Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a building management robot is deployed to provide various management operations and services, then building management efficiency and service capability are improved, but the ability to recognize and authenticate various persons and provide customized services is insufficient

Engineering Contradiction:
Improvebuilding management efficiencyVSAvoidperson recognition and authentication capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The building management robot is equipped with multiple functional modules including wireless communication modules for identification device recognition, camera for image data acquisition, processor for user recognition and authentication level confirmation, and service provision capabilities. This multi-functional integration enables the robot to handle various tasks such as security operations, guard assistance, parking lot management, cleaning, and customized services for different user types (residents, visitors, delivery personnel), thereby resolving the contradiction between productivity improvement and adaptability enhancement

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

Solution Approach 2:

The robot's authentication and service provision system is divided into distinct functional segments: identification device recognition module, image data acquisition module, user recognition module, authentication level confirmation module, and service provision module. Each segment handles a specific aspect of the authentication process, allowing the system to efficiently manage complex person recognition and authentication tasks while maintaining high building management productivity

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the robot provides customized services based on authentication levels, then service quality and user experience are improved, but system complexity increases

Engineering Contradiction:
Improveservice qualityVSAvoidauthentication and service system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system applies different authentication levels and service provisions to different users based on their local characteristics. The processor determines authentication levels (first authentication level for residents, second authentication level for visitors, third authentication level for delivery personnel) and provides customized services accordingly. This local quality approach allows high service quality through personalization while managing complexity by using standardized authentication level categories

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system uses authentication level as a key parameter to simplify the complex task of providing customized services. By changing the parameter from detailed user analysis to discrete authentication levels (first, second, third levels), the system achieves high service quality through differentiated treatment while reducing computational and operational complexity

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the robot uses multiple wireless communication modules for positioning and identification device recognition, then positioning accuracy and authentication reliability are improved, but device complexity and energy consumption increase

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidcommunication module complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The wireless communication modules act as intermediaries between the robot and identification devices. By using standardized wireless communication protocols and modules, the system achieves high authentication reliability through multiple recognition points without significantly increasing device complexity. The communication modules mediate the interaction between the robot's positioning system and user identification devices

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If the robot monitors elevator boarding areas and detects persons waiting for elevators, then user convenience and safety are improved, but measurement precision requirements and processing complexity increase

Engineering Contradiction:
Improveuser convenienceVSAvoidperson detection precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The robot performs preliminary actions by monitoring elevator boarding areas and detecting persons waiting for elevators before the actual elevator service is provided. The processor analyzes image data from the camera to identify waiting users and determines when to call the elevator or provide assistance. This preliminary monitoring improves user convenience and safety by ensuring timely service while using standard image recognition techniques to manage measurement precision requirements

Inventive Principle:
Principle #10Preliminary action
