Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a mechanical building drum is used to improve tire forming efficiency, then productivity is improved, but device complexity increases and requires frequent side drum replacement
Solution Approach 1:
The building drum incorporates an adjustable diameter mechanism that allows the drum to dynamically change its dimensions. The side drum can be adjusted along the axial direction and its diameter can be varied, transforming a static structure into a dynamic one that adapts to different tire specifications without requiring replacement.
Solution Approach 2:
The invention changes the physical parameters of the building drum, specifically the diameter and axial position of the side drum. By adjusting these parameters, the same drum can accommodate multiple tire grades, eliminating the need for replacement and reducing device complexity while maintaining high productivity.
2Adaptability or versatility
If side drum replacement is performed to process different tire grades, then adaptability is improved, but loss of time increases
Solution Approach 1:
The side drum is designed with dynamic adjustment capabilities, allowing it to change its axial position and diameter on-demand. This dynamic behavior enables the same drum to adapt to different tire grades instantly, eliminating the time-consuming replacement process while maintaining full adaptability.
Solution Approach 2:
The adjustable side drum serves multiple functions by accommodating various tire specifications through parameter adjustment. A single universal drum replaces multiple specialized drums, enabling the processing of different tire grades without replacement and significantly reducing time loss.
3Adaptability or versatility
If side drum replacement is performed frequently to match different tire grades, then adaptability is improved, but productivity decreases
Solution Approach 1:
The dynamic adjustment mechanism allows the side drum to quickly adapt to different tire grades without stopping production for replacement. This maintains continuous operation and high productivity while achieving full adaptability across different tire specifications.
Solution Approach 2:
The adjustable side drum enables continuous production by eliminating interruptions for drum replacement. The drum can be adjusted on-the-fly between different tire grades, maintaining the continuity of useful action and preventing productivity loss associated with frequent replacements.

AI summary
The present invention provides a building drum specification adjustment method and device. The building drum specification adjustment device includes a driving assembly, a transmission assembly and a diameter-variable member which are sequentially connected. The driving assembly includes a driving member and an output member. The building drum specification adjustment method includes: driving the output member (412) axially moving by the driving member (411) according to the size of the tire to be processed to a retracted position or an intermediate position, and enabling the diameter-variable member (43) to be located at the minimum diameter or the intermediate diameter; after a material is pasted or a steel ring is installed, the output member (412) is driven to move to an expansion position by the driving member (411), and the diameter-variable member (43) is changed to the maximum diameter; after the processing is completed, the output member (412) is driven by the driving member (411) to move towards the retracted position, the diameter of the diameter-variable member (43) is reduced, and the processed tire is taken down. The present invention solves the problem in the prior art that the replacement grade of a mechanical building drum is time-consuming and laborious.
