Solution Overview
Problem
Gas supply devices face challenges in balancing ergonomics, lightness, and impact resistance, requiring a structure that is both rigid to support high-pressure bottles and capable of absorbing energy during falls without leading to serious accidents.
Innovation Solution
Incorporating rigid reinforcement bars between rows of bottles, connected to the frame's transverse beams, which generate vertical force and distribute impact energy by allowing deformation in specific zones, thereby enhancing impact resistance without excessive weight or complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame structure is made rigid to support high-pressure bottles during lifting, then the structural strength and stability are improved, but the device weight increases and impact energy absorption capacity deteriorates
Solution Approach 1:
The frame structure is divided into rigid zones (transverse beams, corner posts) and deformable zones (upper vertical posts above transverse beams). This segmentation allows different parts to serve different functions: rigid parts provide structural strength for lifting, while deformable parts absorb impact energy, resolving the contradiction between strength and weight.
Solution Approach 2:
Different parts of the frame have different mechanical properties. The transverse beams and lower portions are designed to be rigid for strength, while the upper vertical posts are designed to be more flexible for energy absorption. This local differentiation of quality allows the structure to be both strong and lightweight.
2Stability of the object's composition
If the frame structure is made rigid to ensure stability during lifting, then the structural stability is improved, but the impact resistance deteriorates due to inability to absorb impact energy
Solution Approach 1:
The frame is segmented into stable lower portions (transverse beams, corner posts) and deformable upper portions (vertical posts above transverse beams). The segmentation maintains overall structural stability while allowing localized deformation to absorb impact energy, resolving the contradiction between stability and impact resistance.
Solution Approach 2:
The potential harm of impact is converted into beneficial energy absorption through controlled deformation of the upper vertical posts. The deformable zones are designed to yield under impact, converting the harmful impact energy into deformation work, thereby protecting the bottles and reducing overall impact resistance requirements.
3Object-affected harmful factors
If robust cylinders and frame components are designed to absorb impact energy, then the impact resistance is improved, but the device complexity and weight increase
Solution Approach 1:
Instead of making the entire frame robust and complex, only specific local zones (upper vertical posts above transverse beams) are designed with different mechanical properties for energy absorption. This localized approach to quality differentiation achieves impact resistance without excessive device complexity.
Solution Approach 2:
The mechanical parameters (rigidity, yield strength) of specific frame components are changed to create deformable zones. By adjusting parameters like wall thickness or material properties in localized areas, the frame gains impact absorption capability without requiring a complete redesign of the entire structure, thus avoiding excessive complexity.
