Solution Overview
Problem
Existing refrigerated cabinets for perishable food delivery are either too bulky and immobile or lack secure, lockable compartment systems, limiting their use in various delivery locations.
Innovation Solution
A foldable and portable refrigerated device with a security-protected opening system, comprising a base with a refrigerating unit, a foldable exterior structure, and a foldable interior structure with compartments, featuring a solenoid or electric lock and a computerized reader for controlled access, allowing for secure storage and adaptation of compartment volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If refrigerated cabinets are made large and bulky to provide secure lockable compartments, then security and storage capacity are improved, but portability and mobility deteriorate
Solution Approach 1:
The refrigerated cabinet is divided into multiple detachable modules including a base module with refrigeration unit, exterior structure modules with insulation, and interior structure modules with compartments. These modules can be connected and disconnected easily, allowing the cabinet to be assembled into a secure lockable configuration for storage and then disassembled for portability and mobility to different delivery locations.
2Ease of operation
If refrigerated cabinets are made foldable to improve portability, then ease of transport is improved, but structural stability and security deteriorate
Solution Approach 1:
The cabinet employs dynamic structural elements including telescopic shelves that can extend and retract, and foldable exterior and interior structures that can be assembled and disassembled. When assembled for use, these dynamic elements provide structural stability comparable to fixed cabinets, while when disassembled they enable easy portability and adaptability to different delivery locations.
3Adaptability or versatility
If refrigerated cabinets are made movable to enable use in different delivery locations, then versatility is improved, but device complexity deteriorates
Solution Approach 1:
The cabinet is designed as a universal system with standardized modules that can be configured for different delivery locations and requirements. The base module with refrigeration unit, exterior structure modules with insulation, and interior structure modules with compartments can be combined in various configurations, providing versatility for mobile use while keeping individual module complexity manageable through standardization.
