Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack efficiency in reducing the time between electronic inputs and do not support simultaneous device interaction for social or work activities, as they require visual attention and physical interaction with standard keyboards.
Innovation Solution
An alternative electronic input system with a compact design that allows tactile input on a device with defined areas for different types of information, enabling quick and automated data entry without visual attention, using a layout that reduces the physical size and allows for touch-based input on various devices like smartphones or headsets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a standard keyboard is used for electronic input, then text entry can be performed, but the time between inputs is excessive and visual attention is required
Solution Approach 1:
The input system is segmented into multiple sensing zones arranged in a circular pattern, allowing users to input different characters by touching different zones. This segmentation enables faster input by eliminating the need to locate specific key positions visually, as each zone corresponds to specific characters or functions.
Solution Approach 2:
The patent transitions from a traditional two-dimensional keyboard layout to a circular arrangement of sensing zones. This dimensional change allows for more efficient finger movement and reduces the distance between commonly used characters, thereby reducing input time and eliminating visual dependency.
2Area of stationary object
If a standard keyboard layout is used, then all necessary keys are available, but the physical size is large and prevents compact design
Solution Approach 1:
Each sensing zone in the circular arrangement is designed to serve multiple functions, with different zones corresponding to different characters, numbers, or commands. This multi-functionality allows the compact circular layout to provide the same input versatility as a full-sized keyboard while occupying minimal space.
Solution Approach 2:
By reorganizing the keyboard layout from a rectangular grid to a circular arrangement, the patent maximizes the use of radial space, allowing all necessary input zones to be accessible within a compact footprint that fits easily on mobile devices.
3Productivity
If visual attention is required for input, then accuracy can be maintained, but simultaneous device interaction for other activities is prevented
Solution Approach 1:
The circular sensing zone layout is designed to be self-explanatory through tactile feedback and spatial memory, allowing users to input text without visual verification. The consistent radial arrangement and tactile differentiation of zones enable users to maintain accuracy through muscle memory and spatial awareness rather than visual attention.
4Area of stationary object
If a compact input design is used, then portability is improved, but the number of definable areas for different information types is reduced
Solution Approach 1:
The sensing zones are designed with multi-functionality, where each zone can represent different characters, numbers, or command types depending on the input mode. This allows the compact circular layout to provide comprehensive information classification capabilities without requiring additional physical space.
Solution Approach 2:
The input system dynamically adapts the function of each sensing zone based on context, allowing the same physical zone to serve different purposes (letters, numbers, symbols) depending on the current input mode or previous inputs, thereby maximizing versatility within a compact form factor.
