Solution Overview

Problem

The existing commodity sales data processing apparatuses are vulnerable to unauthorized use since they can be easily demounted from docking stations, allowing unauthorized individuals to perform illegal operations.

Innovation Solution

An information processing apparatus with an input device, an acquisition unit, and a processor that permits operation inputs when mounted on a docking station but requires user authentication via biological information, such as face images, when demounted, ensuring only authorized operators can use the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the information processing apparatus is made easily demountable from the docking station for portability, then ease of operation is improved, but security against unauthorized use deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies dynamics by making the security measures dynamic rather than static. The acquisition unit is activated only when the apparatus is demounted from the docking station, and the processor dynamically adjusts authentication requirements based on the mounting state. This allows the system to be portable while maintaining security only when needed (when demounted), resolving the contradiction between ease of operation and security.

Inventive Principle:
Principle #15Dynamics

2Reliability

If user authentication is always required for operation, then security is improved, but ease of operation deteriorates

Engineering Contradiction:
ImprovesecurityVSAvoidoperation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the operation into two distinct modes: mounted mode and demounted mode. When mounted on the docking station, no authentication is required and operations are convenient. When demounted, authentication is required for security. This segmentation allows the system to provide both convenience and security at appropriate times, resolving the contradiction between security and ease of operation.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the acquisition unit is always activated to capture operator information, then security is improved, but energy consumption increases

Engineering Contradiction:
ImprovesecurityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by activating the acquisition unit only at specific moments when the apparatus is demounted from the docking station, rather than continuously. The processor monitors the mounting state and triggers authentication only when needed. This periodic activation maintains security when necessary while significantly reducing energy consumption compared to continuous activation, resolving the contradiction between security and energy usage.

Inventive Principle:
Principle #19Periodic action

AI summary

In one embodiment, an information processing apparatus (1) is mountable on and demountable from a docking station (2), and has an input device (11), an acquisition unit (42) to acquire information indicating an operator for user authentication, and a processor. When the apparatus (1) is mounted on the docking station (2), the processor permits acceptance of the operation input by the input device (11), without starting up the acquisition unit (42). When the apparatus (1) is demounted from the docking station (2), the processor starts up the acquisition unit (42), and performs user authentication based on the information indicating the operator which has been acquired by the started up acquisition unit (42). When the operator is approved as a specific operator of the information processing apparatus (1), as a result of the user authentication, the processor permits acceptance of the operation input by the input device (11).
