Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a glue or snap structure is used to seal the opening, then the device achieves water resistance, but the manufacturing and disassembly become difficult

Engineering Contradiction:

Improvewater resistanceVSAvoiddifficulty in manufacture

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The sealing structure is divided into separate components: a sealing ring and a sealing block. The sealing ring is installed on the antenna, and the sealing block is integrated into the housing with a receiving hole. This segmentation allows each component to be manufactured independently and assembled together, simplifying the manufacturing process while maintaining effective sealing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sealing block acts as an intermediary component between the housing and the sealing ring. It provides a structured interface with engagement structures that facilitate easy assembly and disassembly while ensuring reliable water resistance. The intermediary sealing block translates the sealing function into a modular, user-friendly system.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If a sealing structure is added to ensure waterproofing, then the device achieves better water resistance, but the device complexity increases

Engineering Contradiction:

Improvewater resistanceVSAvoidsealing structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The sealing block integrates multiple functions into a single component: it provides the receiving hole for the antenna, incorporates engagement structures for easy assembly, and works with the sealing ring to ensure water resistance. By merging these functions into one component, the overall device complexity is reduced despite achieving reliable waterproofing.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sealing block serves multiple purposes: it structures the opening, facilitates assembly through engagement structures, and enables waterproofing when combined with the sealing ring. This multi-functionality reduces the need for additional separate components, thereby simplifying the overall device design while maintaining effective sealing.

Inventive Principle:

Principle #6Universality (Multi-functionality)
