Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional ice cubes or simple cold packs are used, then the cold pack is easy to manufacture and lightweight, but the temperature stability is poor and condensation forms quickly
Solution Approach 1:
The patent uses a composite formulation combining polyacrylamide, water, and aloe vera gel to create a cold pack that maintains temperature stability while reducing condensation. The polyacrylamide provides structural stability and temperature maintenance, aloe vera gel reduces condensation through its hygroscopic properties, and water serves as the cooling medium.
Solution Approach 2:
The patent modifies the chemical and physical parameters of the cold pack formulation by adjusting the ratios of polyacrylamide, water, and aloe vera gel. By optimizing these parameters, the cold pack achieves extended temperature stability and reduced condensation while maintaining ease of manufacture.
2Duration of action of moving object
If chemicals are added to extend the cold period, then the duration of action is improved, but the device complexity increases
Solution Approach 1:
The cold pack formulation is designed to be self-regulating, where the polyacrylamide and aloe vera gel work together to maintain temperature stability and reduce condensation without requiring external chemical additives or complex mechanisms. The system serves itself by utilizing the inherent properties of the materials.
3Stability of the object's composition
If the cold pack uses heavy materials for temperature stability, then the temperature stability is improved, but the weight increases causing pressure on the body
Solution Approach 1:
The patent changes the density and compositional parameters of the cold pack by using a formulation of polyacrylamide, water, and aloe vera gel. This creates a lightweight yet stable cold pack that maintains temperature without the heavy materials traditionally used, thereby reducing pressure on the body while preserving temperature stability.
