Solution Overview
Problem
Existing door frame structures face challenges in convenient mounting and assembly accuracy due to irreversible welding methods and increased risk of damage during transportation, particularly with large dimensions and heavy materials like aluminum frames.
Innovation Solution
A split connection frame design featuring a first connection frame with a slide rail groove and a second connection frame with a slide plate, allowing for sliding engagement and threaded connections to facilitate easy assembly and alignment, while hiding bolts for aesthetic purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding method is used to assemble door frame, then connection strength is improved, but assembly flexibility and adjustability deteriorate
Solution Approach 1:
The door frame is divided into multiple segments (first door frame segment, second door frame segment, third door frame segment) that can be independently assembled and connected through the connection frame structure, replacing the traditional welded monolithic structure. This segmentation enables disassembly and reassembly while maintaining connection strength.
Solution Approach 2:
The connection frame introduces a dynamic connection mechanism with slide rails, slide plates, and threaded holes that allows for adjustment and repositioning during assembly. The connection can be tightened or adjusted before final fixation, providing adaptability that welding cannot offer.
2Ease of manufacture
If traditional welding method is used, then manufacturing simplicity is improved, but assembly precision and adjustability deteriorate
Solution Approach 1:
The connection frame includes pre-formed slide rails, slide plates, and threaded holes that are manufactured in advance with precise dimensions. These preliminary components guide the assembly process and ensure precise alignment before final tightening, improving assembly precision without complicating manufacturing.
Solution Approach 2:
The connection frame acts as an intermediary component between door frame segments, providing a standardized interface with slide rails and threaded connections. This mediator enables precise and repeatable assembly while maintaining manufacturing simplicity through standardized components.
3Strength
If door frame is assembled as integral structure, then structural strength is improved, but transportation convenience and packaging efficiency deteriorate
Solution Approach 1:
The door frame is segmented into multiple independent parts (first, second, and third door frame segments) connected by connection frames. These segments can be packaged separately in a dispersed state, reducing packaging volume and improving transportation convenience while maintaining structural strength when assembled.
Solution Approach 2:
The connection frame uses detachable connections that allow the door frame to be disassembled into segments for efficient packaging and transportation. Upon installation, the segments are reassembled into the complete door frame structure, recovering the full structural strength.
4Quantity of substance
If dispersed components are used for assembly, then packaging efficiency is improved, but assembly time and complexity increase
Solution Approach 1:
The connection frame components (slide rails, slide plates, threaded holes) are pre-manufactured with precise features that guide the assembly process. This preliminary preparation of connection interfaces enables quick and easy assembly of dispersed segments, reducing assembly time despite the increased number of components.
Solution Approach 2:
The standardized connection frame serves as an intermediary that simplifies the assembly of dispersed door frame segments. The uniform interface design with slide rails and threaded connections reduces assembly complexity and time, making the dispersed component approach efficient.
