Lever-Clip Cot Structure for Easy Assembly and Lower Pack Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cots with X-shaped legs face limitations in reducing volume and weight due to their length and material requirements for stability, and require significant force for assembly and disassembly.
Innovation Solution
A cot design featuring horizontal poles, support bars with clips that open outward, and a clip adjusting mechanism using a lever principle, allowing for easier assembly and disassembly, reduced weight, and integration of a heating pad for warmth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the legs are made long to maintain stability, then the stability is improved, but the weight and volume increase
Solution Approach 1:
The legs are designed to be collapsible and extendable, allowing the cot to transition between a compact state for transport and a stable extended state for use. This dynamic structure enables stability when needed while minimizing weight and volume during storage.
Solution Approach 2:
The legs are designed to nest within each other when collapsed, with inner leg sections fitting inside outer leg sections. This nesting arrangement significantly reduces the overall volume and weight when the cot is disassembled for transport.

3Ease of manufacture
If the connection rods are pulled to both sides to insert into the guide, then the assembly is completed, but much force is required
Solution Approach 1:
The connection mechanism utilizes spring-loaded clips that automatically engage with the guide slots when the legs are positioned. The springs provide the necessary force to snap the clips into place, eliminating the need for users to apply significant manual force during assembly.
Solution Approach 2:
Spring-loaded clips serve as intermediaries between the connection rods and the guide slots. These clips facilitate easy connection by using spring force to automatically engage with the guides, reducing the manual effort required by users.
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 design reduces the cot's weight and volume, simplifies assembly, and provides warmth through the heating pad, enhancing user convenience and comfort.
Implementation Method 1
the clip adjusting member is configured so that a length at one side extending from the rotary shaft to the clip is shorter than a length at the other side extending from the rotary shaft to an end opposite to the clip, thereby operating by means of the principle of the lever
Implementation Method 2
a heating pad disposed at a lower side of the cloth
