Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Guardrails on staircases often fail to provide a stable gripping point and prevent falls due to improper securing, leading to wobbling or detachment from the staircase.

Innovation Solution

A guardrail mounting bracket system comprising upper and lower clamping brackets and a front clamping bracket, secured to the staircase using a connector bolt, which engages the guardrail post and staircase surfaces to ensure stable mounting and prevent movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional guardrail mounting methods are used, then installation is simple, but the guardrail becomes unstable and may wobble or detach

Engineering Contradiction:

Improveguardrail stabilityVSAvoidmounting bracket complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The mounting bracket is divided into multiple clamping brackets (upper clamping bracket, lower clamping bracket, front clamping bracket) that independently engage with different parts of the staircase structure. Each clamping bracket secures a specific portion, and together they provide comprehensive stabilization of the guardrail system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clamping brackets are nested together through connectors to form a hierarchical structure. The front clamping bracket connects to the lower clamping bracket, which connects to the upper clamping bracket, creating a nested arrangement that distributes mounting forces across multiple engagement points with the staircase.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If multiple clamping brackets are used to secure the guardrail, then stability improves, but installation complexity increases

Engineering Contradiction:

Improvemounting stabilityVSAvoidinstallation ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The mounting system incorporates adjustable features that allow the clamping brackets to be positioned and secured at various locations along the staircase. The connectors enable dynamic assembly and disassembly, making installation straightforward despite the multiple components involved.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Connectors serve as intermediary elements that simplify the assembly process by providing standardized connection interfaces between the clamping brackets and the staircase structure. These intermediaries enable easy attachment and detachment without requiring complex fastening procedures.

Inventive Principle:

Principle #24Intermediary (Mediator)
