Solution Overview

Problem

Conventional vibratory apparatuses are poorly adapted to retain round members like pipes or logs, leading to a risk of breakage or dislodgment, and inefficient energy transfer for penetration due to indirect vibration application.

Innovation Solution

A vibratory apparatus with an inner housing that directly contacts cylindrical members through pivotally connected jaws, providing three-point gripping and enhanced vibration transmission, reducing the risk of breakage and energy loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional jaws are used to retain round members, then the apparatus can hold members, but the members may break or become dislodged during application

Engineering Contradiction:

Improvemember retention stabilityVSAvoidmember breakage and dislodgment risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The jaw assembly is segmented into multiple jaws (typically three or more) that can be independently positioned to contact the member at multiple points. This segmentation allows each jaw to apply force at optimal locations, distributing the retention load and preventing member breakage or dislodgment during penetration operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inner surfaces of the jaws are equipped with localized gripping features such as teeth, ridges, or textured surfaces at specific contact points. These local quality enhancements increase friction and mechanical interlocking between the jaws and round members, significantly improving retention stability without affecting the overall jaw structure.

Inventive Principle:

Principle #3Local quality

2Device complexity

If the vibrator means does not directly contact the members, then the apparatus structure is simpler, but significant energy is expended to obtain sufficient vibration of the members

Engineering Contradiction:

Improvevibration transmission structureVSAvoidenergy expenditure for member vibration

Core Design Contradiction:

Device complexityVSUse of energy by moving object

Solution Approach 1:

The jaws serve as an intermediary medium between the vibrator means and the members. The vibrator means generates vibrations that are transmitted through the jaws, which directly contact the members. This intermediary arrangement allows efficient energy transfer from the vibrator to the members while maintaining a structurally simple apparatus design.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The vibrator means generates mechanical vibrations at frequencies and amplitudes optimized for penetrating the target material. These vibrations are transmitted through the jaws to the members, reducing the energy required compared to static forcing methods. The vibratory action facilitates easier penetration and reduces the overall energy expenditure of the system.

Inventive Principle:

Principle #18Mechanical vibration

3Adaptability or versatility

If conventional hinge attachment is used, then the apparatus can be connected to device arms, but the vibration transmission to members is indirect and inefficient

Engineering Contradiction:

Improveapparatus connection capabilityVSAvoidvibration energy loss in transmission

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The jaws are pre-configured with inner surfaces specifically shaped and positioned to directly contact and grip round members before vibration is applied. This preliminary positioning ensures optimal contact geometry is established in advance, maximizing vibration transmission efficiency and minimizing energy loss during the penetration operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The jaw assembly incorporates dynamic adjustment capabilities through hinge attachments and movable components, allowing the jaws to adapt their position and orientation during operation. This dynamic adjustment maintains optimal contact between the jaws and members throughout the penetration process, ensuring efficient vibration transmission and reducing energy losses.

Inventive Principle:

Principle #15Dynamics

AI summary

A vibratory apparatus providing increased vibration of members held for penetrating a material with the member, by holding the members directly against the vibrating unit using the jaws, thus providing a greater amount of vibration directly transferred to the members for penetrating the material therewith while losing less energy. The apparatus can hold cylindrically shaped members at three separate points of contact or gripping positions for improved, more stable and secure holding thereof. The apparatus can be used to force a variety of different types of members into and out of the material, with or without the use of adaptor attachment components.
