Inflatable Air Chamber for Water-Resistant Body Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-resistant body covers do not effectively protect affected areas from water during showering, as they lack a secure and adjustable solution that combines water resistance with ease of use and adaptability.
Innovation Solution
A trapezoidal water-resistant cover with a continuously attached air chamber, hand pump, and interconnectable hook and loop fastener strips, where the air chamber securely engages around a user's limb when inflated, and the fastener strips secure the cover's edges for adjustable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing water-resistant body covers are used, then water protection is provided, but they lack secure engagement and adjustability around user's limb
Solution Approach 1:
The patent employs an air chamber that can be inflated to expand and conform to the user's limb, providing secure engagement. The air chamber is connected to a hand-operated pump that forces air into the chamber, allowing the cover to be adjusted to different limb sizes and shapes, thereby resolving the contradiction between reliable water protection and ease of operation.
2Ease of manufacture
If a fixed-size cover is used, then manufacturing is simple, but adaptability to various body parts is limited
Solution Approach 1:
The patent incorporates an inflatable air chamber that transforms the cover from a fixed-size structure to a dynamic, adjustable form. The air chamber can be inflated to different volumes, allowing the same cover to adapt to various body parts and user sizes, thus maintaining ease of manufacture while significantly improving adaptability.
Solution Approach 2:
The patent changes the volume parameter of the air chamber through inflation and deflation, enabling the cover to adapt to different body parts. This parameter change allows a single cover design to serve multiple purposes and fit various users, resolving the contradiction between manufacturing simplicity and adaptability.
3Device complexity
If the cover lacks an air chamber, then the structure is simple, but secure engagement around the limb cannot be achieved
Solution Approach 1:
The patent introduces an air chamber connected to a hand-operated pump, using pneumatic pressure to inflate the chamber and create secure engagement around the user's limb. This pneumatic mechanism provides reliable secure engagement while adding minimal structural complexity compared to rigid alternative solutions.
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 users to shower while protecting affected areas from water, providing a secure, adjustable, and water-resistant protective body cover that can be customized to various body parts.
Implementation Method 1
The air chamber (22) has an inflated position and an alternate deflated position. The hand pump (24) is attached to the air chamber (22). The air chamber (22) is configured to securely engage around a user's limb when the air chamber (22) is in the inflated position.
Implementation Method 2
The pair of hook and loop fastener strips (26) includes a first strip (40) and a second strip (42). The first strip (40) is continuously disposed on the exterior surface (38) of the right edge (28) of the cover (20). The second strip (42) is continuously disposed on the interior surface (36) of the left edge (30) of the cover (20).
