Multi-Function Input Component for Compact Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cellphones face challenges with insufficient input components to accommodate increasing functions due to limited space, leading to complex and troublesome operations.
Innovation Solution
The design of an input component with a first area performing a primary function and a second area providing additional functions when pressed simultaneously, allowing for multiple operational modes and reducing the need for additional keys by utilizing a mechanical or capacitance key structure with defined areas and sub-areas, and software-set ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more keys are added to the cellphone to accommodate increasing functions, then the functionality is improved, but the device size increases and space becomes insufficient
Solution Approach 1:
The patent applies multi-functionality by enabling a single key to perform multiple functions through different operation modes. The key can function as a standard key, a hot key for quick access, or a dual-function key combining both modes, allowing one physical component to replace what would traditionally require multiple keys, thus maintaining functionality while reducing device size
Solution Approach 2:
The patent segments the key's operational capabilities into distinct modes (standard key mode and hot key mode) that can be selectively activated. This segmentation allows the system to provide different functions through the same physical key by changing its operational state, effectively multiplying the functionality available from limited physical components
2Area of stationary object
If the amount of keys is kept the same to maintain device size, then the device remains compact, but the operation becomes complex and troublesome to meet increasing functions
Solution Approach 1:
The patent implements preliminary action by pre-configuring hot keys that provide immediate access to frequently used functions without requiring multiple navigation steps. Users can quickly access desired functions through the hot key feature, reducing the complexity and number of operations needed compared to traditional key navigation through menus and sub-menus
3Adaptability or versatility
If more functions are introduced into the cellphone, then the adaptability is improved, but the operational complexity increases due to insufficient keys
Solution Approach 1:
The patent resolves this contradiction by making keys universal through multi-functionality. Each key can adapt to perform different functions based on its mode setting, allowing the system to accommodate more functions without proportionally increasing the number of keys or the complexity of operation. The same physical key serves multiple purposes across different operational contexts
