Bendable Display Hinge and Rear Operation Member for Compact Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with flexible displays face challenges in reducing device size while increasing display screen size and improving operability, particularly during photography, as the display area becomes smaller at one rotation position and there is a risk of erroneous operation at the other position.
Innovation Solution
An electronic device with a bendable display that includes a hinge part allowing the display to rotate, positioning the operation member on the back surface opposite to the display, enabling both a compact storage state and a large display configuration, thereby maximizing screen size and reducing operational errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display is bent to reduce device size, then portability is improved, but the display area becomes smaller
Solution Approach 1:
The display device transitions from a static to a dynamic configuration through the hinge mechanism, allowing the display to rotate between a bent state (for portability) and an extended state (for maximum display area). This dynamic transformation resolves the contradiction by making the display area variable rather than fixed.
Solution Approach 2:
The invention utilizes rotational movement in a third dimension (angular dimension) to resolve the spatial conflict. By rotating the display around the hinge axis, the device achieves both compact storage (bent configuration) and expanded display area (extended configuration) without compromising either requirement.
2Ease of operation
If the operation unit is positioned on the front surface, then operability is improved, but erroneous operation occurs when user grips the device
Solution Approach 1:
The operation unit is inverted from the conventional front-surface position to the back-surface position. This inversion resolves the contradiction by placing the operation unit on the opposite side of where the user's hand naturally grips the device, eliminating accidental touches while maintaining full operability through the exposed position on the back surface.
3Area of stationary object
If the display is extended to increase screen size, then readability is improved, but device size increases reducing portability
Solution Approach 1:
The display configuration is made dynamic through the hinge mechanism, allowing seamless transition between extended (maximum screen size) and bent (compact device size) states. This resolves the contradiction by making both screen size and device size variable parameters that can be adjusted based on usage context.
Solution Approach 2:
The display structure is segmented into multiple sections connected by the hinge, allowing independent movement of each segment. This segmentation enables the display to be extended for reading and bent for carrying, resolving the contradiction between screen size and device size through modular structural design.

AI summary
A body part of a camera includes a display that is at least partially flexible. A display part of the display includes a first display part and a second display part that are integrally formed. A hinge part that connects the first display part to the second display part to be rotatable relative to each other is provided in the vicinity of a bendable part located at a boundary of each display part. The display is bendable in accordance with rotation of the hinge part with the bendable part as a starting point. An operation member is disposed on a back surface of the second display part, and the operation member is exposed to the outside in a bent state of the display.
