Cooler Box Binding Frame Assembly to Reduce Manufacturing Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cooler box manufacturing methods are inefficient due to the difficulty in securely connecting the outer shell, insulation layer, and inner shell during assembly, leading to increased assembly time and reduced productivity.
Innovation Solution
A cooler box design featuring a body portion with a binding frame made of elastic material that clamps the outer and inner shells, along with a hinge structure for the cover portion, allowing for easier assembly and secure fixation of the insulation layer between the shells, and a manufacturing method involving vacuum forming and assembly steps to reduce assembly time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the outer shell, insulation layer, and inner shell are sewn together using traditional methods, then the components can be connected, but the assembly time is excessive and productivity is reduced
Solution Approach 1:
The patent replaces the traditional sewing mechanism with a binding frame assembly system. The binding frame, made of elastic material, mechanically clamps and secures the outer shell, insulation layer, and inner shell together through elastic deformation and friction, eliminating the need for sewing operations and significantly reducing assembly time
Solution Approach 2:
The patent changes the physical state of the binding frame material from rigid to elastic. The elastic material can deform during assembly to accommodate the components and then maintains continuous clamping pressure to secure them together, enabling faster assembly compared to rigid fastening methods
2Reliability
If the components are held firmly during sewing to prevent dislocation, then connection stability is improved, but the operation complexity increases due to requiring two-handed gripping
Solution Approach 1:
The binding frame performs self-service by automatically clamping and securing the components during assembly. The elastic deformation of the binding frame material creates self-adjusting clamping pressure that maintains component stability without requiring manual gripping or positioning by workers
Solution Approach 2:
The binding frame transitions from a rigid structure to a dynamic elastic structure that can deform and adapt during assembly. This dynamic behavior allows the binding frame to automatically adjust to component positions and maintain secure connection without requiring precise manual alignment

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 improved assembly method significantly reduces the time required to manufacture cooler boxes, enhancing production efficiency by securely fixing the insulation layer and ensuring the components are firmly connected without the need for rework.
Implementation Method 1
the binding frame is made of an elastic material, such that the inner and outer clamping wall portions of the binding frame are deformable to move away from each other when the binding frame is assembled to the upper end of the body portion around the storage opening
Implementation Method 2
The cover portion is pivotally turnably connected to the body portion via a hinge structure

AI summary
A cooler box includes a body portion and a cover portion pivotally turnably connected to each other via a hinge structure. The body portion has a storage opening and internally defines a storage space communicable with the storage opening; and includes, from an outer to an inner side, an outer shell, an insulation layer and an inner shell. The body portion further includes a binding frame assembled to an upper end thereof. The binding frame includes two substantially parallelly extended clamping wall portions, which together inwardly clamp on the outer shell, the insulation layer and the inner shell, such that the insulation layer is fixedly held in an enclosed space defined in between the binding frame, the outer shell and the inner shell. With the binding frame, different components of the cooler box can be more easily assembled together to reduce the assembling time and increase the productivity.
