Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate mechanisms are used for elevating and rotating the bottle preform, then the functions are independent and reliable, but the space occupation is large and equipment costs are high
Solution Approach 1:
The patent combines the elevating mechanism and rotating mechanism into a single integrated structure. The elevating base moves vertically along guide rails while the preform insertion member rotates horizontally around a rotation axis, both within the same spatial envelope. This merging of functions reduces the overall space occupation and equipment costs while maintaining operational reliability through coordinated control of both movements.
Solution Approach 2:
The integrated mechanism serves multiple functions simultaneously: the elevating base provides vertical movement for insertion and removal, the preform insertion member provides horizontal rotation for uniform heating, and both are controlled by a single controller that coordinates their operations. This multi-functionality within a unified structure addresses the space and cost issues while preserving functional independence through electronic control.
2Device complexity
If the bottle preform is heated without rotation, then the heating process is simple, but the preform experiences local overheating
Solution Approach 1:
The patent introduces dynamic rotation of the preform insertion member during the heating process. The preform is rotated horizontally around the rotation axis while being heated by the heating barrel, ensuring uniform heat distribution across the preform surface. This dynamic movement prevents local overheating while maintaining relatively simple heating equipment, as the rotation mechanism is integrated into the existing elevating structure.
3Area of stationary object
If an integrated elevating and rotating mechanism is used, then space occupation and equipment costs are reduced, but the mechanism complexity increases
Solution Approach 1:
The integrated mechanism is segmented into distinct functional modules: the elevating base with guide rails for vertical movement, the preform insertion member with rotation capability for horizontal movement, and the heating barrel. Each module has a specific function, and their coordination is managed by a controller. This segmentation allows the complex integrated mechanism to be designed, manufactured, and maintained more easily while occupying less space than separate mechanisms.

AI summary
Provided are a preform elevating and rotating mechanism and a bottle preform heating device, which relate to the field of bottle blowing technologies. The preform elevating and rotating mechanism includes a bracket (41), a preform insertion assembly (42), an elevating drive assembly (43), and a rotation drive assembly (45). The bracket (41) is fixed on a carrier tray (22) of a carrier mechanism (2), where the carrier tray (22) is capable of driving the bracket (41) to rotate. The preform insertion assembly (42) includes an elevating base (421) and a preform insertion member (422), where the elevating base (421) is slidably mounted on the bracket (41), and the preform insertion member (422) is rotatably mounted on the elevating base (421). The elevating drive assembly (43) is configured to drive the elevating base (421) to move up and down relative to the bracket (41), so as to enable the preform insertion member (422) to be inserted into the bottle preform and enable the preform body of the bottle preform to be inserted into a heating barrel (31). The rotation drive assembly (45) is configured to drive the preform insertion member (422) to rotate.
