Solution Overview

Problem

Existing awning deployment systems face challenges in integrating electrical connections, particularly at the central articulated joint, which are both functionally unsatisfactory and aesthetically unpleasing.

Innovation Solution

A deployment device for awnings that incorporates a flexible sheath with integrated conduits for both a tension link and electrical connections, allowing the arm to pivot smoothly while maintaining a neat appearance and functional integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electrical cable is integrated into the arm of the deployment device, then the electrical connection is provided for LEDs, but the integration is unsatisfactory from functional and aesthetic points of view at the central articulated joint

Engineering Contradiction:
Improveelectrical connection integrationVSAvoidfunctional and aesthetic satisfaction
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The electrical cable is nested within a flexible conduit that is itself contained within the sheath covering the arm. This multi-layer nesting approach allows the cable to be routed through the articulated joint without exposing it, maintaining both functional integrity and aesthetic appearance while accommodating the pivoting motion of the arm.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

A flexible conduit acts as an intermediary between the electrical cable and the external environment. This conduit is housed within the sheath and allows the cable to pass through the articulated joint smoothly, protecting the cable from mechanical stress while maintaining a neat appearance at the joint.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Shape

If a sheath is used to cover the arm, then the appearance is improved, but the sheath must deform during arm pivoting which complicates its design

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidsheath design complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The sheath is made from a flexible material that can deform to accommodate the pivoting motion of the arm while maintaining its protective and aesthetic functions. This flexibility allows the sheath to follow the arm's movement without cracking or detaching, and the material properties enable it to return to its original shape after deformation.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sheath contains nested within it both the electrical cable (through a conduit) and the tension link (through another conduit). This nested arrangement allows all components to move together harmoniously during arm pivoting, reducing the complexity of designing individual routing paths for each component.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If the tension link passes through the articulated joint, then the arm can unfold smoothly, but the cable routing becomes complex and aesthetically unpleasing

Engineering Contradiction:
Improvearm pivoting smoothnessVSAvoidcable routing appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The tension link is routed through a dedicated conduit that is nested within the sheath, similar to how the electrical cable is routed. This nested configuration allows the tension link to pass through the articulated joint smoothly while keeping it hidden within the sheath, maintaining aesthetic appearance while ensuring smooth arm operation.

Inventive Principle:
Principle #7Nested doll (Nesting)
