Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch panels in medical devices face challenges with feedback confirmation during operations, particularly due to protective barriers and gloved hands, leading to potential erroneous operations without clear tactile or auditory feedback.
Innovation Solution
A touch panel design incorporating a suspended component with a touch screen, a fixed component, an elastic element, and a vibration generating component that allows relative movement and vibration feedback, utilizing electromagnetic forces or mechanical mechanisms to provide tactile feedback, and includes a point-contact silicone rubber pad and sealing foam for reduced friction and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective bag is used to protect the touch panel during surgery, then the touch panel is protected from contamination, but the doctor experiences difficulty in operating the touch panel due to double isolation with gloves
Solution Approach 1:
The patent introduces vibration feedback through a vibration generating component that provides tactile confirmation when the touch panel is touched. This feedback mechanism allows the doctor to confirm touch operations through vibration sensation despite wearing gloves and a protective bag, resolving the operation difficulty while maintaining protection.
2Reliability
If a protective bag is used to protect the touch panel, then contamination is prevented, but tactile feedback for confirming touch operations is lost
Solution Approach 1:
The vibration generating component provides tactile feedback through vibration sensation that can be perceived through gloves and the protective bag. This feedback mechanism enables the doctor to detect and confirm touch operations despite the protective barriers, solving the touch confirmation difficulty.
3Area of stationary object
If the touch panel is made large and heavy to provide better display, then display quality is improved, but vibration feedback becomes unreliable
Solution Approach 1:
The patent introduces a counterweight component that balances the weight of the large, heavy touch panel. This counterweight enables the vibration generating component to effectively drive the suspended component to vibrate despite the panel's weight, ensuring reliable vibration feedback while maintaining the large display size.
Solution Approach 2:
The patent employs a suspended component structure that can dynamically move relative to the fixed component. This dynamic structure allows the vibration feedback mechanism to function effectively on large, heavy touch panels by creating controlled vibrations through the interaction between the vibration generating component and the elastic element.
4Ease of operation
If the suspended component is allowed to move relative to the fixed component for vibration feedback, then tactile feedback is achieved, but friction and noise increase
Solution Approach 1:
The patent introduces a sliding mounting member as an intermediary component between the fixed component and the suspended component. This sliding mounting member reduces friction during relative movement and includes a point-contact silicone rubber pad that minimizes noise generation while enabling the vibration feedback function.
