Pressure Activated Recharging Cooling Platform

What is this patent about?

’685 is related to the field of temperature regulation, specifically cooling platforms designed for animals. The background highlights the limitations of existing pet beds, which often rely on centralized cooling plates requiring electrical power or ice packs that need frequent replacement. This creates a need for a portable, user-friendly, and non-electric cooling solution for pets, especially during post-surgery recovery or other conditions requiring temperature regulation.

The underlying idea behind ’685 is to create a pressure-activated cooling system that utilizes an endothermic reaction to absorb heat when pressure is applied and an exothermic reaction to release heat when pressure is removed. This allows the cooling platform to recharge itself without external power or refrigeration, making it a portable and reusable solution. The key is a specific chemical composition that responds reversibly to pressure changes, driving the cooling and recharging cycles.

The claims of ’685 focus on a cooling platform featuring a temperature regulation layer containing a cooling composition. This composition absorbs heat upon activation (through applied pressure) and releases heat upon deactivation (removal of pressure). The platform is designed for repeated activation and deactivation cycles. Claim 20 further specifies the physical structure, including angled segments within the temperature regulation layer, a support layer, and a covering layer.

In practice, the cooling platform works by having an animal (or other object) apply pressure to the surface. This pressure triggers an endothermic reaction within the cooling composition, causing it to absorb heat from the object and provide a cooling effect. When the animal moves or the pressure is removed, the reaction reverses, releasing the absorbed heat and 'recharging' the cooling platform for the next use. The angled segments and channels within the temperature regulation layer help to distribute the cooling composition and prevent it from being displaced under pressure.

The differentiation from prior approaches lies in the pressure-activated, self-recharging mechanism . Unlike electric cooling plates or ice packs, this platform doesn't require external power or manual replacement of cooling elements. The specific composition of carboxymethyl cellulose, water, polyacrylamide, and alginic acid allows for a sustained cooling effect and efficient recharging. The design, including the channeled covering layer, also aids in air circulation and heat transfer, enhancing the overall cooling performance.
