Universal Marking Bracket for Buried Pipe Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Structural elements such as pipes and skylights are often buried under snow or debris, leading to damage and safety hazards due to their invisibility, necessitating a device that can extend through burying materials to mark their presence.
Innovation Solution
A fastener made of spring steel with angled tabs that can flex to receive and hold a marker in place, ensuring it extends above burying materials, alerting to the presence of buried elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If structural elements are attached to surfaces, then they provide structural support, but they become invisible when buried under snow or debris
Solution Approach 1:
The marking system is segmented into two distinct components: a base portion that attaches to the structural element and a marker portion that extends outward. This segmentation allows the marker to remain visible while the base remains attached to the potentially buried structural element, resolving the contradiction between structural attachment and visibility.
Solution Approach 2:
The marker acts as an intermediary element between the buried structural element and the external environment. It transfers the information about the structural element's location to workers and equipment operators, preventing damage while allowing the structural element to remain buried for safety and insulation purposes.
2Reliability
If markers are attached to structural elements, then visibility is improved, but the markers may fall off or become dislodged
Solution Approach 1:
The fastening mechanism employs dynamic tabs that can flex and move. During installation, the tabs are pressed together to allow marker insertion, then they spring back to their original position to grip the marker securely. This dynamic behavior provides both easy installation and secure retention without requiring complex fastening operations.
Solution Approach 2:
The spring tabs automatically grip the marker upon insertion and maintain retention without additional fastening steps. The elastic properties of the tabs provide self-adjusting pressure to secure the marker, eliminating the need for separate locking mechanisms or complex installation procedures while ensuring reliable retention.
3Reliability
If the fastener uses angled tabs for marker retention, then marker security is improved, but the fastener structure becomes more complex
Solution Approach 1:
The tabs are designed with specific angular parameters (greater than 90 degrees from the base) that optimize their springing action and gripping force. By carefully selecting these geometric parameters, the fastener achieves reliable marker retention through the natural elastic recovery of the angled tabs, converting a potentially complex mechanism into a simple geometric solution based on material elasticity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The fastener effectively prevents damage and enhances safety by ensuring markers remain visible above snow or debris, reducing the risk of accidents and hazards associated with buried structural elements.
Implementation Method 1
The fastener is made of a spring steel material with flexible springing properties. The tabs being movable between the angle greater than 90 degrees relative to the base and a second angle approximately equal to approximately 90 degrees relative to the base. When the tabs are released, they will spring back towards their resisting position and exert a pressure on the marker, thereby preventing it from moving or falling.
