Foldable Hinge Pause Mechanism for Accurate Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with a flat-type design, the continuous closing movement of the lid cover section without resistance makes it difficult to capture the imaging timing accurately when photographing subjects, such as business cards or memos, due to the lack of control over the tilt angle of the lid cover section.
Innovation Solution
An electronic device design featuring a first flat section on the back surface, a second flat section that openably and closably covers the front surface, and a coupling section that allows the second flat section to be folded and paused at a predetermined angle, ensuring accurate imaging timing by utilizing a pause section with a first hinge that rotates with a predetermined force and a second hinge that rotates with less force, along with a click-feeling providing section to confirm the tilt angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid cover section performs continuous closing movement without resistance, then the closing operation is smooth and easy, but the imaging timing cannot be accurately captured when the lid is tilted at a predetermined angle
Solution Approach 1:
The closing movement is divided into distinct phases: a first closing phase where the lid moves smoothly, and a second closing phase where the pause section creates a temporary halt at the predetermined tilt angle. This periodic action pattern allows the imaging section to capture images at the paused position while maintaining smooth operation during the non-paused portions of the closing movement.
Solution Approach 2:
The pause section applies a preliminary counteracting force to the closing movement before the lid reaches the fully closed position. This counter force temporarily halts the closing action at the predetermined tilt angle, creating a stable imaging position. The pause section then releases this counter force to allow the closing movement to resume, thus preventing the imaging timing accuracy problem while preserving overall operational smoothness.
2Measurement precision
If the lid cover section is tilted at a predetermined angle for imaging, then accurate imaging can be achieved, but the closing movement becomes interrupted and resistant
Solution Approach 1:
The closing operation follows a periodic pattern with distinct phases: smooth closing movement during the first phase, and a temporary paused state during the second phase when imaging occurs. This periodic structure ensures that the interruption and resistance are localized to specific moments rather than affecting the entire closing operation, thereby maintaining overall ease of operation while achieving accurate imaging timing.
Solution Approach 2:
The pause section provides preliminary counter resistance only when the lid approaches the predetermined tilt angle needed for imaging. This targeted anti-action creates the necessary pause for accurate imaging without preventing the lid from being tilted to the required angle. The counter force is applied temporarily and then released, allowing the closing movement to resume smoothly afterward.
