Solution Overview

Problem

Existing modular screen structures for outdoor spaces face issues such as excessive heating due to the greenhouse effect, poor air circulation, and aesthetically unpleasing visual obstacles from transverse elements, as well as manual and non-regulated height adjustment, which limits versatility and adaptability.

Innovation Solution

A modular screen structure with a base element and an upper element, both supported by vertical uprights with hollow profiles, featuring electromechanical actuation units consisting of electric motors, worm screws, and nuts for controlled sliding, allowing remote height adjustment and minimizing visual obstruction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a single transparent panel is used to protect from the external environment, then shelter is provided during colder months, but excessive heating occurs during dry season due to greenhouse effect and poor air circulation

Engineering Contradiction:
Improvetemperature controlVSAvoidadaptability to seasonal changes
Core Design Contradiction:
TemperatureVSAdaptability or versatility

Solution Approach 1:

The screen structure employs dynamic adjustability through electromechanical actuation units that enable the upper panel to be raised or lowered electrically. This transforms the static single-panel structure into a dynamic system that can adapt its configuration seasonally - providing full coverage during cold months for shelter and raising the panel during dry season to reduce greenhouse effect and improve air circulation, thereby resolving the temperature control versus adaptability contradiction

Inventive Principle:
Principle #15Dynamics

2Temperature

If the entire demarcation system is removed and reinstalled seasonally, then heating issues are avoided, but the operation becomes long, complex and costly

Engineering Contradiction:
Improvetemperature controlVSAvoidtime for removal and reinstallation
Core Design Contradiction:
TemperatureVSLoss of time

Solution Approach 1:

Rather than complete removal and reinstallation, the invention enables partial adjustment by electrically raising or lowering the upper panel while maintaining the base element in position. The electromechanical actuation units allow the upper panel to be repositioned seasonally without dismantling the entire structure, dramatically reducing the time and complexity of seasonal adaptation while maintaining temperature control benefits

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If transverse elements are added to support the panel, then structural stability is improved, but visual obstacles are created in both lowered and raised positions

Engineering Contradiction:
Improvestructural stabilityVSAvoidaesthetic quality
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The invention extracts the transverse support elements from the visible structure by implementing a telescopic configuration where the upper element's uprights slide within the base element's uprights. This removes the need for visible crosspieces in both lowered and raised positions, eliminating visual obstacles while maintaining structural stability through the telescopic guidance mechanism

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The upper element is nested within the base element through telescopic uprights that slide vertically within each other. This nesting configuration eliminates the need for separate transverse support structures, as the nested telescopic mechanism itself provides the necessary structural stability while maintaining aesthetic quality by removing visual obstacles

Inventive Principle:
Principle #7Nested doll (Nesting)

4Device complexity

If manual lifting is required to raise the terminal element, then mechanical simplicity is maintained, but considerable energy output is required especially when panel height exceeds operator height

Engineering Contradiction:
Improvemechanical simplicityVSAvoidease of panel adjustment
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The invention replaces the manual mechanical lifting system with an electromechanical actuation unit consisting of an electric motor, worm screw, and nut mechanism. This substitution eliminates the need for manual force application, allowing electrically-powered raising and lowering of the upper panel with minimal operator intervention, thereby dramatically improving ease of operation while maintaining controlled mechanical action through the worm screw mechanism

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

5Ease of operation

If gas springs are used for lifting, then automatic support is provided, but regulation of lifting height is not possible and intermediate positions cannot be maintained

Engineering Contradiction:
Improveautomatic supportVSAvoidheight regulation capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The worm screw mechanism provides inherent feedback control through its self-locking characteristic, allowing the electric motor to precisely position and hold the upper panel at any intermediate height. The motor can be controlled to stop at desired positions, and the worm screw's friction characteristics prevent unintended movement, enabling height regulation and stable intermediate positions that gas springs cannot achieve

Inventive Principle:
Principle #23Feedback

6Ease of manufacture

If the upper element is completely contained in the base element, then aesthetic quality is improved, but the structure lacks versatility for different environmental situations

Engineering Contradiction:
Improveaesthetic qualityVSAvoidadaptability to environmental conditions
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The invention implements dynamic versatility through electromechanical actuation that allows the upper element to be positioned anywhere within the range defined by the telescopic uprights. The system can be completely contained for aesthetic quality or extended to various intermediate positions for adaptability to different environmental conditions, providing both aesthetic quality and versatility through controlled dynamic positioning

Inventive Principle:
Principle #15Dynamics
