Collapsible Campfire Grill Stand With Adjustable Height and Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing campfire grilling devices are often bulky, unsuitable for varying cooking needs, and pose safety hazards due to fixed positions and limited space, with built-in grates being frequently damaged or unsanitary, and lacking adjustable height and easy food handling.
Innovation Solution
A portable, collapsible grill stand with a center column assembly of pivotable vertical members and adjustable grill height, featuring a gripper mechanism for easy assembly and disassembly, allowing for flexible positioning and storage, and a set screw mechanism for stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a built-in grate is provided in permanent grill fixtures, then cooking can be performed, but the position and height are fixed which limits adaptability for different cooking needs
Solution Approach 1:
The patent implements a telescopic pole assembly that allows the grill support surface to be adjusted to various heights and positions. The poles can extend and retract, and the support surface can be tilted to different angles, transforming the static built-in grate into a dynamic, adjustable structure that adapts to different cooking requirements while maintaining a relatively simple overall design.
2Reliability
If built-in grates are used in outdoor fixtures, then cooking is enabled, but they are frequently damaged or unsanitary due to repeated use without cleaning
Solution Approach 1:
The grill support surface is designed as a separate, removable component that can be detached from the telescopic pole assembly. This segmentation allows the support surface to be easily removed for cleaning or replacement, preventing accumulation of grime and damage from repeated use. The modular design enables maintenance without affecting the entire grill structure.
3Area of stationary object
If a fixed built-in grate is provided, then cooking space is available, but there is too little space for large groups and food placement is difficult and dangerous
Solution Approach 1:
The support surface is designed to be tiltable and adjustable, allowing users to tilt it forward to access food on the fire or slide it forward to place food safely without leaning over flames. The telescopic poles enable the support surface to be positioned at optimal heights for both cooking capacity and user safety, accommodating large groups with extended cooking area.
4Stability of the object's composition
If vertical members are made rigid for stability, then the structure is strong, but it cannot be folded for portable storage
Solution Approach 1:
The vertical members incorporate telescopic sections that can extend to provide rigid, stable support during grilling, then retract and nest within each other for compact storage. The members maintain structural integrity when extended through interlocking telescopic mechanisms, yet can be collapsed to a fraction of their extended length, achieving both stability during use and portability for storage without significantly increasing weight.

AI summary
The foldable Sportsman EZ grill is described. The Sportsman EZ portable grill has a grill member and a frame. The frame supports the Sportsman EZ grill on a support surface, keeping the front legs away from the fire/heat source, extending outwardly and in an arch from the frame. The support arms have a distal end and a proximal end. The distal end is joined to the support structure which connects to the grill member.
