Sheet-like Information Device with Cancel Button and Shared Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet-like information-gathering devices lack the ability to easily cancel mistaken button presses and are limited in the number of selection buttons due to the constraints of conductive patterns and terminals on a paper substrate, making them difficult for elderly or disabled users to navigate and requiring small print explanations.
Innovation Solution
A sheet-like information-gathering device with a communication module that includes an IC chip for storing button press information, a controller for managing data, and a wireless communication unit, featuring a cancel button to retract previously recorded information, and a terminal unit with conductive patterns connecting multiple buttons to a common terminal, allowing for easy button selection and correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If each selection button is connected to a terminal having a different conductive pattern, then the button press can be identified, but the total number of selection buttons is limited by the number of terminals of the conductive patterns
Solution Approach 1:
Multiple selection buttons are connected to a common terminal through separate conductive patterns, rather than each button requiring a unique terminal. This merging approach allows multiple buttons to share the same terminal connection, thereby increasing the number of selectable buttons without proportionally increasing the number of terminals.
Solution Approach 2:
The common terminal serves multiple functions by receiving signals from multiple different selection buttons through distinct conductive patterns. This universal terminal design enables the system to handle more button selections without requiring additional terminals for each button.
2Quantity of substance
If many selection buttons are provided on the paper substrate, then more information can be selected, but it is not easy for elderly people or disability people to select an appropriate button and it takes much time to read the explanation generally described in small print
Solution Approach 1:
Selection buttons are arranged in a matrix pattern with multiple rows and columns, utilizing two-dimensional space on the paper substrate. This dimensional arrangement allows for a greater number of buttons to be packed into a compact area while maintaining reasonable spacing and accessibility for users.
3Area of stationary object
If the size of the paper substrate is limited, then the device remains portable and manageable, but it is not easy to increase the number of terminals of the conductive patterns
Solution Approach 1:
Multiple conductive patterns converge at a common terminal, reducing the total number of terminal connections required on the paper substrate. This merging of conductive paths allows for more buttons to be implemented within the same substrate area without proportionally increasing terminal count.

AI summary
To provide a user-friendly information-gathering device enabling users to select buttons easily. An information-gathering device has a plurality of selection buttons, a communication module, and a cancel button. The communication module has an IC chip and a button cell. The IC chip has a storage which stores information for identifying the pressed selection button and information about the time of the press, in chronological order, a controller which performs control to store the information in the storage, and a wireless communication unit. When the cancel button is pressed, the controller stores, in the storage, information requesting to cancel press information about the selection button pressed immediately before the cancel button is pressed.
