Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high mistaken touch rate of virtual buttons on curved screens in electronic devices leads to accidental device shutdowns.
Innovation Solution
Incorporating a physical button with a pressure sensor and trigger assembly into the electronic device, where the curved screen's curved portion drives the trigger assembly to contact the pressure sensor upon a target pressing operation, triggering the button's function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If virtual buttons are used on the curved screen to expand display area, then the screen area can occupy the side edges and extend to the back, but the mistaken touch rate increases leading to accidental device shutdowns
Solution Approach 1:
The patent introduces a physical button as an intermediary component between the user and the device functions. This physical button is positioned on the curved screen's side edge and provides tactile feedback, allowing users to distinguish between accidental touches and intentional operations. The physical button mechanism includes a pressing area that triggers specific functions, serving as a mediator that resolves the contradiction between maximizing screen area and preventing mistaken touches.
2Area of stationary object
If virtual buttons are used on the curved screen, then the screen area is maximized, but the operation accuracy decreases due to high mistaken touch rate
Solution Approach 1:
The patent applies local quality by creating a distinct physical button region on the curved screen with different tactile properties from the rest of the screen surface. The physical button has a specific pressing area with defined mechanical characteristics (spring force, travel distance, tactile feedback) that differ from the flat touchscreen surface. This localized differentiation allows users to easily identify and operate the button accurately while maintaining the overall curved screen design for maximum display area.
3Reliability
If the curved portion extends toward the accommodating cavity to enable physical button function, then the mistaken touch rate is reduced, but the device structure becomes more complex
Solution Approach 1:
The patent merges the physical button structure with the curved screen assembly by positioning the button's pressing area on the curved portion that extends toward the accommodating cavity. The button mechanism is integrated into the existing device architecture, where the curved screen's structural elements serve dual purposes: maintaining display functionality and providing the physical button's mechanical structure. This merging approach reduces the need for separate, complex button assemblies while achieving reliable physical button operation.

Function Achieved in This Case
Reduces the mistaken touch rate by providing a reliable physical button activation mechanism, enhancing user interaction accuracy and device functionality.
Implementation Method 1
the first button includes a pressure sensor and a trigger assembly, the pressure sensor is disposed in the accommodating cavity, the trigger assembly is disposed at the second end of the curved portion, and the trigger assembly and the pressure sensor are disposed at an interval, where in a case that the curved portion receives a target pressing operation, the second end of the curved portion drives the trigger assembly to contact the pressure sensor, thereby triggering the pressure sensor

AI summary
An electronic device is provided. The electronic device includes a curved screen, a housing that matches the curved screen to form an accommodating cavity, and a first button. The curved screen includes a plane portion and a curved portion. A first end of the curved portion is connected to the plane portion. The curved portion bends and extends toward the housing. A second end of the curved portion extends toward the accommodating cavity. The first button includes a pressure sensor and a trigger assembly. The pressure sensor is disposed in the accommodating cavity, the trigger assembly is disposed at the second end of the curved portion, and the trigger assembly and the pressure sensor are disposed at an interval. In a case that the curved portion receives a target pressing operation, the second end of the curved portion drives the trigger assembly to contact and trigger the pressure sensor.
