Disposable Protective Suit with Pre-Adhesive Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal protective suits for containment zones face issues such as improper use, poor airtightness, discomfort, restricted vision, and difficulty in single-user implementation, along with challenges in sealing and post-use treatment.
Innovation Solution
A single-use protective suit with a jacket, hood, and pants, featuring an adhesive tape with a removable non-stick strip for easy sealing around sleeves, legs, and hood openings, and a polyolefin-based adhesive tape for secure attachment to additional equipment, ensuring easy donning and comfortable wear while maintaining watertightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tape is used to seal the joint between coverall and additional equipment, then sealing effectiveness is improved, but the amount of adhesive tape required increases significantly
Solution Approach 1:
The adhesive tape is pre-applied to the suit in strategic locations (sleeve cuffs, trouser leg cuffs, and hood opening) during manufacturing, with protective strips covering the adhesive surfaces. This preliminary action eliminates the need for extensive tape application during use, reducing both the quantity of tape needed and the complexity of the sealing process while maintaining reliable seals at critical junctions.
2Reliability
If adhesive tape is applied to ensure good seal, then sealing effectiveness is improved, but user freedom of movement is restricted due to discomfort
Solution Approach 1:
Adhesive tape is applied only at specific critical locations where seals are necessary (sleeve cuffs, trouser leg cuffs, and hood opening) rather than covering the entire suit. This localized application maintains sealing effectiveness at junction points while leaving the rest of the suit flexible and comfortable, preserving user freedom of movement.
Solution Approach 2:
The suit is designed as a single-use disposable item with pre-applied adhesive tapes. After use, the entire suit including the adhesive tapes is discarded at waste treatment centers. This eliminates the need for repeated tape applications and adjustments, ensuring optimal sealing performance without compromising comfort during the limited service life of the suit.
3Reliability
If a second person is used to assist donning and sealing, then sealing effectiveness is improved, but operational complexity increases
Solution Approach 1:
The suit is designed with self-sealing capabilities through pre-applied adhesive tapes with protective strips that users can easily remove and apply themselves. The tapes are positioned and sized to be manageable by a single user, eliminating the need for a second person to assist with donning and sealing operations while maintaining reliable seals.
4Reliability
If adhesive tape is used for sealing, then sealing effectiveness is improved, but ease of disposal is reduced
Solution Approach 1:
The suit is designed as a complete disposable unit with pre-applied adhesive tapes integrated during manufacturing. After single use in containment zones, the entire suit including all adhesive tapes is discarded as one unit at waste treatment centers. This approach maintains excellent sealing performance during use while simplifying disposal procedures, as no separate tape removal or cleaning steps are required.
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 solution allows for easy, single-user implementation of the suit, providing comfort and effective sealing without restricting movement, while being designed for efficient disposal after use.
Implementation Method 1
the adhesive tape is, after removal of the anti-adhesive strip, affixed to the additional equipment worn by the user to ensure a seal between the latter and the suit
Implementation Method 2
a removable anti-adhesive strip covering said adhesive tape along its entire length and part of its width
