Defibrillator Recording Instrument Side Paper Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Defibrillators have a limited screen-to-body ratio due to the occupation of space by display and recording components, making it inconvenient for users to operate and view information during defibrillation procedures.
Innovation Solution
The defibrillation device design incorporates a recording instrument that is partially assembled within the host housing, allowing printing paper to be outputted from the front surface while being placed or removed from other surfaces, thereby increasing the screen-to-body ratio by hiding the recording instrument behind the display component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the recording instrument is assembled within the host housing, then the screen-to-body ratio is improved, but the ease of operation for paper replacement deteriorates
Solution Approach 1:
The patent positions the paper replacement opening at the side of the host housing rather than on the front surface, utilizing the lateral dimension. This allows the display component to occupy maximum front surface area while the paper replacement function remains accessible through a side opening, resolving the spatial conflict between display size and operational accessibility.
2Area of moving object
If the recording instrument is hidden behind the display component, then the screen-to-body ratio is improved, but the device complexity increases
Solution Approach 1:
The side opening serves dual functions: it allows paper replacement access to the recording instrument while simultaneously maintaining a clean front surface for the display component. This multi-functional design element reduces the need for separate access mechanisms, thereby managing device complexity while achieving the desired display area expansion.

AI summary
A defibrillation device, medical device and recording instrument with a large screen-to-body ratio are disclosed. The defibrillation device includes a host housing including a first partial housing at a first side and a second partial housing at a second side; a display component assembled at the first partial housing; a recording instrument at least partially assembled at the host housing. The recording instrument is configured such that the printing paper inside the housing of the recording instrument is outputted to the first side, and the printing component is assembled at the housing of the recording instrument and located at the host housing to print the printing paper. An orthographic projection of the recording instrument at least partially overlaps with an orthographic projection of the display component on the first side. The printing paper is placed into or taken out from the housing of the recording instrument from the second side.
