Solution Overview
Problem
HVAC systems often face challenges in installation and maintenance due to the difficulty of accessing actuatable devices in cramped and poorly illuminated spaces, such as behind industrial equipment or within building structures.
Innovation Solution
A shaft adaptor is designed to mechanically couple an output drive member of an actuator with an input drive member of a component, featuring a housing with interconnected plates, inner and outer jaws, and a clamping mechanism, allowing for easier installation and maintenance by forming an interference fit and enabling rotational movement alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If actuatable devices are installed in tight spaces behind equipment or within structures, then space utilization is improved, but accessibility for installation and maintenance deteriorates
Solution Approach 1:
The connector is divided into multiple segments including a first portion with a first jaw, a second portion with a second jaw, and an intermediate section. This segmentation allows the connector to be assembled in tight spaces by connecting components separately and then joining them through the adapter, making installation and maintenance feasible in confined areas where complete assembly would be impossible.
Solution Approach 2:
The adapter serves as an intermediary component that couples the output drive member of an actuator to the input drive member of a valve. This intermediate element enables connection between components that cannot be directly coupled due to spatial constraints, facilitating installation and maintenance in tight spaces by providing a flexible connection interface.
2Reliability
If a secure connection is formed between actuator and component, then reliability is improved, but device complexity increases
Solution Approach 1:
The connector incorporates movable jaws that can be positioned and secured through a clamping mechanism. The first jaw and second jaw are capable of movement to engage with the drive members, providing a secure dynamic connection that adapts to slight variations in component dimensions while maintaining reliability without requiring overly complex fixed structures.
Solution Approach 2:
The clamping mechanism replaces complex multi-step mechanical fastening systems with a simpler clamping action. By using jaws that can be clamped onto the drive members, the design achieves secure connections without requiring bolts, nuts, or multiple fastening operations, thereby reducing overall device complexity while maintaining connection security.

AI summary
A low profile shaft adaptor for coupling an output drive member of an HVAC actuator with an input drive member of a valve. The shaft adaptor may include a clamp for selectively clamping onto the input drive member of the valve, a drive interface configured to form an interference fit with an output drive member of the HVAC actuator, and a bracket configured to mechanically couple the drive interface and the clamp such that rotational movement of the drive interface by way of the interference fit with the output drive member of the HVAC actuator causes corresponding rotational movement of the clamp and thus the input drive member of the valve.
