Solution Overview

Problem

Existing thermally insulated containers fail to maintain temperature-sensitive goods within predetermined ranges due to unpredictable ambient temperatures, movement of PCM units during transit, and potential theft risks, leading to product degradation and health hazards.

Innovation Solution

A thermally insulated container with a mounting system that secures PCM units to the opening member, using a pivotally attached locking member to restrain their movement and ensure predictable temperature control, thereby preventing temperature deviations and theft.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If PCM units are placed freely in the container, then the container is easy to load and simple in structure, but the PCM units move during transportation causing temperature control failure

Engineering Contradiction:
Improvetemperature control reliabilityVSAvoidmounting structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The container interior is segmented into functional zones using mounting structures attached to specific surfaces (side walls, end walls, opening member). These structures create designated positions for PCM units, separating them from free movement while maintaining organizational simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Mounting structures are pre-attached to the container walls and opening member before PCM units are loaded. This preliminary preparation ensures that when PCM units are placed, they are immediately positioned and restrained in predetermined locations, preventing movement during transport.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If PCM units are restrained to predetermined positions, then temperature control is improved, but the mounting structure becomes more complex

Engineering Contradiction:
Improvetemperature range maintenanceVSAvoidmounting assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The restraining function is segmented across multiple simple components distributed on different container surfaces. Rather than one complex centralized mechanism, simple mounting structures are distributed on side walls, end walls, and the opening member, each handling local PCM unit restraint.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting structures serve multiple functions: they position PCM units in predetermined locations, restrain them during transport, and can be implemented on various container surfaces (side walls, end walls, opening member) using similar simple attachment methods.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If the container is opened frequently for monitoring, then temperature control can be adjusted, but the risk of theft increases

Engineering Contradiction:
Improvetemperature monitoring capabilityVSAvoidtheft risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Temperature monitoring is achieved through remote sensing capabilities that provide feedback on internal conditions without requiring physical container opening. This allows continuous temperature verification while maintaining container security and preventing theft opportunities.

Inventive Principle:
Principle #23Feedback

4Productivity

If PCM units are mounted on the opening member, then space utilization is improved and mounting is quick, but the structure must support additional weight

Engineering Contradiction:
Improvemounting speedVSAvoidopening member load capacity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The weight load is segmented and distributed across multiple attachment points on the opening member rather than concentrated at single locations. This distribution of mechanical stress allows the opening member to support PCM units effectively while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation
