Touch Smart Card Button Integration for Space Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The internal space of smart cards is limited due to the need for multiple functions and elements, leading to compression of components and reduced battery life, making it difficult to add new features or enhance functionality.
Innovation Solution
A multifunctional touch smart card design that replaces the conventional mechanical button with a touch button, allowing for flexible circuit layout and integration of additional features by using a touch button integrated with a contact metal piece, which can control the smart card's operations and improve battery endurance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functions and elements are integrated into a smart card, then the functionality and versatility of the smart card are improved, but the internal space becomes crowded and battery life decreases
Solution Approach 1:
The patent utilizes the front surface area of the smart card by integrating a touch button into the contact metal piece, effectively using the two-dimensional surface space rather than consuming additional internal three-dimensional space. This allows the button to be disposed in an area that would otherwise be unused, maintaining battery life while adding functionality.
Solution Approach 2:
The contact metal piece is designed to serve dual purposes: it maintains its traditional function for information transmission according to ISO7816 standard, and simultaneously functions as a touch button for controlling smart card operations. This multi-functionality approach adds control capabilities without requiring separate dedicated space for a button.
2Ease of operation
If a mechanical button is added to the smart card for control functions, then the ease of operation is improved, but the internal space is compressed and new elements cannot be added
Solution Approach 1:
The patent merges the button structure with the contact metal piece, combining two previously separate elements into one integrated component. The touch button is disposed in the front surface area of the contact metal piece, allowing control functionality to be added without increasing device complexity or consuming additional internal space.
3Productivity
If the contact metal piece area is fully utilized, then the productivity and space efficiency are improved, but the ease of operation for touch control is reduced
Solution Approach 1:
The patent applies local quality by creating a specific touch-sensitive region on the front surface of the contact metal piece. This localized touch button area is distinguished from the rest of the contact metal piece, allowing touch control functionality to be added without compromising the overall space efficiency of the contact metal piece structure.
