Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartwatches with integrated touch displays face issues due to their small size, causing display areas to be easily blocked by fingers during operations, leading to unlocking errors and potential privacy exposure when no lock is set.
Innovation Solution
An electronic device with a housing and a rotating bezel that adjusts electrical signals between conductive layers, allowing intuitive operation by monitoring connection states and electrical signals to perform functions without obstructing the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch display is used for direct finger operation, then ease of operation is improved, but the display area is easily blocked by the finger causing operation errors
Solution Approach 1:
The patent introduces a bezel as an intermediary component between the user and the touch display. The bezel includes a first conductive layer that can be operated to generate electrical signals, which are then transmitted to the processor. This mediator allows user interaction without requiring direct finger contact with the display area, thus preventing display blocking while maintaining operational ease.
Solution Approach 2:
The patent replaces direct mechanical touch interaction on the display surface with an electrical signal generation mechanism on the bezel. The first conductive layer on the bezel generates electrical signals through user operation (such as rotation or pressing), which are then processed by the processor to control the display. This substitution eliminates the need for finger contact with the display area while preserving intuitive operation.
2Area of stationary object
If the display area is made small to fit smartwatch form factor, then device compactness is improved, but the display is easily blocked by finger during operation
Solution Approach 1:
The bezel serves as an intermediary input device that extends the operational interface beyond the limited display area. Users can interact with the bezel's conductive layer through rotation or pressing actions, providing adequate input capability without requiring a larger display area. This resolves the conflict between compactness and operational convenience.
3Ease of operation
If no lock is set for the screen to improve accessibility, then ease of operation is improved, but user privacy is easily exposed
Solution Approach 1:
The patent implements a feedback mechanism where the processor monitors electrical signals from the first conductive layer on the bezel and the second conductive layer on the display. Based on the detected signal patterns (such as specific rotation directions or pressing sequences), the processor automatically adjusts the lock state of the display. This allows the system to provide easy access when appropriate while automatically enforcing privacy protection when needed, without requiring manual lock configuration by the user.
