Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard-size core holding system is used, then the system structure is simple and easy to manufacture, but it cannot accommodate cores of non-standard sizes
Solution Approach 1:
The patent applies the dynamics principle by making the core holding system adjustable through interchangeable plugs with different inner diameters. The plug can be dynamically changed to match different core sizes, transforming a static system into an adaptive one. This resolves the contradiction by enabling size adaptability while maintaining a relatively simple overall structure through modular components.
Solution Approach 2:
The patent implements parameter changes by varying the inner diameter parameter of the holding plugs. Multiple plugs with different diameter parameters are provided, allowing the system to adapt to cores of various sizes by selecting the appropriate plug. This directly addresses the adaptability requirement while keeping each individual plug simple in structure.
2Adaptability or versatility
If a large-volume core holding system is used to accommodate various core sizes, then adaptability is improved, but the system cannot be placed into constant-temperature equipment
Solution Approach 1:
The patent applies segmentation by dividing the core holding system into separate functional components: a sleeve and interchangeable plugs. This segmentation allows the main body (sleeve) to remain compact and fit within constant-temperature equipment, while adaptability is achieved through separate plug components that can be exchanged as needed. This resolves the contradiction between compact volume and size adaptability.
Solution Approach 2:
The patent implements universality through the design of the sleeve that can universally accommodate different plugs with varying inner diameters. The universal sleeve design allows a single compact body to serve multiple functions by interfacing with different specialized plugs, enabling adaptability without increasing the overall system volume beyond the sleeve's fixed dimensions.
3Adaptability or versatility
If standard core holding systems are used, then manufacturing and operation are simple, but cores that do not meet standard sizes cannot be held
Solution Approach 1:
The patent applies dynamics by enabling the holding system to adapt its inner diameter dynamically through plug selection. The system transitions from a fixed configuration to an adjustable one, allowing compatibility with various core sizes while maintaining operational simplicity through a straightforward plug-in mechanism that requires minimal complex procedures.

AI summary
The present disclosure discloses a core holding system, comprising: a sleeve in which a cavity capable of accommodating a core is formed; an adjustment plug set comprising a plurality of adjustment plugs having grooves of different diameters, wherein any one of the adjustment plugs is dismountably connectable to the sleeve, and when the adjustment plug is mounted on the sleeve, an end of the adjustment plug having the groove is insertable into the sleeve while abutting against the core; a heating module provided to sheathe the sleeve; and a thermal insulation module provided to sheathe the heating module. Before the core is held, the operator may select a matched adjustment plug from the adjustment plug set according to a diameter of a core to be held, so that a diameter of the groove of the adjustment plug is matched with a diameter of an end of the core, thereby ensuring that the end of the core can be engaged in the groove, thus ensuring that the core holding system can stably and tightly engage the core, and preventing the held core from being shifted or loosened.
