Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large quantity of insulating material is used to guarantee effective insulation, then insulation reliability is improved, but production cost increases

Engineering Contradiction:
Improveinsulation reliabilityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The support is divided into multiple functional zones: an open cavity for receiving electronic units, hollow columns for electrical connection elements, and channels for material flow. This segmentation allows insulating material to be strategically placed only where needed (in hollow columns and channels) rather than throughout the entire support structure, reducing total material quantity while maintaining insulation reliability at critical electrical connection points

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design applies insulating material locally within hollow columns and channels where electrical connection elements are positioned, rather than uniformly across the entire support. This localized application ensures effective insulation at critical interfaces between electronic units while minimizing unnecessary material usage in non-critical areas, thereby reducing production costs

Inventive Principle:
Principle #3Local quality

2Reliability

If a large quantity of insulating material is used to guarantee effective insulation, then insulation reliability is improved, but the device size increases

Engineering Contradiction:
Improveinsulation reliabilityVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The support structure is segmented into compact functional elements (open cavity, hollow columns, channels) that are tightly integrated. Insulating material is confined to specific hollow columns and channels rather than filling the entire support volume, enabling effective insulation without increasing overall device size

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hollow columns are nested within the support structure, with insulating material contained within these columns. The channels are integrated into the support body, allowing material to flow through predefined pathways. This nesting approach ensures insulation is provided exactly where needed without adding external volume to the device

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If traditional insulation methods are used, then insulation coverage is improved, but material consumption increases

Engineering Contradiction:
Improveinsulation coverageVSAvoidinsulating material quantity
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The support is segmented into open cavities for electronic units, hollow columns for electrical connection elements, and channels for material flow. This segmentation directs insulating material precisely to hollow columns and channels where electrical connection elements require insulation, eliminating material waste in non-critical areas while ensuring complete coverage at insulation-critical interfaces

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Insulating material is applied locally within hollow columns and channels where electrical connection elements are positioned, rather than uniformly across the entire support structure. This localized application ensures effective insulation at critical interfaces while minimizing total material quantity required

Inventive Principle:
Principle #3Local quality
