Solution Overview

Problem

Guardrails on elevated construction surfaces often fail to prevent falls due to inadequate securing, leading to potential accidents.

Innovation Solution

A guardrail mounting bracket system comprising an upper bracket assembly, a lower bracket, and a clamp fastener that biases the upper clamp component towards the lower bracket, securely attaching the guardrail to the elevated slab surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If guardrails are placed at the perimeter of elevated surfaces, then fall prevention coverage is improved, but the guardrails can move and fail to prevent falls if not properly secured

Engineering Contradiction:
Improveguardrail securityVSAvoidmounting system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting system is divided into separate components: an upper bracket assembly with clamp components, a lower bracket, and fasteners. This segmentation allows each component to perform a specific function (clamping, supporting, securing) while collectively providing a reliable guardrail attachment system that prevents movement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The upper bracket assembly combines multiple elements (upper support component, upper clamp component, lower clamp component, fasteners) into an integrated unit that simultaneously provides clamping force, structural support, and secure attachment to the guardrail post, resolving the contradiction by merging functions into a unified mounting system.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a clamp fastener system is used to secure the guardrail, then guardrail stability is improved, but the mounting process requires more steps and time

Engineering Contradiction:
Improveguardrail stabilityVSAvoidmounting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The upper bracket assembly is pre-configured with clamp components and fastener engagement features before installation. The clamp components are pre-positioned to engage with the lower bracket and guardrail post, allowing workers to simply tighten fasteners rather than assemble multiple components during installation, thus maintaining stability while reducing mounting time.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the upper clamp component is selectively biased towards the lower bracket, then guardrail movement prevention is improved, but the clamp fastener mechanism becomes more complex

Engineering Contradiction:
Improvemovement preventionVSAvoidclamp fastener mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The clamp fastener system is designed to be self-biasing, where tightening the fastener automatically creates the selective bias between the upper and lower clamp components. The mechanism uses the fastener's own tightening action to generate the necessary clamping force and positional bias, eliminating the need for additional springs, actuators, or complex biasing mechanisms.

Inventive Principle:
Principle #25Self-service

AI summary

A guardrail mounting bracket includes an upper bracket assembly comprising an upper support component and an upper clamp component; a lower bracket, wherein the upper clamp component is oriented between the upper support component and the lower bracket; and a clamp fastener supported by the upper support component and configured to engage the upper clamp component, the clamp fastener movable relative to the upper support component to selectively bias the upper clamp component towards the lower bracket.
