Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joints for machinery components, such as those used in portable shakers, are complex to produce, costly, difficult to install, and require extensive dismantling for maintenance or replacement, with limited adjustability and high production costs, restricting their use and adoption.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the joint is designed with reversible connection means, then ease of manufacture and installation is improved, but the structural complexity increases
Solution Approach 1:
The joint is divided into separate components: a first interconnection element connectable to the machine body, a second interconnection element connectable to the vibrating rod, and constraint means positioned between them. This segmentation allows each component to be manufactured independently and simplifies assembly and disassembly operations.
Solution Approach 2:
The joint incorporates adjustable constraint means that can modify the degree of freedom of relative rotation between the two interconnection elements. This dynamic adjustment capability allows the joint to adapt to different operational requirements while maintaining a relatively simple overall structure through standardized components.
2Adaptability or versatility
If the joint allows adjustable relative rotation freedom, then adaptability is improved, but device complexity increases
Solution Approach 1:
The constraint means are designed to be adjustable, allowing modification of the degree of freedom for relative rotation between the first and second interconnection elements. This enables the joint to adapt to different torsional resistance requirements while using standardized, relatively simple mechanical components rather than complex control systems.
Solution Approach 2:
The joint allows changing the parameter of rotational freedom by adjusting the constraint means. This enables the same joint structure to operate under different torsional conditions without requiring multiple specialized joints, thereby improving adaptability while controlling complexity.
3Reliability
If the joint is contained within the machine body, then reliability is improved, but ease of repair worsens
Solution Approach 1:
The joint components are designed as separable elements that can be connected to and disconnected from the machine body without dismantling it. The first interconnection element can be attached to the machine body while the second element connects to the vibrating rod, allowing the joint to be removed as an assembly for repair or replacement while maintaining system reliability during operation.
4Strength
If the joint uses irreversible connection, then strength is improved, but ease of operation worsens
Solution Approach 1:
The connection means are designed to provide strong, reliable connections during normal operation while allowing controlled disconnection when needed. The constraint means can maintain firm engagement for strength during vibration operations, but can be adjusted or released by the operator when maintenance or rod replacement is required, balancing strength with operational ease.

AI summary
A joint which can be interposed between two parts of a machinery comprises a first and a second interconnection element which can be connected, respectively, to a first and a second part of a machinery and related constraint means interposed between the first and the second interconnection element so as to realize a relative rotation between the interconnection elements around an ideal axis; the joint also includes reversible connection means active between the first interconnection element with respect to the first part and/or active between the second interconnection element with respect to the second part.
