Grill Ratchet Coupling for Multi-Position Upper Unit Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grill devices lack the ability to make fine adjustments in the position of the upper grill unit relative to the lower grill unit, limiting user control over the coverage and exposure of the grill surfaces.
Innovation Solution
A coupling mechanism comprising a connection base, a lever, a first and second seat member, and a ratchet unit with interlocking teeth, allowing for precise adjustment and retention of the upper grill unit's position relative to the lower grill unit through a combination of rotational and translational movement, facilitated by a resilient component and an adjustment knob.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional grill device uses a simple hinge connection between upper and lower grill units, then the device structure remains simple, but the upper grill unit cannot be retained at multiple positions and fine adjustment is not possible
Solution Approach 1:
The coupling mechanism is segmented into distinct functional components: a ratchet unit with multiple engagement positions, a latch mechanism with movable and fixed arms, and a coupling member. This segmentation allows the upper grill unit to be retained at multiple discrete positions (first, second, and third positions) while maintaining a manageable overall structure.
Solution Approach 2:
The latch mechanism acts as an intermediary between the user's manual input and the upper grill unit's position retention. The movable latch arm engages with the coupling member at specific engagement positions, providing controlled retention without requiring complex locking mechanisms or multiple fasteners.
2Reliability
If no position retention mechanism is used, then the device structure remains simple, but the upper grill unit cannot be held at selected positions
Solution Approach 1:
The ratchet unit is pre-configured with multiple engagement positions and the latch mechanism is designed to automatically engage at these predetermined positions. This preliminary arrangement ensures that when the user adjusts the upper grill unit, it will be reliably retained at the intended position without requiring additional active retention components.
Solution Approach 2:
The latch mechanism provides self-service position retention through its automatic engagement design. The movable latch arm naturally engages with the coupling member at the engagement positions, providing reliable position holding without requiring continuous user intervention or complex external locking mechanisms.
3Adaptability or versatility
If fine position adjustment is not provided, then the device structure remains simple, but user control over coverage and exposure is limited
Solution Approach 1:
The coupling mechanism transitions from a static fixed-position connection to a dynamic multi-position system. The upper grill unit can be manually moved between first, second, and third positions relative to the lower grill unit, with the latch mechanism providing retention at each position. This dynamic capability allows users to adjust coverage and exposure based on different cooking requirements.
Solution Approach 2:
The system changes the positional parameter of the upper grill unit relative to the lower grill unit. By providing discrete engagement positions that allow the upper grill unit to be positioned at different heights and orientations, the system enables varied cooking configurations such as full coverage, half-open, or fully opened positions, thereby increasing adaptability for different cooking scenarios.

AI summary
A grill device includes a coupling mechanism having first and second ratchet teeth that cooperate to permit movement of an upper grill unit in a first direction for uncovering a lower grill unit, and to resist movement of the upper grill unit relative to the lower grill unit in a second direction opposite to the first direction.
