Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotating machinery coupling adapters do not allow for inspection, maintenance, or replacement without removing the motor, posing safety hazards and failing to protect against contaminants like liquids and debris.
Innovation Solution
An adapter with hollow body and longitudinal openings for access, combined with a cover featuring sheet segments and a gasket for sealing, which can be adjusted to fit various sizes and securely attach over the adapter, providing protection and safety during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional exposed couplings are used, then the structure is simple and easy to access, but user safety is compromised due to accidental contact hazards
Solution Approach 1:
The adapter is divided into multiple segments including a hollow body, longitudinal openings for access, and a separate cover assembly. This segmentation allows the coupling to be protected while maintaining access capability, resolving the contradiction between safety and accessibility.
Solution Approach 2:
The adapter acts as an intermediary component between the motor and the coupling guard. It provides a structured interface that enables safe access to the coupling through controlled openings while maintaining overall protection, thus improving safety without excessive complexity.
2Reliability
If coupling guard adapters are used to improve safety, then user safety is improved, but maintenance and replacement require removing the motor which creates safety hazards and increases complexity
Solution Approach 1:
The adapter structure is segmented with longitudinal openings that provide access to the coupling without requiring removal of the entire motor assembly. This allows maintenance personnel to service the coupling safely while the motor remains in place, resolving the contradiction between safety and ease of maintenance.
Solution Approach 2:
The adapter incorporates a removable cover assembly that can be dynamically opened or closed based on maintenance needs. This dynamic feature allows the coupling to be accessible during maintenance while protected during normal operation, improving both safety and ease of operation.
3Ease of operation
If traditional open couplings are used, then access is easy, but the coupling is exposed to contaminants such as liquids and debris
Solution Approach 1:
The adapter employs a hollow body structure with controlled openings rather than complete enclosure. This flexible protection approach shields the coupling from contaminants while maintaining necessary access, resolving the contradiction between accessibility and contaminant protection.
Solution Approach 2:
The adapter serves as an intermediary barrier between the coupling and the external environment. It selectively filters access, allowing necessary maintenance operations while blocking harmful contaminants, thus protecting the coupling without completely isolating it.
4Ease of operation
If the adapter includes longitudinal openings for access, then maintenance is easier, but the structure becomes more complex
Solution Approach 1:
The adapter structure is segmented into functional zones with longitudinal openings strategically positioned to provide access. This segmentation creates a balanced design that offers maintenance accessibility while maintaining overall structural simplicity through purposeful division rather than complex assembly.

AI summary
An adapter for connecting stationary portions of two housing that are connected via a rotatable shaft. The adapter includes a hollow body that extends from a first axial end to a second axial end. A first fastening feature is arranged proximate the first axial end and a second fastening feature is arranged proximate a second axial end. The hollow body has an interior area that extends from a first lateral opening that is located proximate the first axial end to a second lateral opening that is located proximate the second axial end. One or more longitudinal openings are located between the first axial end and the second axial end. The one or more longitudinal openings are configured to access the interior area.
