Solution Overview

Problem

Existing sun and/or rain protection systems require significant space due to the need for fully extended guide carriages to maintain a defined distance between protective elements, limiting partial extension and affecting functionality and aesthetics.

Innovation Solution

Incorporation of positioning elements and corresponding position indicators on guide carriages that allow for defined positioning along a rail, eliminating the need for connecting elements and enabling partial extension, with optional locking mechanisms for secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If connecting elements are used to maintain defined distance between guide carriages, then the distance between protective elements is maintained, but the guide device requires considerable space and cannot be partially extended

Engineering Contradiction:
Improvedefined distance between protective elementsVSAvoidspace required by guide device
Core Design Contradiction:
Manufacturing precisionVSArea of stationary object

Solution Approach 1:

The patent removes the connecting elements (scissor-joint-like elements, coupling arms, toothed belts) that previously connected guide carriages together. Instead, each guide carriage is independently positioned along the rail using positioning elements (locking pins, cam mechanisms) that engage with position indicators (recesses, notches) on the rail, eliminating the need for inter-carriage connecting elements and reducing the space required.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system divides the guide carriages into independent units that can be individually positioned and locked at specific locations along the rail. Each guide carriage has its own positioning element that can engage with position indicators independently, allowing partial extension and independent control of each carriage without requiring the entire system to be fully extended.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If guide carriages are fully extended to achieve defined distance, then the protective elements are properly positioned, but partial extension is not possible and functionality is impaired

Engineering Contradiction:
Improvedefined distance between guide carriagesVSAvoidpartial extension capability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system transitions from a static, fully extended configuration to a dynamic system where guide carriages can be independently positioned at various locations along the rail. The positioning elements allow each carriage to be locked at specific positions, enabling flexible partial extension configurations adapted to different functional requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent enables partial extension by allowing only the necessary number of guide carriages to be extended to the required positions, rather than requiring all carriages to be fully extended. This partial action achieves the defined distance requirement for the active protective elements while leaving other carriages in a retracted or intermediate state.

Inventive Principle:
Principle #16Partial or excessive action

3Stability of the object's composition

If connecting elements are used to link guide carriages, then the system maintains structural integrity, but the guide carriages and connecting elements occupy excessive space

Engineering Contradiction:
Improvestructural integrity of guide deviceVSAvoidspace occupied by guide carriages and connecting elements
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The patent removes the bulky connecting elements (scissor joints, coupling arms) that previously provided structural linkage between guide carriages. Structural integrity is maintained through the rail system itself and individual positioning elements on each carriage that engage with the rail, eliminating the need for inter-carriage mechanical linkages and significantly reducing the volume occupied by the guide device.

Inventive Principle:
Principle #2Taking out (Extraction)
