Curved Frame Profile Cover for Seamless Canvas Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fixing joints for canvases on frame structures do not allow complete coverage, resulting in uncovered spaces at the junctions between frames, which degrade visual rendering and waste space, especially when multiple frames are assembled.
Innovation Solution
A fixing device with a curved covering part that extends beyond the profile's outer edge, allowing the canvas to occupy the entire frame surface, and featuring a removable fixing mechanism for easy assembly and adjustment, ensuring continuous coverage without gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing joints are used to attach canvas to frame structure, then the canvas can be fixed to the frame, but uncovered spaces appear at the junctions between frames, degrading visual rendering
Solution Approach 1:
The fixing device incorporates a curved covering portion that arches over the frame profile, extending beyond the straight edges to reach adjacent frames. This curvature allows the canvas to wrap around and cover the junction areas between frames, eliminating visual gaps and improving overall rendering quality.
Solution Approach 2:
The covering portion extends in a third dimension beyond the flat plane of the frame, projecting outward to cover the vertical edges and junction areas. This dimensional extension allows the canvas to cover areas that would otherwise remain exposed at frame intersections.
2Productivity
If conventional fixing joints are used, then the canvas can be attached to the frame, but the usable space of the frame is reduced due to uncovered edges
Solution Approach 1:
The curved covering portion maximizes the use of available frame width by arching outward to cover the entire frame profile, including the outer edges. This design allows the canvas to occupy the full width of the frame structure, increasing the effective usable space.
3Reliability
If the covering portion extends beyond the profile outer edge to eliminate gaps, then visual rendering improves, but the fixing device becomes more complex
Solution Approach 1:
The fixing device merges multiple functions into a single integrated component: the fixing portion attaches the device to the frame groove, while the covering portion simultaneously covers the frame profile and enables canvas attachment. This consolidation simplifies the overall structure despite the extended functionality.
Solution Approach 2:
The covering portion serves multiple purposes: it acts as a structural cover for the frame profile, provides an extended surface for canvas attachment, and creates overlapping coverage at frame junctions. This multi-functionality reduces the need for separate components.
4Area of stationary object
If the covering portion is made wider to cover the entire profile width, then canvas coverage is maximized, but the fixing device becomes less compact
Solution Approach 1:
The curved cross-section of the covering portion allows it to cover the entire width of the frame profile while maintaining a compact form factor. The arching shape efficiently spans the width without requiring excessive material or volume, as the curvature provides structural strength with minimal mass.
