Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid support collars with curved shape are used to fix automatic water extinguishers on pipelines, then the extinguisher can be securely mounted, but the collar cannot be adapted to different pipeline diameters
Solution Approach 1:
The support collar transitions from a rigid, fixed-shape structure to a flexible, adaptable structure that can dynamically conform to different pipeline diameters. The collar is made of flexible material allowing it to be adjusted and secured on pipelines of varying sizes while maintaining mounting security through friction and elastic deformation.
Solution Approach 2:
The invention changes the physical parameter of the collar from rigid to flexible, enabling it to adapt its shape and size to match different pipeline diameters. This parameter change allows the same collar design to be universally applied across various pipeline sizes while maintaining secure mounting through the flexible material's ability to deform and conform.
2Adaptability or versatility
If multiple collar sizes are produced to adapt to different pipeline diameters, then adaptability is improved, but production costs and device complexity increase
Solution Approach 1:
The flexible support collar is designed as a universal component that can serve multiple functions across different pipeline diameters. Instead of producing multiple specialized collars for different sizes, a single flexible collar design can be universally applied to various pipeline diameters by adjusting its configuration, thereby reducing device complexity and inventory requirements.
Solution Approach 2:
By changing the material parameter from rigid to flexible, the invention enables a single collar design to adapt to different pipeline diameters through deformation rather than requiring multiple fixed-size collars. This eliminates the need for producing and managing multiple collar sizes, reducing both production costs and device complexity.
3Adaptability or versatility
If flexible clamping collars are used to adapt to different pipeline diameters, then adaptability is improved, but durability under high pressure may be compromised
Solution Approach 1:
The invention employs a flexible collar made of material capable of withstanding high pressure while maintaining its adaptability. The flexible shell is designed to deform elastically to conform to different pipeline diameters but possesses sufficient strength and rigidity when engaged to maintain its position and sealing under high water pressure conditions, thus ensuring durability.
Solution Approach 2:
The flexible collar is constructed from composite materials or specially formulated flexible materials that combine elasticity for adaptation with high strength for pressure resistance. This composite structure allows the collar to be adaptable to different pipeline diameters while maintaining durability and reliability under the high pressure conditions typical in fire protection systems.
