Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional stacked circuit boards with predetermined layouts are used, then structural stability is maintained, but adaptability to different customer requirements deteriorates

Engineering Contradiction:
Improveadaptability to customer requirementsVSAvoidcircuit board layout complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The circuit board system is divided into multiple independent modules, each providing a specific function (image recording, image processing, signal transmission, power supply, etc.). These modules can be selectively assembled to create different camera variants, enabling adaptability without requiring complete redesign of the entire circuit board layout.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A standardized connection unit design is implemented across all circuit board modules, allowing the same base structure to support multiple functions through different module combinations. This universal interface enables a single circuit board platform to serve multiple customer requirements.

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

2Adaptability or versatility

If the entire circuit board layout is changed to exchange or add functions, then functional adaptability is improved, but manufacturing cost and development effort increase

Engineering Contradiction:
Improvefunctional adaptabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the circuit board into standardized modules with fixed layouts, the need to redesign entire boards is eliminated. Only the specific functional modules need to be changed or added, significantly reducing manufacturing complexity and cost while maintaining functional adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The circuit board modules are pre-designed and pre-assembled with standardized connection interfaces. This preliminary preparation allows for quick configuration of different camera variants by simply selecting and assembling the required modules, avoiding costly last-minute redesigns and rework.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If modular printed circuit boards with connection units are used, then adaptability and ease of customization are improved, but device complexity increases

Engineering Contradiction:
Improvecustomization flexibilityVSAvoidmodular assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The standardized connection unit serves as a universal interface for all modular circuit boards, providing geometric and electrical compatibility across different modules. This universality simplifies the assembly process and reduces the complexity of managing multiple connection types, despite the modular architecture.

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

Solution Approach 2:

All circuit board modules use identical connection unit designs with standardized geometric and electrical characteristics. This homogeneity in the interface design ensures that modules can be freely combined without increasing assembly complexity, as the same connection protocol and physical interface are used throughout the system.

Inventive Principle:
Principle #33Homogeneity
