## 4 Research Findings  
Based on the results of the calculation of the positive ideal solution, negative ideal solution, and relative closeness of each scheme (Table 11), Scheme 1 had the highest relative closeness ranking and was therefore rated as the best packaging design scheme for clay figurines. As an evaluation sample of the existing solutions in the market, they were all \begin{table}

This indicates that the novel Stingray model is highly feasible for non-heritage packaging design. In this study, the main findings of sustainable design and assessment of non-heritage packaging of clay molding in Joon County based on the novel Stingray model are as follows:  
(1) Multi-method integrated modeling significantly improves design science and feasibility  
The new Stingray model, constructed by integrating perceptual engineering, AHP hierarchical analysis, and TOPSIS, effectively solves the two bottlenecks of \"insufficient quantification of perceptual needs\" and \"lack of sustainability assessment\" in the application of generative tools. The perceptual engineering method extracts 12 core perceptual words from modeling, function, and other dimensions, such as \"innovative\" and \"sustainable\", and after AHP weighting analysis (criterion weighting: modeling 0.538 > function 0.301 > material 0.112 > color 0.048), it is clear that the modeling is not enough to quantify the perceptual needs and the lack of sustainability assessment in the application of generative tools. (color 0.048), the design priorities of \"innovative\", \"safe\", \"sustainable\", and \"interesting\" were clearly defined, which significantly reduced the number of design priorities, and the number of design priorities was reduced to \"innovative\", \"safe\", \"sustainable\", and \"interesting\". The TOPSIS evaluation results show that the relative closeness (Ci = 0.785) of this study's scheme (Scheme 1) is significantly higher than that of the existing schemes in the market (Scheme 2, Ci = 0.503, and Scheme 3, Ci = 0.299), which verifies the validity of the model in balancing the goals of cultural expression and sustainability. (2) Generative tools and the scientific method synergistically drive efficiency optimization  
Multiple control groups were set up, one using the traditional design method and the other using the generative design method, and the time to generate multiple design items was tracked separately to obtain the average generation time. It was calculated that the cycle time for generating NRL packaging patterns using generative tools saves at least 35% of the time compared to the traditional design time. (3) Enhanced Environmental Benefits from Sustainable Materials and Structural Innovations  
Based on the advantage that Henan accounts for 28% of the country's wheat cultivation area and is rich in straw resources, the use of a thermal compression molding process reduces the carbon footprint of packaging shells by 67% compared to traditional plastics and shortens the degradation cycle from 500 years to 6 months [70]. According to user surveys, the \"natural texture\" and \"cultural affinity\" of straw materials increased consumer satisfaction, confirming the market potential of bio-based materials in non-heritage packaging.
