Hinged Sub-Display Chassis Structure for Closed-State Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with a sub-display configuration are limited to use when the main display is open, preventing the sub-display from functioning when the chassis is closed.
Innovation Solution
A protruding portion on the first chassis supports a sub-display, connected via a hinge device with rotatable hinge shafts and arms, allowing the sub-display to remain exposed and functional regardless of the rotation angle between the chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sub-display is installed on the rear surface of the second chassis, then the sub-display can be used when the chassis is closed, but the sub-display cannot be substantially used when the main display is used
Solution Approach 1:
The patent applies the dynamics principle by making the sub-display rotatable relative to the second chassis through a hinge mechanism. This allows the sub-display to dynamically adjust its position and orientation based on whether the chassis is closed or open, enabling it to be viewed from appropriate directions in both states without being fixed in a single location
2Ease of operation
If the sub-display is installed on the first chassis, then the sub-display can be used when the main display is used, but the sub-display cannot be used when the chassis is closed
Solution Approach 1:
The hinge mechanism enables the sub-display to dynamically reposition itself. When the chassis is closed, the sub-display can rotate to face outward for visibility; when the chassis is open, it can adjust to face the user appropriately. This dynamic adaptability resolves the contradiction between usability in open and closed states
3Adaptability or versatility
If the sub-display is mounted on the protruding portion, then the sub-display can be used regardless of rotation angle, but the device complexity increases
Solution Approach 1:
The hinge device is segmented into multiple independent components: hinge shafts, hinge arms, and connection portions. This segmentation allows each component to perform a specific function (rotation support, structural connection, positioning) while keeping the overall design manageable and maintainable despite the increased complexity required for multi-angle usability

AI summary
An electronic apparatus includes: a first chassis; a second chassis that is mounted with a display; and a hinge device that relatively rotatably connects one edge portions of the first chassis and the second chassis to each other. A protruding portion in which a portion except for both side portions in a longitudinal direction protrudes toward a rear side is provided in the one edge portion of the first chassis. The hinge device includes a pair of hinge shafts that are connected to both end surfaces of the protruding portion in the longitudinal direction, and relatively rotatably connect the protruding portion and the second chassis, and a pair of hinge arms that integrally fix each of the pair of hinge shafts and the one edge portion of the second chassis.
