AED Carrying Case Counterweight Stability Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated external defibrillator carrying cases are unstable when in use, as the center of gravity shifts, causing the case to tip over, and the design biases the compartments to close improperly, making it difficult to operate the device securely.
Innovation Solution
A soft carrying case with a non-rigid material construction, including padding, and a design that maintains stability by allowing independent access to compartments without shifting the center of gravity, featuring a removable false floor or divider for quick access to medical items and a power receptacle for charging the defibrillator, ensuring secure operation and easy access to components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the first compartment is opened by rotating it away from the second compartment via hinge mechanism, then accessibility to the first compartment is improved, but the center of gravity shifts causing the case to tip over
Solution Approach 1:
The patent introduces a second compartment containing additional items that acts as a counterweight to balance the center of gravity. When the first compartment is opened, the second compartment's weight compensates for the shifted center of gravity, preventing the case from tipping over. This resolves the contradiction by maintaining stability while allowing easy access to the first compartment.
2Ease of operation
If the first compartment cover is hinged to allow opening, then accessibility is improved, but the design biases the compartments to close improperly
Solution Approach 1:
The patent introduces a floor structure as an intermediary element between the first and second compartments. This floor acts as a mechanical stop and guide that ensures the compartments close properly by preventing the cover from closing improperly. The intermediary floor structure maintains reliability of proper closing while preserving the hinged accessibility feature.
3Adaptability or versatility
If a false floor or divider is added for storage organization, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent divides the carrying case into multiple segments including a first compartment, second compartment, and a false floor or divider. This segmentation allows for organized storage of different items (defibrillator in first compartment, accessories in second compartment) while maintaining a manageable structural complexity through modular design. The segmentation principle resolves the contradiction by improving functionality through organized storage without excessive complexity.

AI summary
An automated external defibrillator soft carrying case includes a first compartment and a second compartment. The first compartment is connected to the second compartment by a hinge mechanism. The first compartment is also detachably connected to the second compartment. A first compartment ceiling is connected to the first compartment by a second hinge mechanism. The first compartment ceiling includes a transparent window.
