Watch Display Layout to Reduce Capacitive Field Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic watches with capacitive or inductive pointing devices face interference issues due to the proximity of display needles, leading to increased electrical consumption and reduced autonomy.
Innovation Solution
A display system with a movable element, such as a needle, is positioned above the display device and partially overlaps it, creating an area where the user can interact without disturbing the capacitive or inductive field, thereby reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable element (needle) is positioned close to the display device to enable information pointing, then the user can interact with the display, but the needle interferes with the capacitive or inductive field, causing increased energy consumption
Solution Approach 1:
The patent positions the movable element in a third dimension (above the display device) rather than within the planar overlap area, allowing the needle to be physically separated from the capacitive/inductive field while maintaining visual alignment with the display for user interaction
Solution Approach 2:
The movable element is extracted from the overlap area between the display and pointing device, removing it from the region that generates capacitive or inductive fields, thereby eliminating the interference and associated energy consumption increase
2Use of energy by moving object
If the movable element is excluded from the overlap zone to reduce interference, then energy consumption decreases, but the display area covered by the movable element is reduced
Solution Approach 1:
The movable element is positioned above the display device in the vertical dimension, allowing it to be excluded from the horizontal overlap zone while still maintaining visual alignment and functional coverage of the display area
