Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple types of gear motors are designed to accommodate different detector combinations, then detector configuration flexibility is improved, but manufacturing costs increase

Engineering Contradiction:
Improvedetector configuration flexibilityVSAvoidmanufacturing costs
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The housing is designed with multiple detector disposition sections that can accommodate different types of detectors (rotation detectors and torque detectors) in various combinations. This universal design allows a single gear motor type to serve multiple detector configuration needs, eliminating the requirement for multiple specialized gear motor types and thereby reducing manufacturing costs while maintaining detector configuration flexibility

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

Solution Approach 2:

The housing is divided into multiple distinct detector disposition sections, each capable of independently accommodating different detector types. This segmentation allows for modular assembly where detectors can be selectively installed in different sections based on specific application requirements, enabling cost-effective production through standardized components with flexible assembly

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If customizations are made for different detector combinations, then detector compatibility is improved, but device complexity increases

Engineering Contradiction:
Improvedetector compatibilityVSAvoidgear motor types
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single gear motor design incorporates multiple detector disposition sections that can accommodate various detector types (rotation detectors at different positions and torque detectors), making one gear motor type compatible with multiple detector combinations. This eliminates the need for multiple specialized gear motor types, thereby reducing device complexity while maintaining detector compatibility

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

Solution Approach 2:

The detector disposition sections are designed to allow flexible assembly and configuration of different detectors based on application needs. This dynamic configurability enables a single standardized gear motor type to adapt to different detector requirements without requiring multiple fixed-design gear motor types, reducing overall system complexity

Inventive Principle:
Principle #15Dynamics
