Foot-Operated Data Entry Pad with Radial Buttons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data entry systems in dental care and other fields require manual operation, limiting the ability to enter complex data without using hands, and existing foot-operated devices can only handle simple binary data sets.
Innovation Solution
A foot-operated data entry pad with radially arranged foot buttons, a joystick-type controller, and an optional automated voice system, allowing for the entry of alphanumeric and numeric data by pressing buttons for varying durations or repeatedly, and seamlessly integrating with existing computer hardware and software to mimic mouse and keyboard inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional foot-operated devices are used, then hands-free operation is achieved, but data entry capability is limited to simple binary data sets
Solution Approach 1:
The foot-operated device is segmented into multiple independent buttons arranged in a radial pattern, allowing each button to represent different data values. This segmentation enables the device to enter complex numeric and alphanumeric data by selecting different buttons, rather than being limited to simple binary input from a single pedal position.
Solution Approach 2:
The device transitions from one-dimensional single-pedal positioning to a two-dimensional radial button array. This dimensional change allows multiple data values to be accessed by selecting different angular positions around the heel rest, significantly expanding data entry capability while maintaining hands-free operation.
2Reliability
If multiple workers are used for data entry, then measurement tasks can be completed, but productivity and efficiency are reduced
Solution Approach 1:
The foot-operated data entry pad is designed as a universal input device that can replace both the measuring instrument activation and data entry functions. By integrating measurement control and data input capabilities into a single foot-operated interface, the device allows one worker to perform tasks that previously required two or more workers, thereby improving productivity without compromising data entry accuracy.
3Device complexity
If existing foot-operated devices are used, then simple binary data can be entered, but complex alphanumeric data entry is not possible
Solution Approach 1:
The device incorporates dynamic input modes where button press duration determines the type of data entered. Short presses may input single digits, while longer presses or repeated presses enable entry of multi-digit numbers and alphanumeric characters. This dynamic behavior allows the relatively simple radial button structure to handle complex data types without requiring a full keyboard layout.

AI summary
A foot operated data entry pad has a plurality of foot buttons. The foot buttons are used to enter data values—e.g., numbers or symbols separately or in combination. Each button is capable of entering different data values, preferably depending on the length of time that it is pressed or on the number of times that it is pressed in succession. A small controller may be included to allow the user to control the computer's pointer, allowing the user to switch between data entry fields, as with a mouse. An automated voice system, or other audible and/or visual indicator system, may also be included to help the user keep track of the data value as it changes and is entered. Various embodiments are capable of entering a variety of alphanumeric data rather than a simple binary-type data set, such as yes/no or on/off, or instructions, such as a joystick used with a flight simulator program. Multiple data entry pads may optionally be used in conjunction.
