Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firework batteries face a challenge in balancing pack size and stability, as larger expansion elements increase stability but also pack size, leading to higher transport costs due to increased risk of explosion, while smaller elements compromise stability.
Innovation Solution
A firework battery design featuring receiving parts and expansion elements connected via a vertical joint axis, allowing for a bordered footprint enlargement while maintaining a compact pack size, with foldable support elements and adjustable geometric arrangements to enhance stability and safety, and incorporating materials like cellulose for cost-effectiveness and environmental friendliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If expansion elements are made larger to increase stability, then stability is improved, but pack size increases leading to higher transport costs
Solution Approach 1:
The expansion elements are designed to be movable relative to the receiving parts through vertical joint axes, allowing the structure to dynamically adjust between a compact transport configuration and an expanded stable configuration. This dynamic capability enables the firework battery to achieve large footprint stability when needed while maintaining small pack size for transport.
Solution Approach 2:
The joint parts are oriented with vertical rotation axes perpendicular to the ground, enabling expansion elements to move in a vertical plane rather than horizontal. This dimensional change allows the structure to expand outward for stability while maintaining a compact vertical profile during transport, effectively utilizing the vertical dimension to resolve the size-stability contradiction.
2Volume of moving object
If expansion elements are made smaller to reduce pack size, then pack size is reduced, but stability is compromised
Solution Approach 1:
The movable connection through vertical joint axes allows small expansion elements to achieve large effective footprint when deployed. The elements can rotate outward to maximize the bordered footprint area, providing sufficient stability despite their small size when folded.
Solution Approach 2:
The expansion elements are pre-configured in a compact folded state for transport, then deployed outward when needed. This preliminary compact configuration allows small elements to be transported efficiently, while their deployment geometry provides the necessary stability during use.
