Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bolt and nut connections are used to connect treatment bed legs to base support tubular elements, then the connection provides structural stability, but the assembly process becomes complex and time-consuming

Engineering Contradiction:

Improveconnection stabilityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The connecting device is divided into distinct modular components: a central axis component, connecting elements with locking mechanisms, and interface portions. This segmentation allows for pre-assembly and testing of individual parts, enabling rapid deployment of the complete connection system without complex on-site assembly procedures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting device incorporates pre-configured locking mechanisms and pre-assembled connecting elements that are prepared in advance. The central axis component includes pre-positioned locking features and the connecting elements come with pre-installed adjustment mechanisms, eliminating the need for complex assembly operations during actual bed setup.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If multiple components are used in the connection mechanism to ensure stability, then the connection robustness improves, but the device complexity increases

Engineering Contradiction:

Improveconnection robustnessVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The connecting device merges multiple functions into integrated components. The central axis component combines structural support, rotation capability, and locking mechanisms in a single element. The connecting elements integrate attachment features, adjustment capabilities, and securing mechanisms, reducing the total component count while maintaining connection robustness.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connecting device employs universal interface designs that can accommodate different leg configurations and base support types. The central axis and connecting elements are designed with standardized interfaces and adjustable features that work across various treatment bed configurations, reducing the need for multiple specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If traditional bolt and nut connections are used, then the connection provides structural integrity, but tool dependency increases

Engineering Contradiction:

Improveconnection integrityVSAvoidtool requirement

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The connecting device incorporates self-locking mechanisms and self-adjusting features that do not require external tools for operation. The locking mechanisms automatically secure the connection when components are assembled, and adjustment features can be modified by hand, eliminating dependency on specialized assembly tools while maintaining strong structural integrity.

Inventive Principle:

Principle #25Self-service

4Productivity

If hinged mechanisms with locking pins are used for quick assembly, then the assembly speed improves, but the range of movement is restricted

Engineering Contradiction:

Improveassembly speedVSAvoidrange of movement

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The connecting device incorporates dynamic adjustment capabilities that allow the connection to adapt to different positions and angles. The central axis component enables rotational movement, and the connecting elements include adjustable locking mechanisms that can secure the connection at multiple positions, providing both quick assembly and versatile range of motion.

Inventive Principle:

Principle #15Dynamics
