Universal Counter-Frame for Retractable Sliding Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing counter-frames for retractable sliding doors are not versatile enough to adapt to different sizes, are bulky, and have stability issues during installation, making them unsuitable for DIY applications and inefficient in terms of assembly and transport.
Innovation Solution
A universal counter-frame that can be modified during installation with adjustable components, including a crosspiece, track, and stanchions that can be cut to length, and an adjustable door guiding system suitable for various panel thicknesses, designed to be modular, lightweight, and easy to assemble, with pre-cuts and notches for easy customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional counter-frames are offered as pre-assembled cases with disassembled components, then the structure provides stability and strength, but the volume and bulkiness increase, making transport and storage inefficient
Solution Approach 1:
The counter-frame is divided into modular components (case, stanchions, crosspieces, track) that can be assembled in different configurations. This segmentation allows the structure to maintain strength through proper component connection while reducing transport volume by allowing disassembled storage of individual parts.
Solution Approach 2:
The counter-frame system incorporates adjustable and reconfigurable elements that allow the structure to adapt between compact storage state and expanded installed state. The modular design enables dynamic transformation from a compact disassembled form to a stable assembled structure.
2Ease of manufacture
If counter-frames are designed with fixed standard sizes, then manufacturing and inventory management are simplified, but the adaptability to different opening sizes and door panel thicknesses is reduced
Solution Approach 1:
The counter-frame components are designed with universal connection features and standardized interfaces that allow the same basic parts to be used across different configurations. The case, stanchions, and crosspieces can be assembled in various arrangements to accommodate different opening sizes and door panel thicknesses while maintaining manufacturing efficiency.
Solution Approach 2:
The system incorporates adjustable elements including variable-height stanchions and reconfigurable crosspiece connections that allow the counter-frame to adapt to different dimensional requirements. This dynamic adjustability enables a single set of standardized components to serve multiple installation scenarios.
3Stability of the object's composition
If counter-frames are designed as complete assembled units, then installation stability is ensured, but the complexity of assembly and difficulty of customization for DIY users increases
Solution Approach 1:
The counter-frame is provided as a kit of segmented components with clearly defined assembly sequences. Each component (case, stanchions, crosspieces, track) is designed to be assembled in a logical progression that maintains stability at each stage while keeping the overall assembly process manageable for DIY users.
Solution Approach 2:
The case is pre-assembled as a stable base structure before the stanchions and other components are attached. This preliminary assembly of the core structural element provides a stable foundation that simplifies subsequent assembly steps and ensures overall installation stability while reducing the complexity of the complete assembly process.
