Sampling Point Clip for Aspirated Smoke Detector Pipe Diameter Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In aspirated smoke detector systems, identifying the diameter of sampling points on pipes is challenging due to their deployment underneath ceilings, which obstructs the installer's view, leading to potential errors in hole sizing during installation.
Innovation Solution
A clip system that grips the pipe circumference, features a size-indicating indicia to visually identify the hole diameter, allowing for accurate determination and potential alteration of the hole size, using color and symbol combinations to represent different diameters.

Engineering Contradiction Analysis
1Productivity
If pipes are deployed directly underneath a ceiling, then the pipe network can be installed in a compact and efficient manner, but the installer cannot visually identify or view the size of holes to be drilled
Solution Approach 1:
A template is introduced as an intermediary tool that bridges the gap between the installer and the pipe. The template carries hole size information externally (on its surface) and physically positions the correct hole size on the pipe, allowing the installer to identify and drill holes accurately without needing to see the hole size directly on the pipe itself.
Solution Approach 2:
The hole size information is transferred from the two-dimensional pipe surface to the three-dimensional template structure. The template provides external surfaces and edges that display hole size information in a visually accessible manner, separate from the pipe's concealed position under the ceiling.
2Productivity
If the installer cannot view the hole size on the pipe, then installation speed may be maintained, but the accuracy of hole diameter identification deteriorates
Solution Approach 1:
The correct template corresponding to the required hole size is selected and positioned on the pipe before drilling begins. This preliminary action ensures that the hole size information is already correctly aligned and visible to the installer, eliminating the need for measurement or judgment during the actual drilling operation.
Solution Approach 2:
The template serves as a mediator that translates the required hole size into a visually identifiable form. By placing the template on the pipe, the installer can accurately identify the correct hole diameter through the template's external indicators without compromising installation speed.
3Productivity
If standard holes are drilled into pipes without visual reference, then the installation process can proceed quickly, but errors in hole sizing occur
Solution Approach 1:
The template acts as a reliable intermediary that guarantees correct hole sizing. Its physical presence on the pipe provides a constant reference during the drilling operation, ensuring that holes are drilled at the correct positions with the correct diameters, thereby improving reliability without significantly impacting throughput.
Solution Approach 2:
The template is designed to be self-aligning and self-indicating. Once positioned on the pipe, it automatically provides the correct hole size information and positioning without requiring additional verification or adjustment by the installer, maintaining quick installation while ensuring accuracy.
