Heating Device Door Hinge for Tilt-Open Without Intermediate Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing doors for heating devices with solid fuel, such as tiled stoves, are complex in design and require an intermediate frame for operation, which is not robust enough to withstand high thermal loads and simplify the design while ensuring functionality.
Innovation Solution
The door mechanism uses actuating elements that interact with connecting rods to lock and unlock hinge parts, eliminating the need for an intermediate frame by allowing or blocking movement based on the desired opening action, with push rods and eccentric mechanisms to control tilting and opening movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an intermediate frame is used to enable door opening and tilting movements, then the door can achieve multiple opening positions, but the device complexity increases and robustness under thermal loads decreases
Solution Approach 1:
The patent removes the intermediate frame from the door structure, eliminating the complex multi-component assembly. The door leaf is directly hinged to the door frame, extracting the unnecessary intermediate element while maintaining the ability to perform opening and tilting movements through the hinge mechanism alone.
Solution Approach 2:
The patent combines the functions of the intermediate frame and the hinge mechanism into a single integrated hinge system. The hinge directly connects the door leaf to the door frame, merging the support and movement-control functions that were previously separated between the intermediate frame and hinges.
2Ease of operation
If an intermediate frame is used for door operation, then the door can be opened and tilted, but the thermal load resistance and durability are insufficient
Solution Approach 1:
The intermediate frame is removed from the structure, eliminating the component that proved insufficient for withstanding thermal loads. The door system now relies on the more robust direct hinge connection to the main door frame, which is designed to withstand the high thermal environment.
Solution Approach 2:
The door frame and hinge components are designed using materials and construction methods suitable for high-temperature environments, ensuring that the remaining structural elements can withstand thermal loads while maintaining operational functionality.
3Adaptability or versatility
If an intermediate frame is used to control door movements, then the door can achieve desired opening actions, but the design becomes unnecessarily complex
Solution Approach 1:
The intermediate frame is extracted from the door assembly, simplifying the manufacturing process. The door leaf is directly attached to the door frame via hinges, eliminating the need to manufacture, assemble, and maintain a separate intermediate frame structure.
Solution Approach 2:
The manufacturing processes for the door frame and door leaf are simplified by eliminating the intermediate frame. The direct hinge connection reduces the number of parts to be manufactured and assembled, making the overall door structure easier to produce.

AI summary
The door has a doorframe (1) that is provided with a glass panel (2) that is provided with hinges (5,6,8,9) that is provided along a lower horizontal axis (4) and is tilted along vertical axis (7). The actuating elements (11,21) are provided in pushrods (15,25) in the position in which the hinge is latched with the doorframe and in the position in which the hinge is disengaged from the doorframe. The pushrods are arranged perpendicular to the doorframe. The inner end of actuating element is engaged into a driver.
