Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceramic grill hinge structures face issues with stress concentration, limited movable range, uneven stress distribution, and installation difficulties due to complex designs and double spring mechanisms, which can lead to deformation or fracture, and pose safety risks during use.
Innovation Solution
A new ceramic grill hinge structure featuring a single spring, embedded upper cover, non-penetrating connecting shaft, and triangularly arranged connecting holes, with a safety nut and adjusting mechanism to allow for adjustable elastic force, enhancing stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a double shaft and double spring hinge structure is used, then the grill cover can stay at any angle and sealing effect is improved, but the device complexity increases and installation becomes difficult
Solution Approach 1:
The patent extracts and removes one shaft and one spring from the traditional double shaft-double spring hinge structure, simplifying it to a single shaft-single spring configuration. This extraction maintains the essential functionality of angle adjustment and suspension stability while significantly reducing structural complexity and installation difficulty.
Solution Approach 2:
The patent merges the functions of multiple components into a more integrated single shaft structure. The single shaft combines the rotational support and positioning functions, while the single spring provides the necessary elastic force for angle adjustment, consolidating what were previously separate dual components into a unified simpler system.
2Adaptability or versatility
If arcuate grooves are provided in the hinge structure, then the movable range is improved, but stress concentration occurs and the structure becomes prone to deformation or fracture
Solution Approach 1:
The patent replaces the traditional arcuate grooves with a spherical bearing structure. The spherical geometry provides the necessary movable range and angular adjustment capability while distributing stress uniformly across the spherical surface, eliminating the stress concentration points that occur at the curved groove transitions.
3Adaptability or versatility
If adjusting ears with multiple holes are provided, then the adaptability to different grill sizes is improved, but the stress distribution becomes uneven and deformation occurs
Solution Approach 1:
The patent segments the adjusting mechanism into a modular design where the single shaft with threaded portion allows incremental adjustment while maintaining structural integrity. Instead of multiple holes in ears that create weak points, the threaded adjustment provides continuous, uniform stress distribution throughout the adjusting component.
4Object-affected harmful factors
If a non-penetrating connecting shaft design is used, then the safety risk is reduced and installation is simplified, but the connection reliability may be compromised
Solution Approach 1:
The patent uses a nested design where the single shaft is received within a housing or cover structure. The shaft extends into the connecting components but is contained within a protective enclosure, eliminating exposed sharp edges and safety hazards while maintaining secure mechanical connection through the nested interface.
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 new hinge structure improves the ceramic grill's usability by allowing the top cover to suspend at any angle, reducing the risk of accidental falls, and adapting to different grill weights, while simplifying installation and reducing the risk of injury.
Implementation Method 1
an elastic member (19), wherein one end of the elastic member (19) is pressed against the adjusting member (18), and the other end of the elastic member (19) is pressed against the hinge lower cover (2)
