature sensor always occupies the same optimal position relative to the battery cells, regardless of manufacturing variations. This maintains measurement precision while allowing flexible installation through the standardized holder interface.
