Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple sensor devices are used to detect objects on multiple sides, then detection capability is improved, but device complexity increases

Engineering Contradiction:
Improvedetection capabilityVSAvoidhardware and software structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple sensor devices are merged into a single integrated sensor device that can detect objects on multiple sides simultaneously. This combines the functionality of what would otherwise require multiple separate sensors, reducing hardware complexity while maintaining comprehensive detection capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sensor device is designed with multi-functionality to perform detection on multiple sides and in multiple directions. This universal sensor can replace multiple specialized sensors, simplifying the overall system architecture while preserving the ability to detect objects from various angles and positions.

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

2Ease of operation

If automatic search mode is implemented to choose objects independently, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveuser interaction requirementVSAvoidcontrol software
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The floor conveyor system performs self-service by automatically selecting and following objects without requiring operator intervention. The control unit independently processes sensor data, identifies target objects, and navigates to them, freeing the operator from manual object selection tasks.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback loops where sensor data continuously informs the control unit about object positions, which then adjusts the conveyor's path accordingly. This closed-loop control enables automatic object following while maintaining adaptability to changing environments.

Inventive Principle:
Principle #23Feedback

3Reliability

If sensor device is mounted at an angle for enhanced detection range, then detection capability is improved, but ease of repair worsens

Engineering Contradiction:
Improvedetection rangeVSAvoidmaintenance accessibility
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The sensor mounting system is segmented into adjustable components that allow the sensor to be positioned at optimal angles for detection while maintaining accessibility for maintenance. The segmented design enables independent adjustment of the sensor angle without affecting other system components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor mounting arrangement is made dynamic and adjustable rather than fixed. This allows the sensor angle to be optimized for detection performance while also being easily repositioned or accessed when maintenance is required, balancing operational effectiveness with serviceability.

Inventive Principle:
Principle #15Dynamics
