Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional mounting methods are used for portable RCL systems, then the mounting is secure and reliable, but the installation process is cumbersome and requires tools

Engineering Contradiction:
Improveease of installationVSAvoidinstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The mounting system is divided into separate components: a mounting bracket that attaches to the handrail and a cradle that holds the RCL system. This segmentation allows the bracket to be pre-installed on the handrail using traditional secure methods, while the cradle can be quickly attached and detached without tools, resolving the contradiction between secure mounting and easy installation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cradle incorporates movable and adjustable elements that allow it to adapt to different handrail configurations. The dynamic design enables quick attachment and detachment through simple mechanical actions rather than fixed, tool-required mounting, reducing installation time while maintaining reliability during operation.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If traditional mounting methods are used for portable RCL systems, then the mounting is stable, but the method does not accommodate various handrail configurations

Engineering Contradiction:
Improveadaptability to handrail configurationsVSAvoidmounting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting bracket is designed with universal attachment capabilities that can accommodate various handrail configurations. It features adjustable components and multiple mounting positions that allow the same bracket design to work with different handrail types, sizes, and arrangements, providing adaptability without requiring multiple specialized mounting solutions.

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

Solution Approach 2:

The mounting system incorporates adjustable and reconfigurable elements that allow it to adapt to different handrail configurations. The cradle can be positioned at various locations along the bracket and adjusted to fit different RCL system sizes, providing versatility while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If adjustable hooks are used to accommodate various handrail configurations, then the adaptability is improved, but the mounting stability may be compromised

Engineering Contradiction:
Improveadaptability to handrail configurationsVSAvoidmounting stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The mounting system separates the adaptation function (adjustable hooks and bracket positioning) from the securement function (locking mechanisms and rigid cradle structure). The adjustable elements allow adaptation to various handrail configurations, while the securement features ensure mounting stability during operation, resolving the contradiction between adaptability and reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses adjustable hooks that can be positioned and locked at optimal locations for different handrail configurations. Once positioned, the hooks engage with locking mechanisms that provide stable, reliable mounting during operation. The dynamic adjustment capability during installation transitions to a stable, fixed configuration during use, resolving the apparent contradiction.

Inventive Principle:
Principle #15Dynamics
