Hinged Head Attachment for Secure Temporary Dust Partitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temporary support pole systems for construction sites lack effective and durable solutions for securing flexible partition materials, leading to inadequate containment of dust and debris, and potential damage to ceilings and retainer elements.
Innovation Solution
A head attachment with a pivotally movable retainer element and latching mechanism for secure engagement with temporary support poles, allowing easy installation and removal of flexible partition materials, featuring a U-shaped rim and gasket for enhanced retention and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If friction-based retention is used to hold partition material, then the system is simple in structure, but the retention is inadequate and causes damage to ceilings and retainer elements
Solution Approach 1:
The retainer element is designed to be movable between a first position (open) and a second position (closed), allowing dynamic adjustment. When closed, it mechanically engages with the partition material edge, providing reliable retention without relying on friction. This dynamic mechanism resolves the contradiction by offering strong retention when needed while maintaining structural simplicity through a single movable component.
Solution Approach 2:
The retainer element is nested within the head attachment body, fitting into a recessed area. This nesting arrangement provides mechanical retention through geometric interlocking rather than friction, while keeping the overall structure compact and simple. The retainer element can be inserted and secured within the head attachment without adding significant structural complexity.
2Reliability
If a hinged retainer element with latching mechanism is used, then the retention is secure and durable, but the operation becomes more complex
Solution Approach 1:
The hinged retainer element provides dynamic movement between open and closed positions, enabling easy installation by opening the retainer, placing the partition material, and closing the retainer for secure engagement. The hinge mechanism allows smooth operation without complex assembly steps, resolving the contradiction between secure retention and ease of operation.
Solution Approach 2:
The head attachment is segmented into distinct functional components: the body, the hinged retainer element, and the latching mechanism. This segmentation allows each component to perform its specific function independently - the retainer provides mechanical retention while the latch secures it in place - making the overall operation simpler and more reliable than a monolithic design.
3Strength
If the retainer element is made robust for durability, then it can withstand construction environment, but it may cause damage to ceilings upon contact
Solution Approach 1:
The retainer element is designed with differentiated local qualities: the portion that contacts the partition material is robust and durable to withstand construction environments, while the portion that may contact the ceiling is made of softer, more compliant material. This local quality differentiation resolves the contradiction by providing durability where needed while preventing damage where contact with the ceiling might occur.
Solution Approach 2:
A cushioning element or compliant material is incorporated at the ceiling-contacting surfaces of the retainer element before any potential contact occurs. This beforehand cushioning prevents damage to the ceiling while allowing the retainer element to maintain its robust, durable construction for withstanding construction environment stresses.
