Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual washing operation is performed by worker, then washing can be done, but work result varies according to worker skill level and productivity decreases

Engineering Contradiction:
Improvewashing quality consistencyVSAvoidwashing speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical washing operation with an automated robotic arm system equipped with spray nozzles. The robot arm moves along a predetermined path to spray washing water on carcasses, eliminating dependence on worker skill levels while maintaining consistent washing quality and enabling higher productivity through automated operation.

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

Solution Approach 2:

The system changes the operational parameters from manual control to automated control with precise positioning. The robot arm follows a predetermined path with controlled spray timing and water pressure parameters, ensuring consistent washing quality regardless of operator variability while increasing overall washing speed.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If worker performs repeated washing operations, then washing task is completed, but musculoskeletal disorders occur

Engineering Contradiction:
Improvewashing throughputVSAvoidworker health impact
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes the human worker's mechanical arm movements with an automated robotic arm system. The robot performs all repetitive washing motions along a predetermined path, completely eliminating physical strain on workers while maintaining high washing throughput capability.

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

3Reliability

If worker continuously watches carcasses during washing, then monitoring is performed, but post-traumatic stress occurs

Engineering Contradiction:
Improvecarcass monitoringVSAvoidworker psychological impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the need for continuous human visual monitoring with an automated sensor system. Sensors detect the position of carcasses and the robot arm, enabling automatic adjustment of washing parameters and path planning without requiring worker presence or attention, thereby eliminating psychological stress while maintaining reliable monitoring.

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

4Manufacturing precision

If high pressure washing water is sprayed, then foreign matter is removed, but worker injury risk increases

Engineering Contradiction:
Improveforeign matter removal effectivenessVSAvoidworker injury risk
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual high-pressure washing with an automated robotic arm that precisely controls spray direction and pressure application. The robot can adjust spray parameters dynamically based on sensor feedback, maintaining effective foreign matter removal while eliminating the risk of worker injury from uncontrolled high-pressure water.

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

Solution Approach 2:

The system uses sensors to detect carcass position and adjust spray parameters in real-time. This feedback mechanism ensures that high-pressure water is applied only where needed and at safe distances, maintaining washing effectiveness while preventing worker injury through automated control.

Inventive Principle:
Principle #23Feedback

5Productivity

If maximum washing speed is maintained, then productivity is high, but washing accuracy decreases

Engineering Contradiction:
Improvecarcasses washed per dayVSAvoidwashing accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent replaces manual washing with an automated robot arm that can operate at high speeds while maintaining precision through programmable motion control. The robot follows a predetermined path with accurate positioning, enabling high throughput without sacrificing washing accuracy that would occur with rushed manual operation.

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

Solution Approach 2:

The system pre-calculates the optimal washing path and parameters before operation begins. This preliminary planning allows the robot to execute high-speed washing with maintained accuracy, as the optimal trajectory and spray timing are predetermined based on carcass detection data.

Inventive Principle:
Principle #10Preliminary action
