Resilient Void Insert Device for Wall Debris Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for protecting wall voids during construction are inadequate as they either cover adjacent wall surfaces, are not sturdy enough to resist air pressure, or become dislodged due to forces applied during finishing and insulation processes, leading to debris accumulation and material wastage.
Innovation Solution
A void insert device made of compressible material with a resilient perimeter shape and size, designed to fit snugly into wall voids, resisting movement and pressure while allowing easy removal and reuse, and featuring a manipulation structure for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing protection solutions are used to cover wall voids, then wall voids are protected against debris, but adjacent wall surfaces are covered requiring additional cleaning or repainting
Solution Approach 1:
The protection device is segmented into a frame structure with flexible curtains that can be independently positioned. The frame fits within the wall void opening while curtains drape into the void, separating the protection function from the wall surface, thus protecting the void without covering adjacent surfaces.
Solution Approach 2:
The protection function is extracted from a surface-covering approach and relocated to a void-inserting approach. The device is positioned within the wall void itself rather than covering the wall surface, eliminating the need to cover or damage adjacent wall surfaces while maintaining debris protection.
2Ease of operation
If lightweight protection materials are used, then ease of installation is improved, but the materials cannot resist air pressure from sprayers and trowels
Solution Approach 1:
Different parts of the device have different properties: the frame provides rigid structural support and pressure resistance, while the curtains provide flexible debris blocking. This local differentiation allows the device to resist air pressure from sprayers and trowels while remaining easy to install.
Solution Approach 2:
The device combines rigid frame material (for strength and pressure resistance) with flexible curtain material (for debris protection and ease of installation). This composite structure achieves both ease of installation and resistance to construction pressures.
3Object-affected harmful factors
If existing protection devices are used, then debris protection is provided, but devices become dislodged due to forces applied during finishing and insulation processes
Solution Approach 1:
The frame structure is designed to counteract forces applied during construction by distributing loads across the wall void opening. The rigid frame provides structural counter-resistance to air pressure from sprayers and trowels, preventing dislodgement while maintaining debris protection.
Solution Approach 2:
The device transitions from a two-dimensional surface covering to a three-dimensional void-inserting structure. The frame extends into the wall void while curtains drape downward, creating a multi-dimensional configuration that anchors the device securely against construction forces.
4Strength
If rigid protection structures are used, then pressure resistance is improved, but removal and reuse become difficult
Solution Approach 1:
The device combines rigid frame elements with flexible curtain elements. The rigid frame provides pressure resistance while the flexible curtains enable easy removal and reuse. The dynamic combination of rigid and flexible components allows the device to maintain structural integrity during use while facilitating straightforward installation and removal.
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
Effectively prevents debris from entering wall voids during construction and insulation, maintaining position under pressure from sprayers and trowels, and allows for easy cleaning and reuse, ensuring complete wall finishing without material loss.
Implementation Method 1
At least a portion of the void insert device adjacent to the perimeter surface of the insert device is formed of a compressible material permitting compression of the insert device to inset the insert device into the wall void
Implementation Method 2
The compressible material of the insert device may be characterized by having a degree of resiliency. The perimeter shape, the perimeter size, and the degree of resiliency of the compressible material of the insert device may be configured to press the perimeter surface of the insert device against the void surface of the wall void to resist movement of the insert device further into the void
