Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If operator intervention is used to load and unload spinning cans on transport trolleys, then the system structure remains simple, but the sliver supply becomes unreliable and production stoppages occur due to dependency on personnel

Engineering Contradiction:
Improvesliver supply reliabilityVSAvoidtransport system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The transport vehicle is equipped with an autonomous manipulator unit that can independently detect spinning cans, navigate to spinning machines, and perform loading/unloading operations without human intervention. The vehicle serves itself by autonomously managing the sliver supply process, thereby improving reliability while maintaining reasonable system complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical operation of operators loading and unloading spinning cans is replaced by an automated manipulator unit with gripper. This substitution eliminates human dependency in the sliver supply process, ensuring continuous and reliable operation of spinning machines

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual operation is used for transport trolley adjustment and can handling, then the device complexity is low, but productivity decreases due to personnel dependency and potential production stoppages

Engineering Contradiction:
Improvesliver supply efficiencyVSAvoidautonomous system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The transport vehicle autonomously performs all operations including navigation to spinning machines, detection of can positions, manipulation of spinning cans, and return trips. This self-service capability eliminates idle time and ensures continuous sliver supply, significantly improving productivity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The autonomous manipulator unit is pre-equipped with sensors and navigation systems that enable it to proactively seek out spinning machines that need sliver replenishment. The vehicle performs preliminary detection and preparation actions before actual can handling, ensuring seamless and efficient sliver supply

Inventive Principle:
Principle #10Preliminary action

3Extent of automation

If autonomous manipulator unit with gripper and adjusting device is implemented, then personnel-independent operation is achieved, but the device complexity increases

Engineering Contradiction:
Improveautonomous operation levelVSAvoidmanipulator system complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The manipulator unit is designed as a multi-functional system that combines navigation, detection, gripping, and positioning capabilities in a single integrated unit. This universal design achieves high-level autonomy while avoiding the need for separate specialized devices for each function, thereby controlling overall system complexity

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

Solution Approach 2:

The patent combines the travel drive, transport platform, and manipulator unit into an integrated autonomous vehicle system. The control unit coordinates all subsystems (navigation, manipulation, sensing) working together, achieving high automation through functional integration rather than through multiple independent complex systems

Inventive Principle:
Principle #5Merging (Combining)
