Oven Door Lock with Incremental Opening for Pyrolysis Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pyrolysis-capable baking ovens lack functionality in their door locking mechanisms, offering limited options for door positioning and operation.
Innovation Solution
A pyrolysis-capable baking oven with a door lock that includes a movable locking device with a locking hook, accommodated on a lock housing, allowing the door to be opened and closed incrementally, featuring a spring-biased hook housing, a coupler for motor-controlled movement, and switches for position detection, enabling various operational states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door lock uses a fixed locking mechanism, then the structure is simple, but the door cannot be opened incrementally
Solution Approach 1:
The locking device is designed to be movable between a retracted position (allowing door opening) and an extended locked position (securing the door closed). This dynamic positioning capability enables the door to be opened incrementally while maintaining structural simplicity through controlled movement rather than complex multi-component mechanisms
2Ease of operation
If the locking device is extended to lock the door, then the door is securely locked, but the door cannot be opened
Solution Approach 1:
The locking device operates in periodic cycles between locked and unlocked states. During operation, the control unit periodically extends the locking device to secure the door, then retracts it to allow opening when needed. This periodic action ensures both secure locking when required and easy opening when the cycle calls for it
3Ease of operation
If the locking device is retracted to allow door opening, then the door can be opened, but the door is not securely locked
Solution Approach 1:
The system incorporates switches that detect the position of the locking device and provide feedback to the control unit. This feedback mechanism ensures the door is properly locked when the locking device is extended and safely opens when retracted, maintaining both security and operational ease through automated position verification
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 oven door can be easily opened and closed incrementally, providing more operational flexibility and safety features, such as automatic opening and locking, with enhanced user control and program integration.

AI summary
Cooking appliance (1), such as an oven capable of pyrolysis, with a lock latch (2) and with a lock latch (2) and with a door lock (3), which are each mounted on one of two opposing components (4, 5) of the cooking appliance (1), one component being designed as an appliance housing (4) and one component being designed as an appliance door (5), and the appliance door (5) being arranged such that the appliance door (5) can move relative to the appliance housing (4). The door lock (3) comprises a lock housing (6) and a locking device (7) with a locking hook (8) for holding the appliance door (5). The locking device (7) is movably accommodated on the lock housing (6) between a closed position (70) and at least one extended position (71). In the extended position (71), the appliance door (5) is open by a gap.
