Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive liquid is used to reinforce rigidity and enhance cooling functions, then structural strength and cooling performance are improved, but assembly difficulty increases due to adhesive resistance
Solution Approach 1:
The cell support is divided into multiple functional regions: through-holes for adhesive injection, guide grooves for adhesive flow control, and support portions for cell positioning. This segmentation allows the adhesive to be applied in a controlled manner, reducing resistance during assembly while ensuring adequate structural reinforcement.
Solution Approach 2:
The guide groove acts as an intermediary structure that facilitates the flow of adhesive liquid from the through-hole to the bonding interface. By providing a dedicated flow path, the guide groove reduces the resistance that would otherwise occur during adhesive application and cell assembly.
2Temperature
If adhesive liquid is used to enhance cooling functions, then thermal management performance is improved, but assembly difficulty increases due to adhesive resistance
Solution Approach 1:
The cell support is divided into multiple functional regions: through-holes for adhesive injection, guide grooves for adhesive flow control, and support portions for cell positioning. This segmentation allows the adhesive to be applied in a controlled manner, reducing resistance during assembly while ensuring adequate structural reinforcement.
Solution Approach 2:
The guide groove acts as an intermediary structure that facilitates the flow of adhesive liquid from the through-hole to the bonding interface. By providing a dedicated flow path, the guide groove reduces the resistance that would otherwise occur during adhesive application and cell assembly.
3Reliability
If adhesive liquid is applied to ensure dense and tight fill, then structural integrity and cooling efficiency are improved, but assembly resistance increases
Solution Approach 1:
The guide groove is pre-formed on the cell support to create a flow path for the adhesive liquid. This preliminary structural preparation ensures that when adhesive is applied during assembly, it naturally flows along the guide groove to achieve dense and tight fill without creating excessive resistance, thereby maintaining both reliability and ease of assembly.
4Ease of manufacture
If through-holes are provided for adhesive injection, then adhesive application is facilitated, but structural complexity increases
Solution Approach 1:
The cell support is divided into multiple functional regions: through-holes for adhesive injection, guide grooves for adhesive flow control, and support portions for cell positioning. This segmentation allows the adhesive to be applied in a controlled manner, reducing resistance during assembly while ensuring adequate structural reinforcement.
Solution Approach 2:
The cell support structure integrates multiple functions into a single component: it provides mechanical support for battery cells, serves as a substrate for adhesive application through through-holes, guides adhesive flow via grooves, and enhances cooling. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in structural complexity.

AI summary
The present disclosure is directed to providing a battery cell holder capable of further reducing the resistance of an adhesive liquid when a battery cell is assembled to a structure of a lower side of a battery. The battery cell holder includes a cell support in which a plurality of battery cells are fitted and seated, a through-hole formed through the cell support and into which an adhesive liquid is introduced, and a guide groove formed on the cell support to extend in a seated direction of the battery cell, coming into contact with the through-hole and configured to form a passage through which the adhesive liquid can flow along a side surface of the battery cell.
