Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional connection devices with separate holders and nuts are used, then the connection structure is robust, but the assembling work is complex and time-consuming
Solution Approach 1:
The patent combines the holder and nut into a single integrated component called a 'fastening member'. This fastening member includes a holder portion that engages with the fluid pressure device and a nut portion that receives the screw part, eliminating the need for separate holder and nut components. This merging directly reduces assembly steps and improves workability while maintaining the robust connection function.
Solution Approach 2:
The fastening member is designed to perform multiple functions simultaneously: it holds the fluid pressure device (holder function) and secures the screw part (nut function) in a single integrated component. This multi-functionality reduces the number of parts needed and simplifies the overall connection structure while maintaining connection robustness.
2Productivity
If multiple separate parts (holder, nut, screw) are used for connection, then the connection is secure, but the assembly process is time-consuming
Solution Approach 1:
By merging the holder and nut into a single fastening member, the patent reduces the number of assembly steps. Instead of separately installing a holder and then a nut, the integrated fastening member is installed as one unit, directly improving assembly speed and reducing time loss.
Solution Approach 2:
The holder and nut are preliminarily integrated into a single fastening member during manufacturing. This preliminary action of combining components before assembly eliminates the need for separate installation steps during the assembly process, thereby improving productivity and reducing assembly time.
3Strength
If a simple cap structure is used, then the assembly is quick, but the connection strength may be compromised
Solution Approach 1:
The cap is integrated with the fastening member to form a unified structure. This merging ensures that the cap does not compromise connection strength but rather works together with the fastening member to secure the screw part, maintaining both strength and assembly simplicity.
Solution Approach 2:
The cap structure is designed to fit over and protect the fastening member components. This nesting arrangement allows the cap to be easily installed while providing structural support and protection, maintaining connection strength without complicating the assembly process.

AI summary
Connection devices for connecting together a filter, a regulator, and a lubricator, which constitute a fluidic unit, are each provided with: a base member having a hole; a pair of first and second fastening members which are mounted to one side surface and the other side surface of the base members; and first and second holders held by the first and second fastening members. The first and second holders are engaged with the engagement protrusions of the filter, the regulator, and the lubricator, and first and second nuts are engaged with the first and second fastening members through threads to connect the fluidic devices together through the first and second holders. Caps are fitted over the first holders and the first nuts.
