Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oven doors that open parallel to the ground plane occupy too much space when fully open, making it difficult to reach the cooking volume, and synchronous double-door ovens fail to provide proper sealing and alignment.
Innovation Solution
The oven design features two doors that open synchronously on a perpendicular axis, utilizing guide levers and a motion control group with flexible elements and stoppers to maintain sealing and prevent door collision, allowing for simultaneous opening and closing while ensuring proper alignment and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the oven door opens on an axis parallel to the ground plane, then the door can be fully opened for access, but it occupies too much space and makes it difficult to reach the cooking volume in narrow kitchens
Solution Approach 1:
The patent changes the door opening direction from horizontal (parallel to ground plane) to vertical (perpendicular to ground plane). This dimensional change allows the door to open upward instead of outward, significantly reducing the space occupied by the door when fully open while maintaining full access to the cooking volume inside.
2Ease of operation
If synchronous double-door opening mechanism is implemented, then simultaneous opening with one hand is enabled, but sealing and proper fitting between doors cannot be provided
Solution Approach 1:
The patent introduces a coupling assembly with spur gears as an intermediary mechanism between the two doors. This gear-based coupling ensures that when one door is opened, the other door is simultaneously opened through mechanical engagement, while also providing a means to press the doors against the gasket for proper sealing.
Solution Approach 2:
The patent changes the physical state or condition of the door system by using the spur gear mechanism to apply force that presses the doors against the gasket. This parameter change (applying contact force) ensures proper sealing while maintaining the synchronous opening function.
3Ease of operation
If coupling assembly with spur gear is used to enable synchronous opening, then simultaneous door operation is achieved, but the mechanism becomes complex and may interfere with door movement
Solution Approach 1:
The coupling assembly with spur gears is designed to automatically engage and disengage based on the door movement itself. When the doors move, the gears self-engage to provide synchronous operation and self-disengage when not needed, eliminating the need for additional control mechanisms and reducing overall system complexity.

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 enables efficient use of space by allowing synchronous operation of oven doors, minimizing the risk of door collision and ensuring proper sealing, even in narrow kitchen environments.
Implementation Method 1
a flexible element, one end of which is mounted to the connection group and the other end to the main body, which ensures sealing by applying force to the doors
