Building Wall Opening Structure for External Shutter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods face difficulties in installing and assembling shutters and motorized systems in building perimeter walls without internal access, due to the thickness of the walls and safety constraints, making it hard to position scaffolds and wire motorized systems externally.
Innovation Solution
A structure comprising thermally insulating and reinforcement layers, side appendages, and support elements that allow for external assembly and installation of shutters, with brackets for precise positioning, guide grooves for shutter operation, and integrated solar panels and electricity storage for self-sufficiency, enabling external wiring and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional scaffolds are used for installation, then safety is ensured, but the ability to work on external façade without internal access is limited
Solution Approach 1:
The structure is divided into multiple independent panels (first panel, second panel, third panel, fourth panel) that can be assembled separately from outside the building. Each panel can be independently positioned and connected, allowing workers on scaffolds to complete the installation without needing internal access.
Solution Approach 2:
The panels are designed to extend in multiple dimensions - horizontally across the opening and vertically along the wall. This multi-dimensional configuration allows the structure to be assembled externally while maintaining structural integrity and providing the necessary support functions.
2Loss of energy
If wall thickness and structure dimensions are considered, then thermal insulation is improved, but installation difficulty increases
Solution Approach 1:
By segmenting the insulating structure into multiple thin panels rather than one thick monolithic structure, the installation becomes more manageable. Each panel can be handled and positioned independently on scaffolds, while collectively they provide the required thermal insulation equivalent to the wall thickness.
Solution Approach 2:
The structure uses composite construction with panels comprising reinforcement layers and insulating material layers. This composite approach allows the structure to achieve both mechanical strength and thermal insulation properties while maintaining installability through panelization.
3Ease of manufacture
If internal access is required for wiring, then motorized system installation is simplified, but access to internal spaces is needed causing discomfort
Solution Approach 1:
The wiring and electrical components for the motorized shutter systems are extracted from the interior installation process and repositioned to be accessible from the exterior. Electrical conduits and wiring channels are integrated into the external panel structure, allowing all electrical work to be completed from outside the building.
Solution Approach 2:
The external panels serve as intermediary structures that provide both mechanical support and electrical pathways. The panels include integrated channels and conduits that mediate between the external motorized systems and the shutters, enabling wiring to be routed externally without penetrating the building interior.
4Ease of operation
If components are made lightweight for easy transport, then assembly ease is improved, but structural strength may be compromised
Solution Approach 1:
Each panel is constructed as a composite structure with reinforcement layers (providing strength) and insulating material layers (providing thermal performance). This composite construction allows the panels to be lightweight enough for manual handling while maintaining the structural strength required to support the shutters and resist environmental loads.
