Solution Overview

Problem

Existing rail systems for welding tables lack efficient assembly and increased versatility, with anti-tilt devices often posing tripping hazards due to their design.

Innovation Solution

A rail system incorporating a base rail with a round rail and anti-tilt recess, combined with a roller foot featuring an anti-tilt device that can be attached to the base body in multiple positions, allowing for smooth operation on round rails in both loaded and unloaded states without tripping hazards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate support and foundation rails are used, then assembly complexity increases, but manufacturing precision and reliability are improved

Engineering Contradiction:
Improveassembly reliabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the support rail and foundation rail into a single integrated rail structure. The support rail includes a base portion for floor mounting and an extending portion that provides the foundation function, eliminating the need for separate support and foundation rails while maintaining structural reliability

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If anti-tilt device protrudes far beyond displacement foot, then anti-tilt function is improved, but safety deteriorates due to tripping hazard

Engineering Contradiction:
Improveanti-tilt functionVSAvoidtripping hazard
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The anti-tilt device is nested within the displacement foot structure. The anti-tilt protrusion is positioned inside or integrated with the displacement foot body, allowing it to perform its anti-tilt function while remaining hidden from view and eliminating the tripping hazard of protruding elements

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent introduces a recess in the rail that receives the anti-tilt protrusion, creating an intermediary structure that allows the anti-tilt device to function effectively while keeping the protrusion contained and invisible from a distance, thus eliminating the tripping hazard

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If round rail is separately installed, then versatility is improved, but assembly time increases

Engineering Contradiction:
Improverail system versatilityVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The round rail is integrated into the support rail structure as part of the same manufactured component. The support rail includes both the linear support structure and the circular foundation rail portion, allowing both functions to be provided by a single pre-assembled unit that reduces installation time while maintaining versatility

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The aim of the invention is to advantageously develop a rail (200) of a rail system for welding tables, comprising a base rail which is designed to be secured on or in a floor and has multiple openings corresponding to the openings of the welding tables; a connecting frame (418) of a rail system for welding tables, said connecting frame being provided with rollers which are designed to interact with a circular rail; and a caster (500) of a rail system for welding tables, said caster comprising a main part, rollers, and a tilting protection device. According to the invention, the rail (200) is developed in that a circular rail is secured in a recess of the base rail, the connecting frame (418) is developed in that a recess (407) is provided in each base plate (406) of the connecting frame (400), a rotating assembly roller being securable in said recess in different rotational positions, and the caster (500) is developed in that the rollers are designed to interact with a circular rail and the tilting protection device is designed to interact with a tilting protection recess and a tilting protection edge of a rail (200).
