Oven Door Hinge Counterweight and Damper for Slam Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ovens lack mechanisms to control the motion or speed of the door, leading to slamming issues and inadequate handling of high stress loads, particularly in the food service industry where doors need to withstand significant weight and frequent use.
Innovation Solution
The oven design incorporates a frame with counterweights and dampers to control the door's motion, using a pair of hinges with counterweights and dampers positioned on opposing sides to resist movement, ensuring the door opens and closes smoothly and safely, even under heavy loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional ovens use simple door hinges without counterweights or dampers, then the device complexity is low, but the door cannot handle high stress loads and may slam during operation
Solution Approach 1:
The patent applies counterweights coupled to the door assembly that offset the weight of the door, reducing the stress on hinges and improving the door's ability to handle high loads without slamming during operation
Solution Approach 2:
The patent introduces dampers as intermediary elements between the door and frame that control door movement and reduce slamming, thereby protecting the door mechanism while maintaining structural integrity
2Reliability
If traditional ovens lack door motion control mechanisms, then the ease of operation is high, but the door may slam and cause safety issues under heavy use
Solution Approach 1:
The patent introduces dampers as intermediary elements between the door and frame that control door movement and reduce slamming, thereby protecting the door mechanism while maintaining structural integrity
Solution Approach 2:
The dampers provide beforehand cushioning by resisting door movement in controlled directions, preventing slamming before it occurs and ensuring reliable operation under heavy use conditions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution prevents the door from slamming and allows it to operate reliably under heavy loads, enhancing safety and durability, particularly suitable for the food service industry.
Implementation Method 1
a pair of counterweights that are each coupled to the rear portion of a respective hinge
Implementation Method 2
a pair of dampers, each damper coupled to the frame and operable to resist movement of the door
Implementation Method 3
each damper being operable to resist movement of the door in a single direction opposite that of the other damper

AI summary
According to one embodiment, an oven includes an oven chamber operable to be heated and having a front opening. The oven further includes a frame coupled to and at least partially surrounding the oven chamber. The oven further includes a door operable to seal the front opening of the oven chamber, and a pair of hinges pivotally coupling the door to the frame. Each hinge is positioned on opposing sides of the oven chamber. The oven further includes a pair counterweights that are each coupled to the rear portion of a respective hinge, and a pair of dampers. Each damper is coupled to the frame and operable to resist movement of the door in a single direction opposite that of the other damper.
