Solution Overview

Problem

Existing solutions for drive mechanisms of swing shutters in buildings require complex movement transmission members and wired electrical connections, which are aesthetically and practically inconvenient, especially when integrating with masonry, and often necessitate intervention on the masonry or modification of existing installations.

Innovation Solution

A trunk box design that extends partially below or above the shutter, with a visible solar collector-mounted side for energy supply to an enclosed drive motor, reducing the offset of the drive mechanism relative to the shutter axis and eliminating the need for wired connections by harnessing solar energy, thus avoiding masonry intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wired connection is used to supply electrical energy to the drive motor, then the motor can be powered reliably, but it requires intervention on the masonry or modification of existing installations which is aesthetically and practically inconvenient

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts the electrical power supply from the building's wired electrical installation and provides it through an autonomous source (solar panel) mounted on the trunk box itself, eliminating the need for wired connections through the masonry or window frame

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The trunk box becomes self-sufficient by mounting a solar panel on its visible side to generate electrical energy autonomously, powering the drive motor without requiring external wired connections or intervention on the masonry

Inventive Principle:
Principle #25Self-service

2Ease of operation

If the trunk box is placed outside the construction between the window and closed shutter, then it provides easy access for shutter operation, but it creates aesthetic disadvantages due to visible wiring and offsets the drive mechanism from the shutter axis

Engineering Contradiction:
Improveshutter operation accessibilityVSAvoiddrive mechanism offset
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extends the trunk box in the vertical dimension to span from below the threshold to above the lintel of the opening, allowing the drive mechanism to be positioned closer to the shutter axis while maintaining external accessibility for operation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If complex movement transmission members such as cams, connecting rods, and levers are used to connect the drive mechanism to the shutter, then the shutter can be driven effectively, but the structure becomes complex and aesthetically inconvenient

Engineering Contradiction:
Improveshutter drive effectivenessVSAvoidtransmission mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates complex movement transmission members (cams, connecting rods, levers) by directly connecting the drive mechanism to the shutter, simplifying the overall structure while maintaining effective shutter drive capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using complex transmission members to transfer motion from a remote drive mechanism to the shutter, the patent inverts the approach by positioning the drive mechanism adjacent to the shutter axis, enabling direct connection and eliminating the need for intermediate transmission components

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

The case (16) has a part (19) intercalated between one of the shutters (5, 5`) and a masonry in closing position of the shutters. The part (19) presents a part (22) which is apparent to the outer side of a construction (3) in closed and opened positions of the shutters, where the construction receives the shutters. A solar collector (21) is mounted on the part (22) for supplying power to drive a motor enclosed in the case.
