Adaptive Screen Transition Rules for Small Display Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with small display units face challenges in allowing users to easily and rapidly find desired functions due to limited screen space and complex hierarchical structures, making it difficult for both knowledgeable and novice users to navigate.
Innovation Solution
A display device with a storage unit, designation unit, and display controller that employs specific screen transition rules to facilitate easy navigation by transitioning between screens based on user inputs, including rules for hierarchical structures and sequential display of all screens, eliminating the need for a separate operation unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hierarchical structure with multiple layers is used to organize functions in a small display unit, then the device can accommodate more functions, but it becomes difficult for users to rapidly find desired items
Solution Approach 1:
The patent applies dynamics by making the screen transition rules selectable and changeable based on user needs. The system allows switching between hierarchical transition rules (for knowledgeable users) and linear transition rules (for rapid browsing), making the navigation structure adaptive rather than fixed. This resolves the contradiction by allowing the display to accommodate multiple functions through hierarchical organization while enabling rapid access through selectable linear navigation when needed.
Solution Approach 2:
The patent changes the parameter of screen transition behavior from a fixed hierarchical structure to a selectable variable. By allowing users to choose between different transition rules (hierarchical vs. linear), the system adjusts the navigation parameter based on user knowledge level and task requirements, thereby maintaining both comprehensive function coverage and ease of finding desired items.
2Length of moving object
If the display unit size is reduced for portability, then the device becomes more portable, but the resolution and amount of information displayed decreases
Solution Approach 1:
The patent applies segmentation by organizing functions into multiple hierarchical layers, where each layer presents a manageable subset of functions. This allows comprehensive functionality to be distributed across segments (layers) that can be navigated systematically, compensating for the limited display area of small portable devices while maintaining portability.
3Adaptability or versatility
If multiple screen transition rules are provided for different user needs, then the system becomes more adaptable to different users, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a single navigation system that can operate under multiple transition rules. Rather than creating separate systems for different user types, the universal navigation interface supports both hierarchical and linear transition rules, allowing one system to serve multiple user needs and knowledge levels without increasing overall device complexity.

AI summary
A display device includes a storage storing a plurality of rules including first and second rules, a designator that designates one rule of the plurality of rules, and a controller that causes a screen to transition from one screen to another screen in accordance with the one rule. The first rule includes a rule that causes a screen to transition from a first screen to a second screen in response to a user's first action, and a rule that causes a screen to transition from the first screen to a third screen in response to a user's second action. The second rule includes a rule that causes a screen to transition from the first screen to the second screen in response to a user's third action, and a rule that causes a screen to transition from the second screen to the third screen in response to the user's third action.
