Stepless Grill Height Locking With Inclined Rail Slider
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grills have limited height adjustment options, leading to inadequate grilling of foods of varying thicknesses, and sliding push buttons often slip and fail to apply consistent compaction.
Innovation Solution
A stepless height-adjustable grill design featuring an inclined rail and lock-up edge system with a slidable height fixing slider and seesaw lever, allowing for continuous height adjustment and secure locking to prevent slipping, along with anti-skidding structures for reliable interlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sliding push buttons with height fixing steps are used, then the grill structure is simple, but the height adjustment is limited to a few fixed positions
Solution Approach 1:
The patent replaces fixed height steps with a dynamic continuous adjustment mechanism. The upper cover component can be adjusted to any position along the inclined rail rather than being limited to discrete steps, enabling stepless height adjustment to accommodate various food thicknesses.
Solution Approach 2:
The patent introduces an inclined rail that provides a continuous dimensional space for height adjustment. Instead of moving between discrete vertical levels, the upper cover component can be positioned at any point along the inclined trajectory, adding positional flexibility.
2Reliability
If sliding push buttons are used without positioning features, then the structure is simple, but the buttons easily slip and fall from height fixing steps
Solution Approach 1:
The locking mechanism operates automatically through spring force. When the upper cover component is positioned on the inclined rail, the spring-driven locking structure engages automatically to secure the position without requiring manual intervention or complex control systems.
Solution Approach 2:
The patent introduces a spring as an intermediary element that provides the locking force. The spring acts as a mediator between the upper cover component and the base, enabling reliable positioning through elastic force rather than complex mechanical interlocking.
3Ease of operation
If fixed height positions are used, then the structure is stable, but it is difficult to adjust the degree of compaction applied by the upper grilling disc onto foods
Solution Approach 1:
The system transitions from static fixed positions to dynamic continuous adjustment. Users can smoothly vary the height of the upper cover component along the inclined rail to precisely control the compaction degree applied to foods, making the adjustment process as easy as sliding the component to the desired position.
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
Enables precise height adjustment and secure locking, ensuring consistent food compaction and meeting diverse grilling needs by allowing the upper grilling disc to be positioned optimally relative to the lower disc for effective heating.
Implementation Method 1
the lock is interlocked with the lock-up edge by means of the spring force of a spring
Implementation Method 2
the lock is a seesaw lever which is connected to the height fixing slider through a pin shaft

AI summary
A stepless height-adjustable grill, an inclined rail is disposed on one side of a base body, and a corresponding connecting rod is provided with a slidable height fixing slider which is positioned on the inclined rail. The inclined rail is provided with a lock-up edge, while the height fixing slider is provided with a lock; when the height fixing slider is positioned on the inclined rail, the lock is interlocked with the lock-up edge by means of the spring force of a spring to position the height fixing slider on the inclined rail. The lock is provided with a release portion which overcomes the spring force of the spring to release the interlocking between the lock and the lock-up edge. The interlocking between the lock and the lock-up edge can be released by operating the release portion, and the upper cover component can be freely lifted by a handle.
