Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing guardrail systems require separate fixing bases for different mounting styles, lacking versatility and flexibility in installation direction.

Innovation Solution

A monobloc base with a flat sole, housing, and parallel extensions featuring through holes and grooves allows for versatile mounting of guardrail uprights in French, English, or offset English styles, secured by a bolt through the through holes and with collars fitting into grooves for reinforcement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate fixing bases are used for different mounting styles (French, English, offset English), then each mounting style can be properly supported, but the device complexity and number of components increases

Engineering Contradiction:

Improvemounting style compatibilityVSAvoidnumber of base components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base is designed with a universal structure that can accommodate multiple mounting styles (French, English, and offset English) through a single component. The base includes a flat sole for surface mounting, extensions with through holes for offset mounting, and a housing with grooves for receiving collars in various configurations, allowing one base to perform multiple mounting functions that previously required separate specialized bases

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The base is segmented into distinct functional zones: a flat sole for surface contact, extensions with through holes for bolt fixation, and a housing with grooves for collar reception. This segmentation allows each zone to serve specific mounting requirements while being integrated into a single base component, enabling versatile mounting styles without requiring multiple separate bases

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple specialized bases are used for different mounting configurations, then each configuration is optimized, but the ease of manufacture decreases due to requiring multiple unique parts

Engineering Contradiction:

Improvemounting configuration optionsVSAvoidmanufacturing multiple base types

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If a single base design is used for all mounting styles, then manufacturing is simplified, but the adaptability to different mounting configurations is reduced

Engineering Contradiction:

Improvebase production simplicityVSAvoidmounting style flexibility

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Inventive Principle:

Principle #1Segmentation

4Reliability

If conventional bases without grooves are used, then the structure is simpler, but the stability and reinforcement of the guardrail post fixing is reduced

Engineering Contradiction:

Improvepost fixing stabilityVSAvoidbase structural features

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

AI summary

The single-piece base, for a guardrail upright having at least one collar, comprises: - a flat sole comprising at least one hole for fixing to a surface against or on which the guardrail upright is fixed and - a housing for the upright, between two extensions parallel and perpendicular to the flat sole, opening onto an opening at one end of the extensions opposite the flat sole, each extension having a through hole, the axes of the through holes being coincident. The flat sole has an axis called the "longitudinal axis" and an axis called the "generatrix" parallel to the housing and perpendicular to the longitudinal axis. The housing comprises at least one groove parallel to the axis of the generatrices formed in at least one extension, each groove being configured to receive a collar of the guardrail upright.
