Information Terminal Cursor Jump to Enter Key

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Biological sample measurement devices with arrayed character keys beneath the display component are bulky and inconvenient due to the long distance the cursor must travel between the last selected character key and the enter key, making input operations inefficient.

Innovation Solution

The device features a display component and an input component with a select key to move a cursor over character keys and a home key to directly move the cursor from the selected character key to the enter key, improving input efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If character keys are displayed within the display component and the enter key is positioned far from the character keys, then the device size is reduced, but the cursor travel distance increases making input operations less convenient

Engineering Contradiction:

Improvedevice sizeVSAvoidinput operation convenience

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The enter key is pre-positioned adjacent to the character key area, and when the cursor reaches the last character key, the system automatically moves it to the enter key, preparing the next action in advance and eliminating unnecessary cursor movement

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The enter key serves dual purposes: it can be reached by normal cursor movement from character keys, or automatically jumped to from the last character key position, making it accessible through multiple paths and improving operational efficiency

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Quantity of substance

If the enter key is positioned far from the last selected character key, then more character keys can be displayed, but the time to reach the enter key increases

Engineering Contradiction:

Improvenumber of character keysVSAvoidtime to reach enter key

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The enter key is strategically positioned adjacent to the character key area from the beginning, and the system prepares for automatic cursor movement by detecting when the last character key is selected, thereby eliminating time loss without reducing character key quantity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The manual mechanical cursor movement process is replaced with an automatic cursor movement mechanism that detects the selection state and autonomously moves the cursor to the enter key, eliminating the time penalty associated with distant key positioning

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

In an information terminal device (100), a display component (2) displays, on the basis of commands from a controller (9), a plurality of character keys, an enter key (20) for entering input information including one or more characters inputted by selecting the plurality of character keys, and a selection marker indicating one of the plurality of character keys being selected. An input component (3) includes a select key (5) that causes the controller (9) to successively move the selection marker displayed on the display component (2) over the plurality of character keys so as to select one of the character keys, and a change key (8) that causes the controller (9) to change a display content of the display component (2). When the change key (8) has been operated in a state in which the input information is being displayed on the display component (2), the controller (9) moves the selection marker displayed on the display component (2) from the selected character key directly to the enter key (20).
