Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a blister bracket with soft material is used to control costs, then manufacturing cost is reduced, but installation position accuracy deteriorates due to excessive flexibility
Solution Approach 1:
The CCS bracket is divided into two distinct parts: a first bracket for mounting electrical components and a second bracket for positioning relative to the battery cell. This segmentation allows each part to be optimized independently - the first bracket can remain flexible and cost-effective while the second bracket provides the necessary positioning rigidity through its positioning structure.
Solution Approach 2:
The positioning structure is locally added to the second bracket at the specific location where positioning is needed. This localized enhancement provides the necessary rigidity and positioning accuracy only where required, while the rest of the bracket structure maintains its cost-effective design. The positioning structure includes features such as positioning holes or positioning grooves that engage with corresponding features on the battery cell.
2Quantity of substance
If a soft material bracket is used, then material cost is reduced, but positioning strength and rigidity deteriorate
Solution Approach 1:
By separating the bracket into two parts, the positioning function is isolated to the second bracket. This allows the positioning structure to be designed with appropriate strength characteristics without requiring the entire bracket to be made from expensive, high-strength material. The first bracket can use softer, cheaper material while the second bracket provides the necessary positioning strength.
Solution Approach 2:
The positioning structure on the second bracket is designed with local quality enhancement - adding rigidity and strength specifically at the positioning features (positioning holes, positioning grooves, or bump structures) while maintaining cost-effective material usage in non-critical areas. This localized strengthening provides the necessary positioning strength without proportionally increasing overall material cost.
3Quantity of substance
If a soft material bracket is used, then material cost is reduced, but positioning rigidity deteriorates
Solution Approach 1:
The functional segmentation allows the second bracket to be designed specifically for positioning stability. The positioning structure on the second bracket incorporates features that enhance rigidity in the critical positioning direction, while the first bracket maintains its cost-effective, more flexible design for mounting electrical components.
Solution Approach 2:
The positioning structure introduces local quality changes to enhance rigidity where needed. Features such as reinforced positioning holes, positioning grooves with appropriate geometry, or bump structures provide localized rigidity enhancement at the positioning interface, while the rest of the bracket structure maintains cost-effective material usage.

AI summary
The present disclosure provides a CCS bracket (001), a CCS assembly (003), and a battery module, and relates to the technical field of batteries. The CCS bracket (001) includes a first bracket (Oil) and a second bracket (012). The first bracket (011) is configured to install electrical components of the CCS assembly (003). The second bracket (012) is connected to the first bracket (011) and provided with a positioning structure for positioning the first bracket (Oil) relative to a battery cell (002). In the present disclosure, a strength and a rigidity of a positioning and matching part of the CCS bracket (001) relative to the battery cell (002) is increased, thereby facilitating the positioning of the CCS bracket (001) relative to the battery cell (002) and ultimately improving an installation position accuracy of the CCS assembly (003).
