Solution Overview
Problem
Existing cooling collars using phase change materials or gel materials have limited cold storage capacity and require natural or refrigeration-based recharging, while those using refrigeration sheets suffer from low cooling efficiency and skin irritation due to metal shells.
Innovation Solution
A refrigerable hanging ice neck collar with an elastic neck collar bracket, heat dissipation component, refrigeration sheet, non-metallic shell, cold storage material layer, and electronic control component, which includes a fan to enhance cooling efficiency and a cold storage material layer to maintain cooling over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If refrigeration sheets are used for cooling, then cooling function is provided, but cooling efficiency is low when heat accumulates
Solution Approach 1:
The patent introduces a cold storage material layer as an intermediary between the refrigeration sheet and the user's neck. This layer absorbs and stores cold energy from the refrigeration sheet, then releases it gradually to maintain cooling efficiency even when the refrigeration sheet itself accumulates heat and its cooling capacity diminishes.
Solution Approach 2:
The cold storage material layer utilizes phase change properties to absorb and release thermal energy. When the refrigeration sheet cools the material layer, the material undergoes phase transition (e.g., from liquid to solid or from less ordered to more ordered molecular arrangement), storing cold energy. Later, during phase change back, it releases this stored cold energy to maintain cooling effect.
2Strength
If metal shells are used for structure, then structural strength is provided, but skin irritation occurs
Solution Approach 1:
The patent replaces the traditional metal shell with a flexible non-metallic shell that conforms to the user's neck contour. This flexible shell provides sufficient structural strength and comfort while eliminating the skin irritation caused by rigid metal surfaces, allowing close contact with the skin without discomfort.
3Quantity of substance
If phase change materials or gel materials are used as fillers, then cold storage is achieved, but cold storage capacity is limited and recharging requires natural or refrigeration methods
Solution Approach 1:
The patent introduces a refrigeration sheet as an active intermediary cooling device that directly contacts the cold storage material layer. This refrigeration sheet can be electrically powered to actively freeze or cool the material layer, dramatically reducing recharging time compared to passive natural cooling or refrigerator-based recharging methods.
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
Enhances continuous cooling capacity, reduces skin irritation, and maintains cooling effect through a non-metallic shell and cold storage material layer, improving user comfort and reducing energy consumption.
Implementation Method 1
This collar product absorbs heat through the contact of the shell with the skin, and transfers the heat to the refrigeration sheet to achieve cooling
Implementation Method 2
the fan is provided at an end of the neck collar bracket and is adjacent to the air inlet of the heat dissipation component. An air outlet direction of the fan is oriented toward the air inlet.

AI summary
Disclosed is a refrigerable hanging ice neck collar, which includes a neck collar bracket, a heat dissipation component, a refrigeration sheet, a fan, a non-metallic shell, a cold storage material layer and an electronic control component. The neck collar bracket and the non-metallic shell are respectively elastic, and the electronic control component is used to control the cooling of the refrigeration sheet and the rotation of the fan. The fan rotates to supply air into the air duct, and the through hole in the air duct is used to connect the heat dissipation component. When the wind in the air duct passes through the through hole, it will take away part of the heat of the refrigeration sheet and dissipate heat and cool the refrigeration sheet, and the air outlet can also provide airflow to blow toward the head.
