Solution Overview

Problem

Conventional image forming apparatuses lack user-friendliness in automatically detecting and setting modes for users approaching the device, often requiring users to carry non-contact IC cards or operate complex interfaces, and struggle to identify specific users among multiple individuals.

Innovation Solution

The apparatus employs a communication unit to detect and analyze wireless LAN radio waves from registered host devices, determining user identification and setting the device to the appropriate mode based on signal intensity and duration, eliminating the need for user operation or additional equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the apparatus uses non-contact IC cards for user identification, then user identification capability is improved, but device complexity and ease of operation deteriorate due to requiring additional equipment and complex user actions

Engineering Contradiction:
Improveuser identification capabilityVSAvoiduser operation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The communication unit automatically detects wireless LAN signals from host devices and performs user identification without requiring users to carry IC cards or perform any special operations. The system serves itself by autonomously acquiring user information through existing wireless communication infrastructure.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent extracts the user identification function from the communication unit itself rather than requiring a separate IC card reading device. The communication unit leverages its existing wireless signal reception capability to identify users based on their host device signals, eliminating the need for dedicated identification hardware.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the apparatus automatically detects users approaching, then ease of operation is improved, but device complexity worsens due to requiring additional sensors or detection equipment

Engineering Contradiction:
Improveautomatic mode settingVSAvoiddetection equipment complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The communication unit performs multiple functions: it not only communicates with host devices for printing operations but also detects user approach and performs user identification. By making the communication unit multi-functional, the patent avoids adding separate detection sensors or equipment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the user approach detection function and user identification function into the existing communication unit. Instead of adding separate sensors and processing systems, these functions are merged into the wireless communication infrastructure already present in the apparatus.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If the apparatus requires users to operate complex interfaces for mode setting, then manufacturing precision is improved through explicit user control, but ease of operation deteriorates

Engineering Contradiction:
Improvecontrol precisionVSAvoidinterface operation simplicity
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The apparatus performs preliminary actions by automatically detecting user approach and pre-setting the operating mode before the user actually operates the device. The communication unit identifies the user and configures appropriate settings in advance, so when the user approaches, the device is already prepared with correct modes, eliminating the need for complex interface operations.

Inventive Principle:
Principle #10Preliminary action
