Portable Message Search Interface With Expandable Criteria Fields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing message search functionalities on portable devices with limited display space and touch-sensitive interfaces are cumbersome, making it difficult for users to specify and input search criteria efficiently.
Innovation Solution
A method and apparatus for searching a message store on a portable device, which includes displaying a search input box, generating and displaying multiple possible search criteria, allowing users to select and add these criteria to a search string, and using a touch-sensitive display for input and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple input fields for search criteria are displayed on the screen, then users can input comprehensive search criteria, but the display space is consumed and the interface becomes complex
Solution Approach 1:
The search criteria are segmented into two parts: a compact display area showing only essential fields, and a hidden/expandable area containing all available fields. This allows the interface to maintain simplicity on the screen while preserving comprehensive search capability through expansion mechanisms.
Solution Approach 2:
The interface transitions from a two-dimensional screen display to a multi-dimensional interaction model by adding drop-down menus, expandable fields, and contextual menus that provide additional search criteria on demand, effectively adding a third dimension to the limited display space.
2Adaptability or versatility
If multiple input fields are displayed on the screen, then users can access all search criteria, but the ease of operation decreases due to the need to switch between fields
Solution Approach 1:
The system pre-configures default search fields and provides intelligent defaults for search criteria. Common search terms are automatically suggested and fields are pre-filled where appropriate, reducing the need for users to manually navigate and configure multiple input fields.
Solution Approach 2:
The search interface provides automatic field detection and suggestion based on user input patterns. The system self-adjusts which fields are displayed and in what order, reducing manual navigation effort by adapting the interface to user needs in real-time.
3Ease of operation
If a unified search interface is provided for all message types, then search functionality is simplified, but the ability to specify precise search criteria is reduced
Solution Approach 1:
The search interface dynamically adapts its complexity based on the search context. For simple searches, the interface remains unified and straightforward. For more complex searches, the interface automatically expands to provide advanced filtering options and precise criteria specification, maintaining simplicity when needed while providing precision when required.
Solution Approach 2:
The search interface is designed as a universal multi-functional component that can handle both simple and complex search requirements. It provides a unified entry point for all search types while internally adapting to provide the appropriate level of specificity through contextual menus and dynamic field display.
