VSEngineering Contradiction Analysis

1Ease of operation

If manual operator alignment is used to position the coupling module, then the operator can control the horizontal position of the ground facility, but the operation becomes complex and time-consuming due to lack of training and time pressure

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs self-alignment by automatically determining its own horizontal position using the position sensor and adjusting the coupling module accordingly, eliminating the need for manual operator intervention and reducing both operational complexity and time requirements

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The position sensor provides continuous feedback about the horizontal position of the ground facility to the control unit, which then automatically adjusts the coupling module to achieve proper alignment, creating a closed-loop control system that simplifies operation and reduces time

Inventive Principle:
Principle #23Feedback

2Reliability

If the coupling module is manually aligned by the operator, then the horizontal position can be adjusted, but misalignment occurs frequently due to operator inexperience and time pressure

Engineering Contradiction:

Solution Approach 1:

The manual mechanical alignment process is replaced with an automated electronic control system that uses a position sensor to detect horizontal position and a control unit to automatically adjust the coupling module, eliminating human error and improving reliability

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

Solution Approach 2:

The system automatically monitors and adjusts its own horizontal alignment using the position sensor and control unit, ensuring consistent and accurate positioning without relying on operator skill or attention, thereby improving reliability while reducing operational complexity

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If a position sensor is added to automatically measure the inclination of the ground facility, then the horizontal alignment is improved, but the device complexity increases

Engineering Contradiction:

Solution Approach 1:

Complex manual alignment procedures are replaced by a straightforward electronic measurement system using a position sensor that automatically detects horizontal inclination, and a control unit that processes the data and actuates adjustment, simplifying the overall system despite adding electronic components

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

Solution Approach 2:

The position sensor enables the system to self-measure its horizontal alignment status, and the control unit automatically processes this information to adjust the coupling module, achieving high precision alignment while keeping the control logic integrated and manageable
