Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dual-output shaft drive motor is adopted to drive the belts at both sides, then the transmission connection is achieved, but the assembly structure becomes very complex and the connection sleeve is easy to slip leading to light leakage
Solution Approach 1:
The patent extracts and removes the complex connection sleeve component from the dual-output shaft drive motor system. Instead of using a connection sleeve to connect the transmission rod to the belt assembly, the patent directly connects the transmission rod to the belt assembly through simplified mounting holes and fixing screws, eliminating the intermediate connection sleeve that was prone to slipping and causing light leakage.
Solution Approach 2:
The patent segments the transmission system into independent modules: the drive motor, the transmission rod, and the belt assembly. Each module can be assembled and adjusted independently, with the transmission rod serving as a simple rotational connector rather than a complex transmission mechanism. This segmentation simplifies the overall assembly structure while maintaining reliable power transmission.
2Ease of manufacture
If a single output shaft drive motor is used with gear assembly and transmission rod, then the cost is reduced, but it is difficult for the movable cross beam to keep horizontal leading to light leakage
Solution Approach 1:
The patent incorporates preliminary adjustment mechanisms in the form of adjustable mounting holes and positioning features that allow the movable cross beam to be pre-adjusted to a horizontal position during assembly. The belt tensioning mechanism and cross beam mounting structure enable preliminary alignment before final fixation, ensuring horizontality is achieved during the assembly process rather than requiring perfect manufacturing precision.
Solution Approach 2:
The patent introduces dynamic adjustment capabilities through the belt tensioning mechanism and adjustable mounting holes. These features allow the system to be dynamically adjusted during assembly and maintenance to maintain the movable cross beam horizontality, transforming a static precision requirement into a dynamic adjustment process that compensates for manufacturing tolerances.
3Strength
If transmission rods of regular quadrangle or hexagon structure are used, then the mechanical connection is achieved, but angle errors of 90 or 60 degrees occur making it difficult to assemble the movable cross beam horizontally
Solution Approach 1:
Instead of using a regular polygon-shaped transmission rod that imposes fixed angular positions (90 or 60 degrees), the patent inverts the approach by using a circular transmission rod that allows continuous rotational adjustment. The mounting holes in the belt assembly and cross beam are positioned to accommodate this circular rod, enabling precise angular alignment to achieve horizontality rather than being constrained to fixed angular positions.
4Manufacturing precision
If high requirements are made for assembling personnel to adjust belts at both sides, then the movable cross beam can be horizontally assembled, but the assembling work becomes troublesome, difficult and time and labor-consuming
Solution Approach 1:
The patent incorporates self-aligning and self-adjusting features in the assembly structure. The adjustable mounting holes with clearance allow the components to self-align during assembly, and the belt tensioning mechanism enables automatic tension equalization. These self-service features reduce the need for skilled manual adjustment while maintaining horizontal alignment, making the assembly process more forgiving and less time-consuming.
Solution Approach 2:
The patent includes preliminary positioning features such as pre-drilled mounting holes at specific angles and positions, as well as pre-adjusted belt lengths. These preliminary actions are built into the components during manufacturing, so that during assembly the worker only needs to connect the components rather than perform complex adjustments, significantly reducing assembly time and skill requirements while ensuring proper horizontality.
