Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of balancing the need for larger displays in portable electronic devices to accommodate multimedia services while maintaining a compact form factor has not been adequately addressed, compromising the devices' portability and usability.
Innovation Solution
The electronic device incorporates a housing design with a first and second housing that allows for a slide mechanism, utilizing a driving element with a shaft, arm, elastic, and link structures to extend a portion of the display, enabling a sliding motion that expands the display area without increasing device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a larger display is used to accommodate multimedia services, then the display area is improved, but the device size increases compromising portability
Solution Approach 1:
The patent implements a sliding mechanism where the first housing can move relative to the second housing, allowing the display area to dynamically change from a compact state to an extended state. This dynamic structure enables the device to adapt its display area based on usage needs without permanently increasing its base size.
Solution Approach 2:
The patent utilizes a sliding motion along the longitudinal axis to extend the display area. By moving the first housing in one dimension (length), the effective display area increases without requiring an increase in all three dimensions, thus maintaining a compact form factor when the display is not extended.
2Area of stationary object
If a sliding mechanism is added to extend display area, then the display area is improved, but the device complexity increases
Solution Approach 1:
The first housing is nested within or alongside the second housing, with both housings containing multiple internal components (driving element, elastic structure, link structure). This nesting arrangement allows the sliding mechanism to be integrated within the existing device form factor without requiring external additions that would increase overall complexity.
Solution Approach 2:
The elastic structure automatically provides the force needed to move the first housing during sliding operations. This self-service mechanism reduces the need for complex motorized systems, sensors, and control circuits, thereby simplifying the overall device complexity while still achieving the desired display extension functionality.
3Adaptability or versatility
If a driving element with multiple structures is used to enable sliding, then the display extendability is improved, but the device complexity increases
Solution Approach 1:
The driving element combines multiple functional structures (shaft, arm, elastic structure, link structure) into a single integrated mechanism. Rather than using separate components for each function, these structures are merged to work together as one cohesive system, reducing the number of independent parts and simplifying the overall driving element complexity.
Solution Approach 2:
The driving element is designed to perform multiple functions: the shaft provides rotational motion, the arm converts rotation to linear motion, the elastic structure provides force and returns the mechanism to its initial position, and the link structure connects and coordinates the movements. This multi-functional design allows a single driving element to achieve display extension, maintain compactness, and enable smooth sliding operations without requiring multiple separate mechanisms.
