Integrated Display Cover for Force Intensity Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for preventing bedsores or massage, such as mats and chairs, often require separate displays to indicate the intensity of external force transmission, which can be inconvenient and difficult to understand, necessitating direct experience to verify the operating mode.
Innovation Solution
A display device integrated with a cover part and a driving unit, featuring a display unit that visually indicates the intensity of external force through light-emitting sections, allowing users to recognize the force intensity directly on the device without additional displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a separate display is used to indicate the intensity of external force, then the user can check the operating mode, but it causes inconvenience and requires additional components
Solution Approach 1:
The display unit is integrated directly into the cover part that contacts the user's body, merging the display function with the existing structural component. This eliminates the need for separate displays while maintaining clear communication of force intensity information to the user.
Solution Approach 2:
The cover part serves as an intermediary element that both transmits external force to the user's body and displays information about the force intensity through an integrated display unit, combining two functions in one component.
2Loss of information
If a separate display is used to indicate the operating mode, then the mode can be displayed, but it is difficult to clearly understand which kind of movement is being transmitted
Solution Approach 1:
Different colors are used to represent different types of movement or operating modes. The display unit changes colors or displays different colored indicators to clearly communicate the specific kind of movement being transmitted, making it immediately recognizable to the user without requiring manual reference.
Solution Approach 2:
Different regions or sections of the display unit may display different information or use different visual characteristics to indicate different movement types, allowing the user to quickly understand the specific operating mode through localized visual cues.
3Measurement precision
If the user directly experiences and feels the external force to check the running mode, then the correct mode can be verified, but it requires direct physical experience which is inconvenient
Solution Approach 1:
The display unit provides immediate visual feedback about the external force intensity and operating mode to the user. This feedback mechanism allows the user to understand the current mode without needing to physically feel or interpret the force, making the system easier to operate while maintaining accurate information about force intensity.
Solution Approach 2:
The mechanical sensing of force intensity by the user's body is replaced with an optical/electronic display system that visually represents the force intensity. This substitution converts physical sensation into visual information, improving user convenience while maintaining measurement precision.
