Piping Clamp Mechanism for Angular Adjustment in Electronic Device Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection mechanisms for electronic devices requiring angular adjustments about an axis suffer from poor workability due to the need for holding the device at a specific angle during nut fastening, potential angle changes during rotation, and the requirement for multiple tools, making operations cumbersome, especially in challenging installation sites.
Innovation Solution
A connection mechanism featuring cylindrical piping connectors with flange portions and guide holes, along with a piping clamp having half circular arc-shaped arm portions and a butterfly nut for secure fastening, allowing for angular adjustment and secure fixing without requiring additional tools or exerting rotational forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a nut is used to connect piping connectors, then the connection is secure, but the workability deteriorates when angular adjustment is required due to the need to hold the device at a specific angle during fastening
Solution Approach 1:
A positioning member is introduced as an intermediary component between the piping connectors. This positioning member has a positioning hole that fits over a positioning protrusion, temporarily fixing the angular position of the second piping connector relative to the first. This allows the connector to be positioned and held at the desired angle without requiring continuous manual holding during the nut fastening operation, thereby improving workability while maintaining connection security.
2Strength
If the nut is tightened to secure the connection, then the connection strength increases, but the angle may change during rotation, requiring readjustment
Solution Approach 1:
The positioning member is installed before the final tightening of the nut. The positioning protrusion fits into the positioning hole, pre-establishing the correct angular relationship between the piping connectors. This preliminary positioning action ensures that when the nut is subsequently tightened to achieve strong connection, the angular precision is already established and maintained, eliminating the need for readjustment.
3Reliability
If a conventional nut and threading mechanism is used, then the connection is secure, but multiple tools are required making the operation cumbersome
Solution Approach 1:
The positioning function and the connection function are merged into a integrated assembly. The positioning member with its positioning hole and protrusion features is combined with the piping connectors and nut in a single assembly operation. This merging eliminates the need for separate positioning tools and connection tools, reducing the number of tools required while maintaining both positioning accuracy and connection security.

AI summary
A connection mechanism for connecting electronic devices to each other, includes piping connectors, on which flange portions and guide hole portions are formed, and a piping clamp, which has arm portions having a groove formed to allow the flange portions to be fitted therein and a mechanism for fastening and fixing the arm portions to each other. The connection mechanism enhances workability when an electronic device, which requires an angular adjustment about on an axis of a connection portion thereof, is fixedly connected to another electronic device.
