## 3 Parametric Design Practice
### Parametrically Adjusted Battery Pack  
Within the complex framework of parametric design, parametrically adjustable battery packs play a crucial role, serving not only as a bridge between designers and computer algorithms but also as the key to seamlessly integrating creative precision with technical implementation. Leveraging Grasshopper, an excellent parametric design platform, we have developed a highly integrated, flexible, and real-time feedback parametric adjustable battery pack, aiming to drive the infinite possibilities of ceramic product shaping through precise parameter control.  
According to the logical flow of parametric design, the battery pack is divided into multiple levels, including the basic parameter input layer, computational processing layer, shape generation layer, and feedback optimization layer. Each level bears specific functions, progressively deepening to form a closed design cycle process. Within the battery pack, we have established logical chains between parameters to ensure that any adjustment is accurately transmitted to every stage of shape generation. Through advanced programming techniques such as conditional judgment and iterative loops, we have achieved mutual dependence and constraints between parameters, enhancing the flexibility and controllability of the design. For key parameters (such as curve radius, angle, height, number of segments), we have specifically designed input components that support various input methods, including numerical input, slider drag, and preset value selection, aiming to meet diverse design requirements. Leveraging Grasshopper's instant update mechanism, we have achieved real-time dynamic parameter adjustments. Whenever a parameter changes, the battery pack immediately recalculates and updates the shape, ensuring designers can see the adjustment effects in real-time, thus achieving more precise personalized choices.  
This article integrates Rhino's 3D view function to display the parametrically generated ceramic product shapes in real-time for designers. This intuitive visual feedback significantly improves design efficiency, enabling designers to rapidly iterate and optimize their design solutions. In addition to real-time visual previews, we have introduced a performance evaluation module to assess the structural strength, material consumption, and other aspects of the generated shapes. The evaluation module is concerned with aspects such as structural strength and material consumption. The 3D model generated by the modeling software Rhino is imported into the slicing software. In the software, the structural strength and material consumption will be automatically displayed. It provides designers with intuitive feedback on the assessment results. This data-driven feedback mechanism helps designers find the optimal balance between creativity and practicality. We have optimized the battery pack algorithm, effectively reducing redundant calculations and, thus, enhancing overall operational efficiency. At the same time, we have modularized the battery pack for easier maintenance and upgrades in the future. To meet the future expansion needs of parametric design, we have meticulously designed multiple expansion interfaces for the battery pack. This means that designers can easily add new parameters, computational components, or shape generation methods according to actual needs, continuously expanding the boundaries of parametric design (see Figure 6).  
In summary, the parametric adjustment battery pack we built not only realizes the fine control and dynamic adjustment of ceramic product shape, but also provides designers with an efficient, flexible, and easy-to-iterate parametric design environment through the real-time preview and feedback mechanism, performance optimization, and scalability considerations and other design details.
