Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data input devices for electronic devices and portable terminals face challenges in miniaturization, input speed, and usability, particularly in recognizing input selecting positions, especially for languages requiring multiple keys, and in providing a compact yet functional input interface that supports portability and ease of use.
Innovation Solution
A data input device featuring A-B type separation pairs disposed as an array along a separation reference line, with an input reference block containing three A-B type separation pairs arranged as a left-middle-right type, allowing for individual or continuous selection of input positions within the fingerprint region of a fingertip, and a control unit to distinguish between individual and continuous selections, facilitating easy and quick data input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a keyboard type input device is used, then data input capability is provided, but the device size cannot be reduced
Solution Approach 1:
The input device is segmented into a reference block and multiple separation pairs arranged along a reference line. The reference block contains three separation pairs (left, middle, right) that serve as positional anchors, while additional separation pairs are distributed along the reference line. This segmentation allows the input device to maintain comprehensive data input capability while reducing overall size, as each segment serves a specific functional purpose rather than requiring a complete keyboard layout.
Solution Approach 2:
The invention transitions from a two-dimensional keyboard layout to a one-dimensional arrangement along a reference line. Separation pairs are positioned at different locations along this line, with the reference block serving as a central anchor. This dimensional reduction enables significant size miniaturization while preserving input functionality through the strategic arrangement of separation pairs that can represent multiple characters and commands.
2Adaptability or versatility
If multiple input keys are arranged to cover all characters and commands, then complete data input is enabled, but input speed decreases due to slow recognition
Solution Approach 1:
The reference block with its three separation pairs (left, middle, right) is positioned in advance within the fingertip's natural contact area. This preliminary positioning allows users to immediately recognize the structure and begin input without needing to locate keys during the input process. The pre-arranged reference points serve as mental anchors that speed up recognition and reduce the time needed to locate different input positions.
Solution Approach 2:
Different regions of the input device are assigned specific functions: the reference block serves as a positional anchor, separation pairs near the reference block represent frequently used characters, while separation pairs farther away represent less frequently used characters or commands. This local differentiation allows comprehensive data input coverage while optimizing input speed by placing commonly accessed inputs in easily reachable positions.
3Area of stationary object
If the display screen area is increased, then multimedia and video quality improve, but input device space becomes insufficient
Solution Approach 1:
The input device is divided into a compact reference block and distributed separation pairs along a reference line. This segmentation allows the input device to occupy minimal space while maintaining full input functionality. The reference block serves as a small central anchor, and separation pairs are sparsely distributed along the reference line, maximizing space efficiency and allowing larger display areas in portable devices.
Solution Approach 2:
The input device utilizes a one-dimensional arrangement along a reference line rather than a two-dimensional grid, significantly reducing the space required for input functionality. This dimensional optimization allows portable devices to allocate more screen real estate for multimedia and video displays while maintaining a functional input device within the constrained space of the reference line.
4Measurement precision
If separation pairs are arranged along a reference line with a reference block, then input position recognition is improved, but device complexity increases
Solution Approach 1:
The input device is segmented into a reference block containing three separation pairs and additional separation pairs distributed along a reference line. This segmentation provides clear positional markers that improve input position recognition. The reference block serves as a recognizable anchor point, and the linear arrangement of separation pairs creates a simple mental model for users, improving recognition without requiring complex structures.

AI summary
A data input device and method are provided. The data input device provides an input module, which may be applied to electronic devices or portable terminals, consisting of a number of separation pairs, and the input module includes a number of A separated indication positions and a number of B separated indication positions which are disposed as each A-B type based on a predetermined separation reference line, in two sides, that is, an A separated segment and a B separated segment which are ambilaterally divided based on the separation reference line, so that a data input may be individually or continuously performed by means of an input selection to the one or more separated indication positions.
