Solution Overview

Problem

There is a need to allow user interaction with apparatuses that lack a user input interface, such as smart cards, to perform actions like menu navigation and service selection.

Innovation Solution

Establish a communication channel between the apparatus and a smart card equipped with a biometric sensor to capture non-biometric data, which is then used to control the apparatus's actions, such as menu scrolling and service selection, through a user output interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the apparatus is devoid of user input interface to reduce cost and hardware complexity, then manufacturing cost and device complexity are reduced, but user interaction capability is lost

Engineering Contradiction:

Improvemanufacturing costVSAvoiduser interaction capability

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent introduces a smart card as an intermediary device that contains a biometric sensor. The smart card acts as a mediator between the user and the apparatus, capturing user interactions through the biometric sensor and transmitting control signals to the apparatus via communication channel, thereby enabling user interaction without requiring input interfaces on the apparatus itself

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces mechanical input interfaces (buttons, switches, keyboards) with a biometric sensing system. Instead of using physical mechanical components for user input, the system uses a biometric sensor to detect user actions and converts them into electronic control signals, eliminating the need for complex mechanical input hardware

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If the apparatus is devoid of user input interface to reduce hardware complexity, then device complexity is reduced, but the ability to select features and services is lost

Engineering Contradiction:

Improvehardware architectureVSAvoidfeature selection capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The smart card serves as an intermediary that contains the biometric sensor and communication interface. It captures user interactions, processes them, and transmits appropriate control commands to the apparatus, enabling feature selection and service access without requiring the apparatus to have complex input hardware

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The biometric sensor in the smart card serves multiple functions: it detects user presence, captures user interactions (presses, slides, rotations), and transmits control signals. This multi-functional component replaces what would otherwise require multiple separate input devices, reducing overall system complexity while maintaining versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)
