Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses for forming large screens are not easily adaptable for folding and unfolding, making them inconvenient for installation and use in various settings, such as households and public places, where they need to harmonize with surroundings when folded and provide a seamless display when unfolded.
Innovation Solution
A modular display apparatus with multiple display modules arranged vertically, using hinges and electromagnets for easy coupling and decoupling, allowing the modules to switch between a folded and unfolded state, with a controller managing the magnetic forces to attach or detach the modules for power supply and image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If display modules are fixed rigidly to form a large screen, then the screen stability is improved, but the adaptability for folding and unfolding deteriorates
Solution Approach 1:
The display apparatus is divided into multiple independent display modules that can be separately coupled and decoupled. Each module contains its own display panel and control circuitry, allowing the system to be configured in different states (folded/unfolded) by adjusting the coupling of modules through hinges and magnetic coupling guides, thus achieving both stability when assembled and adaptability for reconfiguration.
Solution Approach 2:
The display modules are connected through hinges that enable rotational movement, transforming the rigid fixed structure into a dynamic system. The hinges allow modules to swing between coupled (unfolded) and decoupled (folded) positions, while magnetic coupling guides provide stable attachment when coupled and easy separation when needed, achieving dynamic adaptability between different operational states.
2Stability of the object's composition
If display modules are coupled tightly to form a seamless screen, then the display continuity is improved, but the ease of decoupling and folding deteriorates
Solution Approach 1:
The magnetic coupling guides replace traditional mechanical fastening systems (screws, clips, latches) with magnetic fields for coupling and decoupling display modules. The magnets provide strong attractive force to hold modules tightly together for seamless display continuity, while allowing easy separation by overcoming the magnetic force, thus achieving both tight coupling and ease of operation without complex mechanical mechanisms.
3Area of stationary object
If a large number of display modules are used to form a large screen, then the screen size is improved, but the device complexity increases
Solution Approach 1:
The display modules are designed with universal coupling interfaces using standardized hinges and magnetic coupling guides that work identically across all modules. This universality allows any number of modules to be coupled in various configurations (vertical, horizontal, folded, unfolded) using the same coupling mechanism, reducing the complexity of managing multiple different connection types while enabling flexible scaling to large screen sizes.
