Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibratory screen exciter beams are of unitary construction, which can be heavy and inflexible, limiting their ability to efficiently transmit forces and adapt to varying stress conditions, and often require significant modifications for retrofitting.
Innovation Solution
A modular exciter beam design featuring detachable end fittings and connection members that mount inside the side walls of the vibratory screen, allowing for the transmission of forces between side walls and enabling easier retrofitting and customization to handle different stress conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a unitary construction exciter beam is used, then structural strength is improved, but weight increases and adaptability deteriorates
Solution Approach 1:
The exciter beam is divided into multiple modular segments that can be independently configured and assembled. Each segment can be optimized for specific stress conditions, allowing the overall structure to adapt to varying operational requirements while maintaining structural integrity through standardized connection interfaces.
Solution Approach 2:
The modular segments are designed with universal connection features that allow them to be configured in different arrangements to handle various stress conditions. This multi-functionality enables the same basic segment design to serve multiple purposes across different application scenarios, improving adaptability without sacrificing strength.
2Stability of the object's composition
If a unitary construction exciter beam is used, then structural integrity is improved, but ease of manufacture and retrofitting deteriorates
Solution Approach 1:
By segmenting the exciter beam into standardized modules with consistent connection interfaces, the design maintains structural integrity through proven connection details while dramatically improving ease of manufacture and retrofitting. Each module can be manufactured independently using standardized processes, and retrofitting becomes a matter of modular replacement rather than custom fabrication.
Solution Approach 2:
The modular design allows certain parameters such as segment length, wall thickness, and reinforcement configuration to be varied between modules to match specific structural requirements, while maintaining consistent connection parameters that ensure structural integrity across all assemblies.
3Force
If a heavy gauge pipe exciter beam is used, then force transmission capability is improved, but device complexity and installation difficulty increases
Solution Approach 1:
The heavy gauge pipe structure is segmented into modular sections that can be handled and installed more easily. Each segment maintains the force transmission capability of the heavy gauge construction through optimized wall thickness and reinforcement, while the modular nature reduces installation complexity by breaking down a single heavy component into manageable pieces.
Solution Approach 2:
The modular segments are designed to nest or connect in a hierarchical manner, with standardized interfaces that simplify assembly. This nesting approach allows the complex force transmission structure to be built from simpler, standardized components rather than requiring installation of a single complex heavy gauge pipe assembly.
