Pipe Sensor Mount With Rotating Jig for Fast Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment devices for information acquisition devices in pipe conduits face challenges in securing space for fastening and complicating the fastening work, making it difficult to attach and detach these devices efficiently.
Innovation Solution
An attachment device with a mount, holder, and restriction jig that includes first and second restriction portions to engage with the mount, allowing for easy attachment and detachment by rotating the jig in a specific direction, and a holder with a shaft and guide to position the information acquisition device accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional fastening methods (bolts, nuts) are used to attach the through flange and inspection rod, then the connection strength is sufficient, but the space for performing fastening work becomes difficult to secure and the fastening work becomes complicated
Solution Approach 1:
The attachment device is divided into separate components: a through flange with a through hole, a holder that fits into the hole, and a restriction jig. This segmentation allows the holder to be attached without requiring complex fastening operations in confined spaces, while still achieving secure connection through the multi-component design
Solution Approach 2:
The restriction jig acts as an intermediary tool that facilitates the attachment and detachment of the holder to the through flange. The jig includes restriction portions that engage with projections on the flange, providing a mechanical advantage that enables easy operation without compromising connection strength
2Reliability
If conventional fastening methods are used, then the connection is secure, but the fastening work becomes complicated and time-consuming
Solution Approach 1:
The holder is designed with a through hole and the through flange is designed with corresponding projections before assembly. The restriction jig is pre-configured with engagement portions that match these features. This preliminary design of complementary geometries enables rapid attachment by simply inserting and engaging the components, significantly reducing attachment time while maintaining reliable connections
Solution Approach 2:
The attachment system transitions from static fastening (bolts and nuts requiring multiple steps) to a dynamic engagement mechanism where the restriction jig can be inserted, rotated to engage with projections, and locked into place. This dynamic process reduces attachment time while ensuring reliable connection through the engagement geometry
3Ease of operation
If the holder is detachably attached to allow easy removal, then the ease of operation improves, but the connection strength may be compromised
Solution Approach 1:
The connection system is segmented into the through flange, holder, and restriction jig as separate components. The holder can be detachably attached to the flange through the through hole, allowing easy removal when needed. The segmentation enables both easy detachment and sufficient connection strength through the designed engagement interface
Solution Approach 2:
The restriction jig serves as an intermediary that provides the mechanical means for both secure attachment and easy detachment. When engaged with the projections on the flange, it secures the holder firmly. When detached, it allows the holder to be easily removed. This intermediary mechanism balances connection strength with ease of operation
