Solution Overview
Problem
Portable electronic devices with capacitive touch displays face challenges in accurately selecting function icons due to small display sizes and the need for additional magnification, leading to operational inefficiencies and potential errors, especially when using a finger as the operating object.
Innovation Solution
A display apparatus incorporating an antenna module that establishes electromagnetic induction spaces to detect the position of an object, allowing users to move an indicator on the display to select function icons without physical contact, using a control circuit to generate signals for selecting and activating desired functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a capacitive touch display is used with small display size, then the portable electronic device can be compact, but the user may touch the wrong icon due to small function icons and unstable indication
Solution Approach 1:
The patent introduces an electromagnetic induction field as an intermediary between the user's object and the display. This field enables non-contact detection of the object's position, providing stable indication without requiring the user to physically touch the small display area, thus resolving the contradiction between compact size and selection accuracy
Solution Approach 2:
The patent replaces the mechanical touch-based selection system with an electromagnetic induction-based system. Instead of relying on physical contact or visual magnification, the system uses electromagnetic fields to detect object position and enable icon selection, maintaining compact size while improving selection precision
2Measurement precision
If local image magnifying function is enabled to improve icon selection accuracy, then the user can select functions more accurately, but the operational efficiency decreases and normal presentation of other images is interfered with
Solution Approach 1:
The patent replaces the visual magnification mechanism with an electromagnetic induction-based position detection system. This allows accurate icon selection without altering the display content or requiring magnification, thus maintaining operational efficiency while improving selection accuracy
Solution Approach 2:
The electromagnetic induction field serves as an intermediary that provides precise position detection without interfering with the normal display presentation. Users can select icons accurately while the full display content remains visible and accessible, avoiding the need for magnification that would reduce operational efficiency
3Measurement precision
If local image magnifying function is used to improve icon selection accuracy, then selection precision improves, but the device complexity increases due to additional software functions
Solution Approach 1:
The patent replaces complex software-based magnification functions with a hardware-based electromagnetic induction system. This physical field-based approach provides accurate position detection through antenna modules and control circuits, reducing software complexity while maintaining or improving selection precision
