Filter Tape With Coding For Multi-Walled Plate Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent and translucent plate materials used in canopies and light corridors are prone to dirt accumulation and micro-organism growth due to airborne dust, which is visually discernible, requiring a filter tape that maintains ventilation while preventing dust entry and allowing condensation drainage, and also needs to be traceable for origin after installation.
Innovation Solution
A filter tape with a dust-tight but ventilating base, featuring a unique coding through digital printing with ink or polymer resin for identification and adjustable permeability, applied over the end surface of plate materials, ensuring both ventilation regulation and origin tracing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cavity channels are closed in dust-tight manner, then dust and micro-organism entry is prevented, but ventilation and condensation drainage are impaired
Solution Approach 1:
The filter tape employs a porous non-woven fabric base that allows selective passage of air and moisture while blocking dust and micro-organisms. The porous structure enables ventilation and condensation drainage while maintaining dust-tight closure, resolving the contradiction between sealing and breathability.
Solution Approach 2:
The filter tape uses a flexible non-woven fabric that can be locally closed by a covering layer. This thin film structure provides the necessary sealing when needed while maintaining the ability to ventilate and drain through the porous base material, achieving both dust protection and airflow control.
2Object-affected harmful factors
If the filter tape is provided with a covering to regulate ventilation, then dust-tight closure is improved, but the ability to trace origin is lost
Solution Approach 1:
The filter tape is pre-provided with a covering layer that includes a coding element during manufacturing. This preliminary action ensures that the origin information is embedded in the product before installation, allowing traceability to be maintained even when the tape is used to close cavity channels in a dust-tight manner.
Solution Approach 2:
The coding element on the covering layer serves as a copy or identifier of the filter tape's origin and specifications. This coding allows the tape to be traced back to its manufacturer and production details without compromising the dust-tight closure function, as the coding is integrated into the covering layer rather than requiring separate identification systems.
3Illumination intensity
If transparent plate material is used to allow sunlight entry, then illumination is improved, but dirt accumulation and micro-organism growth become visually discernible
Solution Approach 1:
The porous non-woven fabric filter tape allows controlled passage of air and light while blocking dust and micro-organisms. The porous structure enables the material to maintain illumination transmission through the plate material while preventing the accumulation of dirt and growth of micro-organisms that would otherwise be visually discernible.
Solution Approach 2:
The filter tape serves as a protective barrier that can be easily replaced if contaminated. Rather than attempting to maintain the transparency of the plate material indefinitely, the disposable filter tape provides a cost-effective solution that prevents dirt accumulation and can be replaced when necessary, maintaining the illumination function while addressing the contamination issue.
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 filter tape effectively prevents dust and micro-organism entry while allowing moisture drainage and provides a means to uniquely identify the origin of the plate material, facilitating accountability and easy tracing in the production chain.

AI summary
Multi-walled plate material comprises a set of in particular at least translucent plate bodies (10,20) which are spatially separated from each other by successive separating bodies (15) while enclosing a series of cavity channels (30). The cavity channels debouch at an end surface (25) of the set of plate bodies (10,20). A ventilating but substantially dust-tight filter tape (40) is arranged over the end surface (25) and closes the cavity channels (30) in dust-tight but ventilating manner. The filter tape (40) comprises for this purpose a dust-tight but ventilating base on which a discontinuous covering (51..53) is provided which closes the base locally in at least substantially fully airtight manner. The covering features a characteristic coding (51) which is able and configured to identify the filter tape uniquely according to an origin and/or a destination.
