Inflatable Scaffolding Cover Gap Filling Pneumatic Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection systems for scaffolds are cumbersome to attach and may not effectively withstand high winds or prevent damage from environmental factors like rain, hail, snow, and dust, as they require fixation to the construction and can be prone to flapping or excessive pressure.
Innovation Solution
An inflatable body is used to fill and fix gaps between scaffolding portions and the construction, providing a flexible and adjustable cover that can be inflated to fit standardized gaps, reducing the need for additional fixation elements and allowing the structure to remain intact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If tarpaulins are attached to scaffolding to create a closed protective space, then the workspace is protected from environmental elements, but the attachment process becomes cumbersome and requires fixation to the construction
Solution Approach 1:
The patent uses an inflatable barrier element that can be inflated to expand and fill the gap between the scaffolding and the construction. This pneumatic approach eliminates the need for complex mechanical attachment systems, as the inflated element naturally seals against the construction surface through pressure, providing both protection and easy installation.
Solution Approach 2:
The barrier element is designed as a flexible inflatable structure that can conform to the contours of the construction surface. This flexibility allows the element to adapt to various gap sizes and construction geometries without requiring rigid fixation points or complex attachment mechanisms.
2Object-affected harmful factors
If a closed cover is placed on the scaffold to protect from weather, then environmental protection is improved, but high wind strengths cause the cover to flap or require removal
Solution Approach 1:
The inflatable barrier element is designed to be dynamically adjustable through inflation pressure. When wind loads increase, the internal pressure can be increased to maintain the protective barrier's position and shape, allowing the system to adapt to varying wind conditions rather than being a static structure that must be removed.
Solution Approach 2:
The inflated barrier element creates its own stabilization through internal pressure, eliminating the need for external anchoring to the construction. The element serves itself by using inflation pressure to maintain its protective function against wind and weather without requiring additional fixation systems.
3Stability of the object's composition
If tarpaulins are secured to scaffolding stays, then workspace enclosure is achieved, but excessive pressure may damage the scaffolding portions
Solution Approach 1:
The inflation pressure of the barrier element can be precisely controlled and adjusted as a parameter. This allows optimization of the pressure to achieve sufficient enclosure stability while remaining below the threshold that would damage the scaffolding structure. The distributed pressure from the inflated element is more favorable than concentrated loads from mechanical fixation.
4Ease of operation
If fixation elements are provided to attach the cover to the construction, then the cover can be secured, but the construction must be damaged or altered for fixation
Solution Approach 1:
The inflatable barrier element uses pneumatic pressure to create a seal against the construction surface without requiring mechanical penetration or attachment. The inflation pressure creates sufficient friction and normal force to secure the element in position while leaving the construction completely intact.
Solution Approach 2:
The inflatable barrier element acts as an intermediary between the scaffolding and the construction, filling the gap and creating protection without directly fixing to the construction. This intermediate approach allows the element to be secured through inflation pressure alone, eliminating the need for fixation elements that would damage the construction.
