Removable Sensor Cables in Protective Garments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective clothing systems require permanent connection of electronic components, leading to premature failure and high replacement costs when these components become damaged, as they are often washed together with the garment and cannot be easily replaced.
Innovation Solution
The protective clothing design allows for the removable and replaceable integration of sensor and display elements, with a cable arrangement that can be detached and reattached, enabling continued use of the garment and preventing unnecessary wear and tear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic components are permanently connected to the protective clothing, then the monitoring system remains stable and functional, but the components cannot be replaced and must be disposed of with the garment when damaged
Solution Approach 1:
The protective clothing is divided into separate washable layers (outer fabric, moisture barrier, lining) and non-washable electronic components. The cable arrangement passes through openings in the textile layers, allowing electronic components to be detached from the garment. This segmentation enables the clothing to be washed and maintained separately from the electronic components, solving the contradiction between reliability and ease of repair.
2Stability of the object's composition
If electronic components are washed together with the protective garment, then the garment maintains its protective properties, but the electronic components become damaged and fail prematurely
Solution Approach 1:
The electronic components (sensor element, display element, control unit) are extracted from the washable textile structure of the protective clothing. The cable arrangement allows these components to be removed from the garment before washing, so they can be stored separately and protected from water and detergent damage while the garment maintains its protective properties through regular washing.
3Ease of operation
If the cable arrangement passes through openings in the moisture barrier, then connectivity is maintained, but moisture can penetrate through the openings and compromise the system
Solution Approach 1:
The cable arrangement acts as an intermediary element that passes through openings in the moisture barrier while maintaining both cable connectivity and moisture protection. The cable arrangement is designed to seal around the cable passage, allowing electrical connectivity to be maintained while preventing water and moisture from penetrating through the opening and compromising the electronic components or inner layers of the protective clothing.

AI summary
The invention relates to a protective garment (1), in particular a protective jacket, comprising a main part (3) covering the upper body of a wearer of the protective garment (1), which can be opened and closed in the chest area (7) and abdomen (8) of the wearer, and two sleeves (104, 204) branching off from the main part (3) on opposite sides in the shoulder area (6) of the wearer, as well as a monitoring system regarding the current environmental conditions for the wearer, wherein the monitoring system comprises at least one sensor element (16) for detecting an environmental parameter and/or at least one display element (117, 217, 317) for optical and/or acoustic indication of a condition, and a cable arrangement (15) connected to the at least one sensor element (16) and/or to the at least one display element (117, 217, 317) for connection to a control unit (14).wherein the cable assembly (15) runs at least in the main part (3) of the protective garment (1) and is arranged at least partially between two textile layers of the protective garment (1). In order to further develop the protective garment (1) in such a way as to ensure the proper functioning of the cable assembly (15), the sensor elements (16) and the display elements (117, 217, 317), while nevertheless avoiding the need to replace the entire protective garment (1) after the possible wear or failure of the cable assembly (15), the sensor elements (16) and/or the display elements (117, 217, 317), it is provided that the cable assembly (15) together with the at least one sensor element (16) and/or with the at least one display element (117, 217, 317) is removable from the protective garment (1).
