Rotating Display Mechanism for Dual-State Mobile Phone Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable communication devices with hinged covers and dual displays face issues of increased weight, manufacturing costs, and high power consumption due to the need for two separate displays and input mechanisms.
Innovation Solution
A portable communication device with a rotating display that pivots within a dedicated opening, allowing a single screen to function as both a front and back display, reducing weight, cost, and power consumption by eliminating the need for two separate displays and input sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional mobile phone is designed with both front display and back display on the hinged cover, then the user can operate the mobile phone whether the cover is closed or open, but the weight of the mobile phone increases
Solution Approach 1:
The patent merges the front display and back display into a single display unit that can rotate between two positions. When the cover is closed, the display shows information for the user; when the cover is open, the display rotates to show information facing the phone body. This combining of two separate displays into one rotating display reduces the overall weight of the mobile phone while maintaining the ability to provide display functionality in both closed and open states.
Solution Approach 2:
The patent introduces a rotating mechanism that allows the display to change its orientation dynamically. The display can rotate between a first position (facing the user when cover is closed) and a second position (facing the phone body when cover is open). This dynamic repositioning capability eliminates the need for separate fixed displays for both states, thereby reducing weight while preserving adaptability.
2Adaptability or versatility
If a conventional mobile phone is designed with both front display and back display on the hinged cover, then the user can operate the mobile phone whether the cover is closed or open, but the manufacturing cost increases
Solution Approach 1:
The patent combines two separate display components into a single rotating display unit. This merging reduces the number of parts that need to be manufactured, assembled, and quality-checked, thereby lowering manufacturing costs. The single display unit is mounted on a rotating mechanism that allows it to serve dual purposes in different cover states, eliminating the need for duplicate display hardware.
Solution Approach 2:
The rotating display serves multiple functions: it acts as the front display when the cover is closed and as the back display when the cover is open. This multi-functionality eliminates the need for separate dedicated displays for each state, reducing component count and simplifying the manufacturing process while maintaining full operational capability.
3Adaptability or versatility
If a conventional mobile phone is designed with both front display and back display on the hinged cover, then the user can operate the mobile phone whether the cover is closed or open, but the power consumption increases
Solution Approach 1:
The patent merges two separate display power consumption sources into a single rotating display unit. Only one display needs to be powered at any given time, regardless of whether the cover is closed or open. This eliminates the cumulative power consumption of two separate displays while maintaining the ability to provide display functionality in both states.
Solution Approach 2:
The rotating display mechanism allows a single display unit to dynamically replace the function of two static displays. By rotating to the appropriate position based on cover state, the system maintains operational versatility while consuming less power, as only one display unit requires power supply regardless of operational mode.
4Adaptability or versatility
If a conventional mobile phone is designed with both front display and back display on the hinged cover, then the user can operate the mobile phone whether the cover is closed or open, but the device complexity increases
Solution Approach 1:
The patent combines two separate display assemblies into a single rotating display unit. This merging reduces the number of components, mounting structures, and control circuits required, thereby simplifying the overall device architecture while maintaining the capability to function in both closed and open cover states.
Solution Approach 2:
The rotating display unit serves as both the front display and back display, eliminating the need for separate display assemblies. This multi-functionality reduces structural complexity by using a single universal display component that adapts to different operational states through rotation, rather than requiring dedicated hardware for each state.

AI summary
The present invention is to provide a portable communication device with a rotating display, which comprises a phone body and a cover hingedly connected to the phone body. Thus, the cover may pivot about the phone body either in one direction to close onto the phone body or in the other opposite direction to open from the phone body. The cover comprises an opening for receiving a display having a first pivotal element provided at either side of the display and a second pivotal element provided at either side of the opening. The first pivotal element is connected to the second pivotal element at the same side and is adapted to turn relative thereto to form a pivot such that rotating the display in the opening on the opposite pivots will appropriately dispose either the screen of the display facing the phone body or in a direction opposing the phone body.
