Abstract: A method and system for strategically solving an innovative design problem are provided. A target analysis tool is determined according to a to-be-solved problem. An initial model is generated based on the target analysis tool. A target model is determined according to an interaction relationship among elements in the initial model and the target analysis tool. A problem characterization result of the target model is generated according to a preset interaction relationship. Retrieval information is generated according to the problem characterization result, based on which the retrieval is performed in a preset database to obtain target data. Different analysis tools can be used to analyze different to-be-solved problems. The retrieval is performed based on the problem characterization result to obtain the solution to the to-be-solved problem.

Abstract: A quick-detachable connecting device with a simplified thread structure includes a top nozzle, a connecting tube sleeve, a locking tube and a locking piece. The top nozzle is provided with a through hole, in which the connecting tube sleeve is assembled. The locking tube is accommodated in the through hole. An outer peripheral surface of the locking tube is provided with a second stopping structure, and an inner peripheral surface of the connecting tube sleeve is provided with a first stopping structure fitting the second stopping structure. The locking piece is movably arranged on the locking tube for circumferentially limiting or releasing the locking tube. A connection method using such connecting device is also provided.
