Defibrillator Monitor Rotatable Cover for Compact Interface Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing defibrillator monitors with slidable covers occupy significant space, affecting the structural integrity and stability of the housing, and are prone to foreign material ingress when not in use.
Innovation Solution
A rotatable cover system is introduced for interface elements, allowing them to be covered and exposed without requiring additional space, using a central portion and protruding portions for each element, with a biasing mechanism to maintain the cover in the protective position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a slidable cover is used to cover the interface element, then the interface element is protected from foreign material ingress, but the device occupies significant space and the housing structural integrity is compromised
Solution Approach 1:
The patent transitions from a linear sliding motion (one-dimensional) to a rotational motion (circular path). The cover rotates about an axis to move between covering and uncovering positions, utilizing angular displacement instead of linear displacement. This dimensional change allows the cover to achieve the same protective function while occupying less space, as the rotational path can be contained within a compact circular area rather than requiring extended linear travel space.
Solution Approach 2:
The patent employs a dynamic cover mechanism that rotates between two functional positions (covering and uncovering) rather than remaining static. The cover can be actively positioned by the user through rotation, allowing it to adapt between protecting the interface element and allowing access. This dynamic positioning enables space efficiency while maintaining protection when needed.
2Reliability
If a slidable cover is used to cover the interface element, then the interface element is protected, but the housing becomes less robust and stable
Solution Approach 1:
By changing from linear sliding to rotational motion, the cover mechanism no longer requires large linear excursions that would compromise housing strength. The rotational movement can be contained within a compact arc, reducing the stress and structural compromises needed in the housing for slide track accommodation.
Solution Approach 2:
The cover is designed to be positioned in the covering state by default (protected position), with the understanding that users will rotate it to the uncovering position only when needed. This preliminary protective positioning allows the housing to be designed with stronger structural integrity, as the cover provides ongoing protection without requiring the housing to accommodate large mechanical movements.
3Volume of stationary object
If a rotatable cover is used instead of a slidable cover, then space occupation is reduced, but the ease of operation may be affected
Solution Approach 1:
The rotatable cover provides dynamic positioning capability, allowing users to rotate it between covering and uncovering states. This rotational dynamics offers intuitive operation through natural hand motions and provides tactile feedback during rotation, maintaining ease of operation while achieving compact space utilization.
