Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Propulsion systems using solid fuel often produce significant smoke and heat during launch, posing a risk to nearby individuals or occupants in buildings, as seen in fire-extinguishing rocket systems and throwing devices.
Innovation Solution
A propulsion system design featuring a first and second chamber with a retardant set positioned between them to delay combustion, reducing immediate smoke and heat emission by staging the propellant burn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If solid fuel propellant is burned in a single-stage propulsion system, then high thrust and rapid propulsion are achieved, but significant smoke and heat are emitted causing harm to nearby people
Solution Approach 1:
The single-stage propellant is divided into multiple segments (first propellant and second propellant) separated by a retardant set. This segmentation allows the combustion process to occur in stages, with the first propellant burning initially and the second propellant burning after a delay period, thereby reducing simultaneous smoke and heat emission while maintaining overall propulsion effectiveness
Solution Approach 2:
The propulsion system implements periodic combustion action through the staged burning of propellants. The first propellant burns during an initial period, then combustion is delayed by the retardant set, and the second propellant burns in a subsequent period. This periodic action reduces continuous harmful emissions while maintaining propulsion speed
2Object-generated harmful factors
If a retardant set is introduced to delay combustion between propellant stages, then smoke and heat emission are reduced, but device complexity increases
Solution Approach 1:
A retardant set is introduced as an intermediary component between the first and second propellants. This mediator delays the combustion transmission from the first propellant to the second propellant, allowing smoke and heat emission to be reduced by separating the combustion events in time while maintaining a relatively simple overall system structure
