Multi-Screen Scaling Control for Remote Controller Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of digital broadcast systems with multiple channels leads to cumbersome remote controllers due to numerous buttons, making it difficult for users to quickly select and scale desired screens.
Innovation Solution
An image processing apparatus with a generation unit for displaying multiple screens on one surface, an operation signal acquisition unit to receive user inputs, and a control unit that scales focused screens, allowing for full-screen display, thumbnail image management, and synchronized scaling of main and sub-display areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated buttons are provided for each screen function, then operational reliability is improved, but device complexity and button count increase
Solution Approach 1:
A single operation button is designed to perform multiple functions depending on the current display state. The button can switch between enlarging main display screens, enlarging sub display screens, and other operations based on context, eliminating the need for separate dedicated buttons for each function while maintaining operational reliability.
2Adaptability or versatility
If multiple dedicated buttons are provided for different screen operations, then functional completeness is improved, but ease of operation deteriorates due to difficulty in quickly finding the desired button
Solution Approach 1:
The function of the operation button dynamically changes based on the current display state. When a main display screen is shown, the button enlarges that screen; when a sub display screen is shown, it enlarges that screen instead. This dynamic adaptation allows users to perform different operations with the same button, improving ease of operation while maintaining functional completeness.
3Adaptability or versatility
If the remote controller includes many buttons for different functions, then adaptability is improved, but the physical size of the remote controller increases
Solution Approach 1:
Instead of providing separate physical buttons for enlarging main screens, sub screens, and other operations, a single operation button is designed to perform all these functions based on the current display context. This significantly reduces the number of physical buttons needed, thereby reducing the overall size of the remote controller while maintaining full functional adaptability.
