Solution Overview

Problem

Existing clamp assemblies for securing rails or rail ribbons during transport are complex, costly, and require multiple moving parts, posing safety risks and increasing transportation complexity.

Innovation Solution

A clamp assembly with a first and second clamp device on opposite sides of an elongated body, each comprising a housing, pivotally coupled clamps, and an actuator that can pivot the clamps into engagement or disengagement with the body, assisted by biasing members to ensure secure holding even in actuator failure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional clamp assemblies are used to secure rails during transport, then the rails can be held in place, but the clamp complexity and cost increase due to multiple moving parts

Engineering Contradiction:
Improverail securing reliabilityVSAvoidclamp structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the functions of multiple clamps into a single integrated clamp assembly. The assembly includes a housing with multiple clamp members (at least two clamp members) that are pivotally coupled to the housing and work together to secure the rail. This merging of functions reduces the number of separate components needed while maintaining the reliability of rail securing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The clamp assembly is designed as a multi-functional device that can prevent rail sliding in multiple directions simultaneously. The housing with multiple pivotally coupled clamp members can engage with the rail from different positions, providing universal securing capability against various sliding directions without requiring multiple separate clamp devices.

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

2Reliability

If multiple clamps are used to prevent sliding in opposite directions, then sliding prevention is improved, but the quantity of components and cost increase

Engineering Contradiction:
Improvesliding prevention capabilityVSAvoidnumber of clamp components
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

Multiple clamp members are merged into a single integrated assembly with a common housing. The housing supports at least two clamp members that are pivotally coupled to it, allowing them to work together as one unit. This reduces the total number of separate components while maintaining the capability to prevent sliding in opposite directions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The clamp assembly is segmented into modular components including a housing and multiple pivotally coupled clamp members. This segmentation allows the multiple clamp functions to be integrated into one assembly rather than requiring multiple complete clamp units, reducing overall component quantity while maintaining functionality.

Inventive Principle:
Principle #1Segmentation

3Reliability

If complex clamp mechanisms are used to secure rails, then securing reliability is improved, but safety risks increase due to more moving parts

Engineering Contradiction:
Improveclamp engagement reliabilityVSAvoidsafety risks from moving parts
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By merging multiple clamp functions into a single integrated assembly with a common housing, the total number of moving parts is reduced compared to using multiple separate clamp mechanisms. The pivotally coupled clamp members within the single assembly share common mounting points and structural support, reducing the overall quantity of moving components while maintaining engagement reliability.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A clamp assembly (104) includes a housing (318) that can be positionable alongside an elongated body (102), one or more clamps (314) that can be pivotally couplable with the housing (318), and an actuator (332) that may pivot the one or more clamps (314) relative to the housing (318). The clamps (314) may selectively engage the elongated body (102) to thereby restrict movement of the elongated body (102) relative to the housing (318).
