Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional breach load screw-in design is used, then the device has been in use for a long time and functions as intended, but there have not been improvements or new designs that will function more effectively

Engineering Contradiction:
Improvefunctional reliabilityVSAvoiddesign adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The piston assembly is divided into separate modular components including the piston body, breach plate, mounting plate, and sealing elements. This segmentation allows each component to be optimized independently while maintaining overall reliability, and enables adaptability through reconfiguration of modular parts for different applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The piston assembly is designed with universal mounting plates and standardized interfaces that allow the same basic design to be adapted for various applications and orientations. The modular component structure enables the assembly to function effectively across different scenarios while maintaining consistent performance.

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

2Power

If an explosive force is used to instantaneously propel or move objects, then realistic action is produced, but the design lacks improvements to provide consistent power based on the size of explosive or pneumatic force

Engineering Contradiction:
Improveinstantaneous propulsive powerVSAvoidpower consistency
Core Design Contradiction:
PowerVSManufacturing precision

Solution Approach 1:

The design incorporates adjustable parameters including piston surface area, chamber volume, and explosive charge size that can be varied to achieve consistent power output. By systematically controlling these parameters, the assembly delivers predictable and repeatable force regardless of the specific explosive or pneumatic source used.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The design accepts both explosive and pneumatic force sources, effectively substituting one energy delivery mechanism for another while maintaining the same mechanical output. This substitution capability allows for consistent power delivery by choosing the appropriate energy source based on application requirements.

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

3Adaptability or versatility

If the piston assembly is designed for secure attachment and versatility in orientation, then it can be adapted for various applications including underwater use, but the device complexity increases

Engineering Contradiction:
Improveapplication versatilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting plate incorporates multiple mounting configurations and orientation options within a single standardized component design. This universal approach allows the assembly to be adapted for different applications and environments including underwater use without requiring fundamentally different designs, thereby managing complexity while maintaining versatility.

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

Solution Approach 2:

The assembly features nested or integrated components where mounting elements, sealing surfaces, and structural supports are incorporated within the overall piston structure. This nesting approach reduces the number of separate parts and simplifies assembly while maintaining adaptability for various applications.

Inventive Principle:
Principle #7Nested doll (Nesting)

Implementation Method 1

An explosive charge is placed into the piston assembly. The charge is then activated which produces a contained explosive force that actuates the piston

Methodology Applied
Scientific EffectExplosion: Explosion

Implementation Method 2

At least one ventilation bore extends through the cylinder to allow explosive or pneumatic gas to escape, thereby relieving pressure within the piston assembly

Methodology Applied
Scientific EffectPressure relief: Depressurisation

AI summary

An explosively propelled piston assembly (EPPA) comprising an optional mounting plate; at least one lower cylinder fastener; a breach bolt with a base and an upward extending member; a breach plate having a plurality of surround openings; a breach gasket having a plurality of openings; a combustion piston with a base, a center opening, and upward extending side wall and a threaded opening; a piston dampening ring; a combustion cylinder having an upper section, a lower section, upward extending members and at least one ventilation bore; and a plurality of threaded plate fasteners. Once the EPPA is assembled, an explosive charge is placed into the EPPA. The charge is then activated which produces a contained explosive force that actuates the piston, causing the piston to extend outward, applying the force onto an object in contact with or adjacent to the EPPA. The force can be used to produce pushing, flipping, rolling or other movement of the object.
