Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large compressor or complex apparatus is used to refill the pressure chamber, then the pressure chamber can be refilled to maintain predetermined pressure, but the device complexity and equipment size increase

Engineering Contradiction:
Improvepressure maintenanceVSAvoidrefilling apparatus
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent makes the pressure chamber volume adjustable through a movable partition wall that can be positioned at different levels. This dynamic adjustment allows the system to maintain predetermined pressure with a simpler refilling apparatus, as the volume can be adapted to match the refilling capability of smaller compressors or pumps.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the physical parameter of pressure chamber volume to enable refilling with simpler equipment. By adjusting the volume parameter, the predetermined pressure can be achieved even when using smaller, less complex refilling apparatus, thus resolving the contradiction between pressure maintenance reliability and device complexity.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the pressure chamber volume is fixed, then the structure is simple, but the ability to adjust pressure settings is limited

Engineering Contradiction:
Improvepressure adjustmentVSAvoidchamber structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The partition wall is designed to be movable rather than fixed, allowing the pressure chamber volume to be dynamically adjusted. This enables different pressure settings while adding minimal structural complexity, as the partition wall can be guided along predetermined paths or positions within the chamber.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pressure chamber is segmented into adjustable sections by the movable partition wall. This segmentation allows independent adjustment of volume while maintaining a relatively simple overall structure, enabling versatile pressure settings without requiring a completely complex redesign of the chamber.

Inventive Principle:
Principle #1Segmentation

3Loss of energy

If a small simple compressor is used for refilling, then the equipment size is reduced, but the ability to reach predetermined pressure levels is compromised

Engineering Contradiction:
Improveequipment sizeVSAvoidpressure level achievement
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

By changing the volume parameter of the pressure chamber through movable partition walls, the system enables smaller compressors to achieve the same pressure levels. The reduced volume allows smaller equipment to generate sufficient pressure, thus reducing equipment size while maintaining pressure level achievement capability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The dynamic adjustment of chamber volume allows the system to optimize the pressure generation process for smaller compressors. By adjusting the volume to match the capabilities of compact refilling equipment, the system achieves predetermined pressure levels effectively while minimizing equipment size and energy loss.

Inventive Principle:
Principle #15Dynamics

AI summary

To provide a driver that can be reduced in the amount of gas to be injected into a pressure chamber. The driver (10) has: an impactor (12) configured to hit a stopper (58) by moving from a first position toward a second position; a pressure chamber (13) to be filled with gas for moving the impactor (12) from the first position toward the second position; a control mechanism configured to move the impactor (12) from the second position toward the first position; and a gas injection portion configured to inject gas into the pressure chamber (13), wherein the impactor (12) is capable of taking a standby position between the second position and the first position, and the control mechanism is configured to stop the impactor (12) at an adjustment position closer to the second position than the standby position before gas is injected into the pressure chamber (13).
