Non-planar Display Screen for Curved Surgical Device Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional static labels on electromechanical handheld surgical devices are limited in space, unable to provide comprehensive information in multiple languages, and cannot dynamically update with software changes or accommodate various surgical operations, especially in devices with curved ergonomic designs where flat display screens are restrictive.
Innovation Solution
A non-planar, flexible or curved display screen that adjusts its information display based on the device's orientation, using a processor, memory, and orientation detector to optimize the display area, allowing for dynamic information presentation and language selection, while fitting seamlessly within the device's ergonomic design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a flat display screen is used in a curved housing, then the display can show dynamic information, but the display area is restricted and space is wasted
Solution Approach 1:
The display screen is designed with a curved surface that matches the ergonomic contour of the housing. This curvature allows the display to conform to the housing shape, maximizing the use of available space while maintaining the ergonomic design. The curved display screen eliminates wasted space between a flat screen and the curved housing surface.
2Loss of information
If a static label is used to describe device features, then the device structure remains simple, but the label cannot provide comprehensive information in multiple languages or update with software changes
Solution Approach 1:
The display screen dynamically updates its content based on software changes, selected languages, and operational modes. Instead of a static label, the display can show different information in real-time, adapting to user preferences and device state. This dynamic capability allows comprehensive information presentation without increasing structural complexity.
Solution Approach 2:
The display screen serves multiple functions: showing device information, providing multilingual support, displaying operational status, and updating with software changes. This single multi-functional display replaces what would otherwise require multiple static labels in different languages and configurations.
3Area of stationary object
If the display screen size is increased to show more information, then information completeness improves, but the device size and weight increase
Solution Approach 1:
The display transitions from a traditional flat 2D surface to a curved 3D surface that wraps around the housing. This dimensional change allows the display to utilize the curved surface area of the housing, effectively increasing the display area without increasing the overall device volume. The curved display fits within the existing device contours.

AI summary
An electromechanical handheld surgical device includes a housing, and a non-planar display screen. The housing encloses a processor, a memory storing instructions, and an orientation detector configured to detect orientation of the electromechanical handheld surgical device with respect to a reference direction. The non-planar display screen is fixedly attached around a portion of the housing and configured to display information. Then instructions, when executed by the processor, cause the non-planar display screen to display the information on a portion of the non-planar display screen. The portion of the non-planar display screen is determined by the processor based on the detected orientation.
