Solution Overview

Problem

Existing protective covers struggle with achieving a further reducible compression dimension while maintaining mechanical strength and ease of manufacture, particularly due to the design of connectors that require long arms or multiple couplings for maintaining spacing between shielding elements.

Innovation Solution

The connectors are designed with a central web connected to the second leg of a shielding element and at least one arm connected to an adjacent shielding element, allowing direct integration without additional coupling, featuring pivotable arm sections and material bonding for compactness and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If traditional connectors with long arms or multiple couplings are used to maintain spacing between shielding elements, then the spacing requirement is met, but the compression dimension increases and manufacturing complexity increases

Engineering Contradiction:
Improvecompression dimensionVSAvoidconnector structure complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The connector is segmented into a central web and multiple arms that can pivot independently. This segmentation allows the connector to achieve the required spacing function through coordinated movement of multiple simpler components rather than requiring a single complex long-arm structure, thereby reducing the compression dimension while maintaining functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector employs pivotable arms that can dynamically adjust their positions to maintain the required spacing between shielding elements during extension and retraction. This dynamic adaptation eliminates the need for fixed long arms, enabling a more compact compression dimension while preserving the spacing function throughout the range of motion.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If traditional connectors with multiple couplings are used, then spacing between shielding elements is maintained, but the number of parts increases and manufacturing cost increases

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidconnector connection reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

Multiple coupling functions are merged into a single integrated connector structure consisting of a central web and multiple arms. This consolidation reduces the total number of separate parts and couplings required, simplifying manufacturing while maintaining reliable spacing maintenance through the coordinated action of the integrated components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector structure serves multiple functions simultaneously: the central web provides structural support and attachment points, while the pivotable arms maintain spacing between shielding elements. This multi-functionality eliminates the need for separate coupling components, reducing part count and manufacturing complexity while ensuring reliable operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A protective cover (1) comprises a plurality of shielding elements (2, 3), which are in particular L-shaped in cross-section. The shielding elements (2, 3) are movably linked to one another by coupling connectors (5, 5a, 5b). The shielding elements (2, 3) each have a first leg (2.1, 3.1) and at least one second leg (2.2, 3.2) angled relative to its first leg (2.1, 3.1), the second legs (2.2, 3.2) being arranged with their end faces opposite each other such that the first legs (2.1, 3.1) of the immediately adjacent shielding elements (2, 3) overlap at least partially, forming a shielding surface (4) with variable length. At least one, preferably each, of the connectors (5, 5a, 5b) has a central web (5.1) which has at least two arms (5.2, 5.3) pivotably arranged on it. The central web (5.1) of a connector (5, 5a, 5b) is connected to the second leg (2.2, 3.2) of a shielding element (2, 3) and at least one arm (5.2, 5.3) of this connector (5, 5a, 5b) is connected to the second leg (2.2, 3.2) of an immediately adjacent shielding element (2, 3).
