Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices face challenges in providing a secure and efficient input reception system, often requiring redundant detection systems and limited resolution on resistive touchscreens, which increases component and development costs.
Innovation Solution
A medical device with an input unit that receives user input and a feedback unit that provides immediate haptic, acoustic, or optical feedback, eliminating the need for redundant detection systems and allowing for customizable feedback based on input type and user preference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a resistive touchscreen is used to receive user input, then the device can capture user inputs, but the resolution for defining input areas is limited and multiple displays must be switched between
Solution Approach 1:
The touchscreen is divided into multiple input zones or regions, each capable of receiving different types of inputs. This segmentation allows the single display to provide multiple functions without requiring switching between multiple displays, thereby improving input area resolution while maintaining device simplicity.
2Reliability
If a redundant or diverse capture system is used to ensure high reliability for receiving inputs, then input reception reliability is improved, but the demand for components and software increases
Solution Approach 1:
A feedback mechanism is implemented that provides immediate confirmation to the user when an input is successfully received and processed. This feedback loop ensures high reliability of input reception without requiring redundant capture systems, as the feedback confirmation eliminates the need for multiple backup input detection mechanisms.
3Reliability
If no feedback is provided to confirm input reception, then the device operation is simpler, but user security and confirmation of input are reduced
Solution Approach 1:
The system implements a feedback mechanism that provides immediate confirmation to the user when an input is successfully received. This feedback ensures high user security and input confirmation while maintaining relatively simple device architecture, as the feedback uses existing display and processing components rather than adding complex separate systems.
