Heat Pump Water Heater Venting Tabs for Tool-Free Conduit Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat pump water heaters lack a convenient method to attach external venting conduit to the air inlet and outlet, limiting the ability to draw ambient air from a different location and vent discharge air away from the unit.
Innovation Solution
The integration of bendable tabs on the air inlets and outlets of the heat pump water heater housing allows for the bending of these tabs to form a channel, enabling the secure attachment of external venting conduits without the need for cutting or additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional heat pump water heater designs are used, then the structure is simple and manufacturing is easy, but the ability to attach external venting conduit is limited
Solution Approach 1:
The air inlet and outlet are segmented into multiple separate tabs instead of a single continuous flange. Each tab can be independently bent and positioned, allowing the conduit to be attached at various locations and angles, thereby improving adaptability while keeping each individual tab simple in structure
Solution Approach 2:
The tabs are designed to be bendable rather than fixed, allowing users to adjust the tab positions to match different conduit orientations. This dynamic feature enables versatile attachment configurations without requiring complex pre-fabricated adapters or multiple hardwired options
2Ease of operation
If conventional attachment methods are used, then additional hardware and cutting are avoided, but the convenience of attaching venting conduit is limited
Solution Approach 1:
The bendable tabs themselves serve as both the attachment mechanism and the connecting element. Users simply bend the tabs into position and secure the conduit directly to them, eliminating the need for separate clamps, brackets, or cutting operations. The structure serves its own attachment function without requiring additional hardware
Solution Approach 2:
The tabs are pre-formed as integral parts of the air inlet/outlet housing, positioned and sized in advance to facilitate easy conduit attachment. This preliminary preparation allows users to simply bend and attach without needing to perform complex fabrication or modification work on-site
