Window Fitting Element Rebate Base Recess Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door fitting elements require multiple screw attachments for minimal burglary protection, leading to complex assembly and precise fixation challenges due to easy shifting during fastener insertion.
Innovation Solution
A fitting element with a rebate base element that engages in a recess on the frame, preventing displacement and allowing exact positioning, combined with a side that rests on a frame wall to divide the rebate surface into sections, simplifying assembly and enhancing burglary protection by reducing twisting attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fastening screws are used to secure the fitting element to the frame, then burglary protection is improved, but the assembly complexity increases and precise positioning becomes difficult due to shifting during insertion
Solution Approach 1:
The fitting element is pre-positioned on the rebate surface using a foot element that engages with a corresponding recess in the frame. This preliminary positioning action prevents the fitting element from shifting during the subsequent fastening process, allowing for precise and simplified assembly while maintaining multiple fastening points for burglary protection
Solution Approach 2:
A foot element acts as an intermediary component between the fitting element and the frame. This foot element engages with a recess in the frame to provide preliminary positioning, thereby mediating between the fitting element and the multiple fastening screws to prevent shifting and simplify assembly
2Manufacturing precision
If multiple fastening screws are used to prevent shifting, then positioning precision is improved, but the installation time and complexity increase
Solution Approach 1:
The foot element performs a preliminary positioning action by engaging with a recess in the frame, which pre-establishes the correct position of the fitting element before fastening. This eliminates the need for time-consuming adjustments and precise alignment during installation, thereby reducing installation time while maintaining positioning precision
Solution Approach 2:
The positioning function is segmented into two distinct stages: preliminary positioning by the foot element engaging with the recess, and final securing by the fastening screws. This segmentation allows the positioning precision to be achieved through the dedicated foot element mechanism without requiring multiple complex fastening operations, thus reducing installation time
