Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing space suits fail to effectively compensate for hydrostatic pressure and maintain occupant comfort during high acceleration phases of rocket launch and atmospheric re-entry, leading to potential discomfort and risk of injury.
Innovation Solution
A hydrostatic pressure compensating space suit with a rigid, lightweight construction filled with a nontoxic fluid of similar density to the human body, featuring electro-mechanical or hydraulic servo-assisted joints that maintain constant pressure and volume, allowing for upright posture and mobility during high acceleration environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid space suit structure is used to maintain shape and provide structural support, then structural strength is improved, but adaptability to body movement and comfort deteriorates
Solution Approach 1:
The rigid space suit is divided into multiple segmented plates or segments that can move relative to each other at joints. This segmentation allows the suit to maintain rigidity in each segment while providing flexibility and adaptability at the joint regions, resolving the contradiction between structural strength and adaptability to body movement.
Solution Approach 2:
The suit incorporates dynamic joints that allow controlled movement between rigid segments. These joints enable the suit to adapt its configuration to match body movements while maintaining overall structural integrity, thus resolving the contradiction between rigidity and adaptability.
2Stability of the object's composition
If hydrostatic pressure is increased to counteract high g-forces during launch and re-entry, then occupant stability is improved, but occupant comfort and potential risk of injury deteriorates
Solution Approach 1:
The suit incorporates pressure regulation systems with feedback mechanisms that continuously monitor and adjust the hydrostatic pressure to match the actual g-forces experienced by the occupant. This feedback control ensures adequate support during high g-forces while preventing excessive pressure that could cause injury, thus resolving the contradiction between stability and safety.
Solution Approach 2:
The suit dynamically changes the hydrostatic pressure parameter in response to varying g-forces during different phases of flight. Pressure is increased during high g-force events like launch and re-entry to maintain stability, then reduced during normal conditions to ensure comfort and prevent injury, resolving the contradiction through parameter adaptation.
3Ease of operation
If fluid density is matched to human body density for neutral buoyancy, then occupant comfort is improved, but pressure control complexity increases
Solution Approach 1:
The suit uses a single adjustable parameter - fluid density - to achieve neutral buoyancy for the occupant. By matching the fluid density to the human body density, the system provides comfort through neutral buoyancy while keeping the control mechanism relatively simple, as density can be adjusted through a single parameter rather than multiple independent variables.
