Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If particle system is used to simulate firework visual effects, then visual effects such as fire, explosion, smoke can be simulated, but the firework visual effect lacks realism

Engineering Contradiction:

Improverealism of firework visual effectVSAvoidcomplexity of particle system implementation

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The firework visual effect is segmented into multiple particle sets with different functions: firework particles for the center explosion, trail particles for the trajectory, and debris particles for scattered fragments. Each particle type has specialized attributes and rendering parameters, allowing realistic simulation while managing complexity through functional division

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the firework effect are rendered with different qualities and characteristics. The firework center uses bright, intense particles with rapid expansion, the trail uses fading particles along the trajectory path, and debris uses scattered particles with varied velocities. This local differentiation enhances realism while optimizing rendering resources

Inventive Principle:

Principle #3Local quality

2Reliability

If complex particle systems and rendering algorithms are used to achieve realistic firework effects, then visual quality improves, but computational resources and processing time increase

Engineering Contradiction:

Improvequality of firework visual effectVSAvoidcomputational energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system renders trail particles for a preset duration longer than strictly necessary for the main firework display. This partial extension of rendering time allows the trail to fade naturally, enhancing visual quality without requiring excessive computational resources for the entire particle lifecycle

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

Particle attributes such as transparency, size, and velocity are dynamically changed over time to create realistic firework effects. Trail particles gradually increase transparency and decrease size, while firework particles expand and then dissipate. These parameter transitions achieve high visual quality through efficient mathematical transformations rather than complex rendering operations

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If multiple particle sets and rendering steps are used to generate realistic firework visual effects, then visual richness improves, but processing complexity increases

Engineering Contradiction:

Improverichness of firework visual effectVSAvoidcomplexity of rendering process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rendering process is segmented into distinct steps: generating firework particle sets, generating trail particle sets, rendering firework particles, rendering trail particles, and superimposing results. This segmentation allows each step to be optimized independently while maintaining overall visual richness

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple particle sets (firework particles, trail particles, debris particles) are merged through superimposition to create the complete firework visual effect. The trail particle primitive models are combined with firework particle primitive models, allowing rich visual elements to be integrated efficiently in a single rendering pass

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method for generating a firework visual effect, an electronic device, and a non-transitory computer readable storage medium. The method for generating the firework visual effect comprises: determining a visual effect trajectory; according to the visual effect trajectory, generating a firework particle set and a tailing particle set in a three-dimensional space used for generating the firework visual effect; rendering the firework particle set to obtain a firework particle primitive model set; rendering the tailing particle set to obtain a tailing particle primitive model set; and performing superposition processing on the firework particle primitive model set and the tailing particle primitive model set to generate a firework visual effect, wherein at least some of multiple tailing particle primitive models in the tailing particle primitive model set are at least displayed for a preset time period. The method for generating the firework visual effect can visually achieve the visual effect of generating a firework tailing along with the movement of a firework center by means of multiple particle sets.
