Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deformable slidable electronic devices face challenges in accurately detecting the slid-in and slid-out states due to thickened black matrix areas and fluctuating distances between detection members and flexible displays, leading to reduced detection resolution and potential malfunctions.
Innovation Solution
An electronic device with a bendable conductive member that varies contact with a sensing member during sliding operations, allowing for high-resolution detection of the slid-in and slid-out states without increasing device thickness, using existing components and optimizing mounting space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the black matrix area is thickened to ensure touch sensor detection of the member to be detected, then detection reliability is improved, but device thickness increases and slimming effect is compromised
Solution Approach 1:
A conductive member is introduced as an intermediary component between the touch sensor and the member to be detected. This conductive member has a bent shape that extends from the touch sensor toward the member to be detected, serving as a mediator that enables detection without requiring direct contact or thickening of the black matrix area. The conductive member can be configured as a separate component or integrated into existing structures, allowing the touch sensor to detect the member's position through changes in electrical properties caused by the conductive member's proximity or contact.
2Measurement precision
If the distance between the member to be detected and the flexible display is increased to improve detection accuracy, then measurement precision is improved, but the fluctuation in distance during operation increases and detection resolution is lowered
Solution Approach 1:
The conductive member is designed with a bent shape that is dynamically configured to maintain an substantially equal distance from the member to be detected throughout the sliding operation. The bent structure allows the conductive member to adapt to position changes while preserving a consistent detection gap, preventing distance fluctuation and maintaining high detection resolution during the entire range of motion.
3Ease of manufacture
If existing components are used to build the sensing structure to reduce manufacturing cost, then ease of manufacture is improved, but device complexity increases and mounting space efficiency decreases
Solution Approach 1:
The conductive member is designed to serve multiple functions: it acts as a structural support element, an electrical conductor for the touch sensor, and a positioning reference for the member to be detected. By making the conductive member multi-functional, the sensing structure leverages existing components and structures within the device, avoiding the need for separate dedicated sensing elements and reducing overall device complexity while maintaining manufacturing efficiency.
