Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the heating coil and cooling liquid output device share the same moving path, then the quenching device can perform both heating and cooling functions, but the arrangement of circuit line and pipeline becomes difficult and complicated, resulting in large size and complicated structure
Solution Approach 1:
The patent divides the quenching device into separate heating and cooling components. The heating coil and spray cylinder are positioned at opposite sides of the workpiece holding assembly, with independent moving paths. This segmentation eliminates the complexity of arranging circuit lines and pipelines within a single path while maintaining both heating and cooling functions.
2Adaptability or versatility
If the heating coil and cooling liquid output device share the same moving path, then the quenching device can perform both heating and cooling functions, but the device size becomes large
Solution Approach 1:
The patent transitions from a single-dimensional moving path to a multi-dimensional arrangement. The heating coil and spray cylinder move along the central axis in opposite directions from opposite sides of the workpiece holding assembly. This spatial distribution in multiple directions reduces the overall device size while maintaining dual functionality.
3Device complexity
If a single cooling liquid output pipe is used, then the device structure is simpler, but the quenching effect is not good
Solution Approach 1:
The patent applies local quality by distributing multiple spray cylinders at different positions around the workpiece holding assembly. Each spray cylinder targets specific areas, ensuring uniform and effective cooling across the entire workpiece surface. This localized cooling approach significantly improves the quenching effect compared to a single output pipe.

AI summary
An inner-diameter quenching device is provided with a workpiece holding assembly for holding a workpiece to be quenched, a spray cylinder, and a heating coil. The workpiece has a central axis. The spray cylinder is disposed at a first side of the workpiece holding assembly and driven by a lifting assembly to move along the central axis into an inner diameter of the workpiece. The heating coil is disposed at a second side of the workpiece holding assembly and located on and movable along the central axis. The heating coil and the spray cylinder are separated and movable in opposite directions along the same center axis, which can further reduce the size of the quenching device, making it suitable for quenching a small inner-diameter workpiece. Besides, the spray apertures are inclined, so that the cooling liquid can be sprayed out more easily to enhance the quenching effect.
