Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sensors are mounted in refrigerated containers using existing methods, then monitoring of environmental parameters is achieved, but sensors are prone to damage and difficult to repair or replace

Engineering Contradiction:
Improvesensor durabilityVSAvoidsensor replacement difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The sensor system is divided into separate modular components: a sensor module with sensing elements and a battery module with power supply. These modules can be independently replaced, allowing damaged sensors to be swapped without replacing the entire system, thereby improving repair ease while maintaining reliability through modular protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting system transitions from fixed rigid attachment to a dynamic removable interface using conductive adhesive pads and electrical contacts. This allows the sensor modules to be easily detached and reattached, facilitating quick replacement and repair while maintaining reliable electrical connections during operation.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If traditional sensor systems are used in refrigerated containers, then environmental monitoring is provided, but the systems lack flexibility and modularity

Engineering Contradiction:
Improvesystem flexibilityVSAvoidsystem modularity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sensor system is segmented into independent functional modules (sensing elements, battery, housing) that can be separately configured and replaced. This modular architecture provides flexibility for different monitoring requirements while simplifying the overall system through standardized interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The battery housing serves multiple functions: it contains the power supply, provides structural support, and includes mounting features for attachment to container surfaces. This multi-functionality reduces the number of separate components needed, achieving versatility without proportionally increasing complexity.

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