Self-Contained Door-Embedded Information System for Cold Storage Rooms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for temperature rooms with information systems are complex to install, require trained personnel, and can cause cold bridges due to cable routes through insulation walls, leading to inefficiencies and increased sealing efforts, especially in environments where the interior atmosphere needs to be separated from the external atmosphere.
Innovation Solution
A self-contained information system with a housing unit embedded in the door of the temperature room, featuring a network-independent electrical supply, energy-saving signal providers, and a control unit that ensures a power storage supply for at least one year, allowing for easy assembly and operation without connecting to the building's electricity network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If cable routes are created through insulation walls to connect information systems to the building electricity network, then the system can be powered by the building's electricity network, but cold bridges are caused that lower the efficiency of the temperature room
Solution Approach 1:
The information system is extracted from the temperature room interior and placed in the door structure outside the temperature room. This allows the system to be powered by the building electricity network through the door without creating cable routes through the insulation wall, thereby eliminating the cold bridge problem while maintaining electrical power supply capability
Solution Approach 2:
The door structure serves as an intermediary between the temperature room and the building electricity network. By positioning the information system in the door, the door acts as a mediator that provides electrical power access without requiring penetration of the insulation wall, thus avoiding thermal loss
2Adaptability or versatility
If multiple separate information systems are installed for different functions (emergency call, temperature monitoring, door status), then comprehensive monitoring is achieved, but the installation complexity and number of cable routes increase
Solution Approach 1:
Multiple information system functions (emergency call button, temperature monitoring, door status monitoring) are merged into a single integrated system housed in the door structure. This consolidation reduces the number of separate installations and cable routes while maintaining comprehensive monitoring capabilities across all functions
Solution Approach 2:
The information system in the door is designed with multi-functionality, serving as an emergency call system, temperature monitoring system, and door status monitoring system simultaneously. This universal design eliminates the need for multiple separate systems and their associated installation complexities
3Reliability
If personal emergency call systems with TAST switches and signal units are installed, then emergency communication capability is provided, but trained electrical installers are required for connection to the house electricity network
Solution Approach 1:
The information system is extracted from the temperature room interior and positioned in the door structure, which is accessible during door assembly. This allows the system to be installed by the door manufacturer without requiring trained electrical installers to penetrate insulation walls and connect to the building electricity network, while maintaining emergency call functionality
