Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If traditional intermittent mechanisms pause continuous conveying devices to achieve intermittent operation, then the intermittent movement function is realized, but the prime mover must start and stop repeatedly causing increased energy consumption

Engineering Contradiction:

Improveenergy consumptionVSAvoidintermittent movement control

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The conveying device is segmented into multiple conveying units that can operate independently. Each unit has its own driving mechanism, allowing individual control of movement and stopping. This enables intermittent conveying without requiring the entire system to pause and restart, as only specific segments need to stop temporarily while others continue operating.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device employs dynamic control of multiple conveying units with different operational states. Some units are in motion while others are stationary, creating a dynamic intermittent conveying pattern. This dynamic approach allows the system to maintain continuous operation of the prime mover while achieving intermittent material transport through coordinated control of individual units.

Inventive Principle:

Principle #15Dynamics

2Loss of energy

If traditional intermittent mechanisms use repeated starting and stopping to achieve intermittent function, then the intermittent operation is achieved, but braking deceleration and driving acceleration cause energy loss

Engineering Contradiction:

Improveenergy loss during braking and accelerationVSAvoidintermittent conveying efficiency

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The system performs preliminary positioning and preparation in advance by having multiple conveying units ready at different positions. When intermittent conveying is needed, the system simply activates or deactivates specific pre-positioned units rather than stopping and restarting the same unit. This eliminates the need for repeated braking and acceleration cycles.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The prime mover operates continuously without interruption, maintaining constant rotation or motion. The intermittent conveying effect is achieved not by stopping the prime mover but by selectively engaging or disengaging individual conveying units along the path, ensuring continuous useful action from the power source while achieving intermittent material transport.

Inventive Principle:

Principle #20Continuity of useful action

3Adaptability or versatility

If continuous conveying devices are used for material transportation, then material transport is efficient, but operations such as taking and discharging materials within specific time intervals cannot be performed

Engineering Contradiction:

Improveability to perform operations within specific time intervalsVSAvoidmaterial transportation efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The conveying system is divided into multiple independently controllable segments or units. Each segment can be activated or deactivated individually, allowing material to be taken or discharged at specific intervals by controlling which segments are operational. This maintains overall conveying efficiency while providing the adaptability to perform operations within specific time windows.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements periodic activation and deactivation of specific conveying units to create intermittent conveying patterns. By periodically controlling which units are active, the system can perform material taking and discharging operations at regular intervals while maintaining continuous operation of the overall conveying system, thus preserving productivity while gaining operational flexibility.

Inventive Principle:

Principle #19Periodic action

AI summary

Disclosed is an intermittent moving mechanism, which belongs to the technical field of conveying devices and includes a guide rail; a sliding block moving along the guide rail, two stop blocks arranged at intervals, wherein a distance between the two stop blocks is greater than a length of the sliding block along an extension direction of the guide rail, and the sliding block is positioned between the two stop blocks; and a reciprocating movement structure, configured to push the two stop blocks to move synchronously and reciprocally along an extension direction of the guide rail. The reciprocating moving structure in the intermittent mechanism continuously operates, which avoids repeated starting and stopping and speed changes of the prime mover, and is beneficial to reducing the operation energy consumption and reducing the noise pollution to the environment.
