Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If components are assembled in a single enclosure, then the device structure is simplified, but installation becomes difficult in small rooms and parts may become misaligned during assembly
Solution Approach 1:
The device is divided into multiple separate enclosures (first enclosure for disperser and accumulator, second enclosure for suction device and pressure roller), allowing each module to be installed independently in small rooms while maintaining overall system functionality through standardized connection interfaces
2Device complexity
If components are assembled in a single enclosure, then the device structure is simplified, but misalignment occurs during assembly resulting in performance and quality problems
Solution Approach 1:
By segmenting the device into separate enclosures with standardized connection interfaces, each module can be precisely aligned and assembled independently, preventing misalignment issues that occur when assembling large integrated structures
Solution Approach 2:
Connection interfaces are pre-designed and pre-positioned on each enclosure, allowing components to be pre-aligned and pre-assembled in the correct positions before final integration, ensuring precise alignment and preventing misalignment during the assembly process

AI summary
A web forming device and sheet manufacturing apparatus can manufacture sheets of desired dimensions regardless of the location. The web forming device includes: a disperser configured to disperse in air defibrated material containing a defibrated material of defibrated fiber; an accumulator configured to accumulate the defibrated material dispersed by the disperser; a housing enclosing a space between the disperser and the accumulator; a suction device disposed on the opposite side of the accumulator as the disperser; and a fastening assembly that can be disassembled into a first fixing assembly and a second fixing assembly. The disperser is affixed to the first fixing assembly, and the accumulator, housing, and suction device are affixed to the second fixing assembly.
