Solution Overview

Problem

Existing banner support assemblies are unable to effectively support rigid banners, especially under wind loads, as they rely on flexible materials that cannot withstand the weight and stress of rigid banners.

Innovation Solution

A rigid banner support assembly comprising an external arm with an open cavity connected to a support member, an internal arm connected to the rigid banner, and at least one biasing member, such as a spring-loaded bolt system, allowing vertical movement of the internal arm relative to the external arm in response to wind forces above a threshold, enabling the banner to bow and reducing damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If flexible banner support assemblies are used, then the structure can accommodate wind loads through flexibility, but rigid banners cannot be supported as they exceed the load-bearing capacity of flexible materials

Engineering Contradiction:

Improveload-bearing capacityVSAvoidcompatibility with rigid banners

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The support assembly incorporates a movable internal arm that can dynamically adjust its position relative to the external arm. The biasing member allows the internal arm to move vertically in response to wind forces, enabling the structure to adapt to varying load conditions while maintaining the ability to support rigid banners.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The biasing member changes the mechanical parameters of the system by providing a controllable degree of freedom. This allows the internal arm to move between fixed and mobile states, adjusting the overall stiffness and flexibility of the support assembly to match different banner types and environmental conditions.

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If the internal arm is fixed relative to the external arm, then structural stability is maintained, but the banner cannot bow under wind forces leading to increased damage risk

Engineering Contradiction:

Improvestructural stabilityVSAvoidwind damage risk

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The internal arm transitions from a fixed position to a movable one controlled by the biasing member. This dynamic capability allows the banner to bow and flex under wind forces, reducing the risk of damage while maintaining structural stability through the controlled movement mechanism.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The biasing member is pre-configured to provide cushioning against excessive movement. It allows controlled bowing of the banner under normal wind conditions while preventing excessive deformation that could lead to damage, effectively cushioning the system against harmful wind forces.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Ease of manufacture

If a rigid fixed structure is used for the support assembly, then manufacturing and installation are simplified, but the banner cannot respond to wind forces causing increased damage

Engineering Contradiction:

Improveassembly simplicityVSAvoidbanner protection under wind load

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The support assembly is divided into distinct segments: an external arm, an internal arm, and a biasing member. This segmentation allows each component to be manufactured and assembled separately, maintaining relative simplicity while enabling the internal arm to move independently in response to wind forces, thereby protecting the banner.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The segmented design incorporates a dynamic element through the biasing member that connects the internal arm to the external arm. This allows the assembly to maintain ease of manufacture through modular construction while providing the reliability needed to protect banners under wind loads through controlled movement.

Inventive Principle:

Principle #15Dynamics
