Remote Controller Screen Rotation for Accessible Display Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote controllers for devices like air conditioners and lighting systems are difficult for advanced senior citizens and users with poor vision to operate due to fixed display sizes, requiring dedicated switches for magnification, which complicates the user experience.
Innovation Solution
A remote controller with a rotational state detector and display controller that allows users to switch between display modes by rotating the device, selecting from predetermined modes based on user tiers without needing to operate specific switches, enabling a desired display mode for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display size is fixed at a standard size for general users, then the remote controller is easy to manufacture and operate for most users, but the display content becomes difficult to recognize for advanced senior citizens and users with poor vision
Solution Approach 1:
The patent applies the dynamics principle by making the display size adjustable rather than fixed. The display controller dynamically changes the display size based on detected rotational states, allowing the same display device to adapt between standard size for general users and magnified size for users with poor vision, thus resolving the contradiction between ease of operation and recognizability
Solution Approach 2:
The patent employs parameter changes by varying the display size parameter in response to rotational state changes. When the remote controller is rotated to specific angles, the display controller changes the display size parameter to provide magnified content, enabling users with poor vision to recognize display content while maintaining standard operation for other users
2Loss of information
If a dedicated magnification switch is added to enable magnified display, then users with poor vision can recognize display content better, but the device complexity and operational difficulty increase for all users
Solution Approach 1:
The patent applies universality by making the rotational operation serve multiple functions. The rotation operation not only switches display modes but also can be used for other control functions, eliminating the need for a dedicated magnification switch. This reduces device complexity while maintaining the ability to provide magnified display for users with poor vision
Solution Approach 2:
The patent merges the magnification function with the existing rotational operation. Instead of adding a separate dedicated switch for magnification, the patent combines the display size adjustment function with the rotational switching operation, allowing users to access magnified display through the same rotational mechanism used for other controls, thus reducing device complexity
3Loss of information
If a dedicated magnification switch is added to enable magnified display, then users with poor vision can recognize display content better, but the ease of operation decreases for users unskillful in remote controller operations
Solution Approach 1:
The patent applies self-service by enabling users to automatically switch between display modes through simple rotational gestures. Users with poor vision can naturally rotate the remote controller to access magnified display without needing to learn or remember which specific switch to press, making the system self-adapting to user needs and greatly improving ease of operation

AI summary
A remote controller includes a user interface, a rotational state detector, and a controller. The rotational state detector detects a rotational state of the remote controller. The controller, based on the rotational state detected by the rotational state detector, selects a display mode from among a plurality of display modes depending on different user tiers. Then the controller causes the user interface to display an operation screen in the selected display mode.
