Foldable Input Module Linkage for Flat Storage and Tracking Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable input devices, such as wireless mice, often have a permanently protruding section that compromises portability and aesthetics due to housing components, leading to non-uniform device configurations.
Innovation Solution
A foldable input device with linkage mechanisms that move a module between recessed and protruding positions, allowing a uniform flat configuration for portability and an angled configuration for improved optical tracking accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a permanently protruding section is used to house components, then component housing is achieved, but portability and aesthetics are compromised due to non-uniform device configuration
Solution Approach 1:
The patent applies the dynamics principle by making the module housing dynamic rather than static. The module can transition between a protruding position (when needed for component access or manufacturing) and a recessed position (for uniform device configuration). This is achieved through a movable connection mechanism between the module and device body, allowing the housing to adapt its position based on operational requirements, thus resolving the contradiction between ease of manufacture and device uniformity.
2Measurement precision
If the optical module is positioned at a favorable angle for tracking accuracy, then tracking precision is improved, but the device cannot maintain a uniform flat configuration
Solution Approach 1:
The patent implements dynamics by enabling the optical module to change its angular position dynamically. The module can be oriented at a favorable angle relative to the device body when tracking accuracy is prioritized, and can be repositioned to maintain a flat configuration when portability is needed. The movable connection mechanism facilitates this angular adjustment, allowing the system to optimize tracking precision without permanently compromising the device's flat profile.
3Shape
If the module is recessed in the flat orientation, then portability is enhanced, but optical tracking accuracy may be compromised without proper angular positioning
Solution Approach 1:
The patent resolves this contradiction through dynamic positioning capability. The module can be recessed into the device body for a flat, portable configuration, and can be extended or angled outward when tracking accuracy is required. The movable connection mechanism enables this dynamic transition, ensuring that portability and tracking accuracy are not mutually exclusive but can be optimized based on operational context.

AI summary
Examples are disclosed that relate to an input device foldable between a flat orientation in which both ends of a module comprising a sensor are within the input device and a curved orientation in which one end of the module protrudes. A head portion comprises a recess containing the module. A foldable tail portion is coupled to the head portion. A slidable frame comprises an anchor portion affixed to the foldable tail portion and a connecting portion configured to slide relative to the tail portion. A linkage is affixed to the slidable frame and configured to engage and move the module relative to the head portion upon sliding of the slidable frame.
