Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-toothed double-sided bayonet coupling is used for interlocking vessel portions, then the connection strength and reliability are improved, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The locking mechanism is segmented into simple L-shaped connection members distributed around the circumference, rather than a single complex multi-toothed bayonet coupling. Each connection member provides localized interlocking, and collectively they achieve the required connection reliability while significantly reducing manufacturing complexity
Solution Approach 2:
The invention replaces expensive, complex machined locking components with simpler, less costly connection members that can be manufactured more economically. The L-shaped members are simpler in form and can be produced with less machining, reducing overall manufacturing cost while maintaining functional reliability
2Strength
If a multi-toothed double-sided bayonet coupling is used for interlocking vessel portions, then the connection strength is improved, but the manufacturing cost and machining complexity increase
Solution Approach 1:
The locking function is distributed across multiple simple L-shaped connection members rather than concentrated in a single complex bayonet coupling. This segmentation allows each component to be simpler in design and easier to manufacture, while the collective arrangement maintains the required connection strength
Solution Approach 2:
Instead of creating a complex positive engagement mechanism with multiple teeth and corresponding grooves, the invention inverts the approach by using simple L-shaped members that engage through basic geometric interlocking. This inversion simplifies the manufacturing process while achieving adequate connection strength
3Reliability
If a complex locking mechanism is used for interlocking vessel portions, then the detonation resistance is improved, but the assembly process becomes more difficult and time-consuming
Solution Approach 1:
The locking mechanism is divided into multiple independent L-shaped connection members that can be assembled in a straightforward sequence. This segmentation allows for easier alignment and assembly compared to a complex integrated locking mechanism, while the collective arrangement of multiple members maintains the required detonation resistance
Solution Approach 2:
The invention uses simpler connection members that are easier to assemble than complex bayonet couplings. The reduced complexity of individual components translates to easier assembly operations and reduced assembly time, while the multiple-member arrangement ensures adequate detonation resistance
