Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of mobile phone menus due to integrated functions limits user usability, as users face difficulty in executing specific functions like audio playback, which requires navigating through hierarchical menus.
Innovation Solution
A mobile terminal with an orientation detection unit, retrieval unit, key arrangement configuration unit, and control unit that switches operation modes based on the device's orientation, reconfiguring key arrangements and screen displays to facilitate easier access to functions like multimedia or communication modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hierarchical menus are used to integrate multiple functions, then function integration is improved, but key manipulation complexity increases
Solution Approach 1:
The patent applies dynamics by making the key arrangement configurable and changeable based on operation mode. The key arrangement configuration unit reconfigures key mappings dynamically when switching between communication mode and multimedia mode, allowing the same physical keys to serve different functions in different contexts, thus reducing manipulation complexity while maintaining function integration
Solution Approach 2:
The patent changes the parameter of key arrangement configuration based on operation mode. When the mobile terminal detects a mode switch (e.g., from communication to multimedia), it automatically adjusts the key mapping parameters, enabling different key sequences to trigger different commands appropriate for each mode, thereby simplifying user interaction without sacrificing functional versatility
2Adaptability or versatility
If more functions are integrated into mobile phone, then adaptability is improved, but menu depth increases
Solution Approach 1:
The patent segments the operational context into distinct modes (communication mode and multimedia mode). By dividing the operational space into mode segments, the system can present simplified mode-specific interfaces and key arrangements for each segment, rather than requiring users to navigate through deep hierarchical menus that combine all functions in a single structure
Solution Approach 2:
The patent implements universality by enabling the same physical key arrangement to serve multiple functions through mode-dependent configuration. The key arrangement configuration unit allows a single set of physical keys to execute different commands based on the current operation mode, eliminating the need for separate physical interfaces for different function sets and reducing overall system complexity
