System for retaining an image within a frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods using glass for framing printed images are hazardous, aesthetically limiting, and difficult to secure due to seasonal material fluctuations, and they expose the frame's interior, restricting attractive assembly options.
Innovation Solution
A frame system with an external alignment fixture, snap fittings, and a layered mounting system that allows for hidden fasteners and secure assembly without visible nails, using preassembled frames with injection-molded snap fittings and modular components for easy alignment and secure positioning of printed images between transparent sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If glass sheets are used to frame printed images, then the image appears to float ahead against ambient background with pleasing appearance, but the glass sheets are dangerous to handle and subject to impact or breakage
Solution Approach 1:
The patent replaces fragile glass sheets with acrylic sheets that are safer to handle and less prone to breakage. While acrylic may have different aesthetic properties, it eliminates the safety hazards associated with glass while maintaining the transparent surround effect that allows the frame interior to be visible.
Solution Approach 2:
The patent uses composite construction with acrylic sheets combined with aluminum extrusions and corner blocks to create a frame system that achieves both safety and aesthetic goals. The acrylic provides safety while the aluminum and corner block assembly provides structural integrity and visual appeal.
2Ease of manufacture
If glass sheets are used with transparent surround, then the image floats against background, but the inside of the frame becomes visible which places constraints on attractive assembly and finishing
Solution Approach 1:
The patent divides the frame into separate functional components: aluminum extrusions for structure, corner blocks for joining, acrylic sheets for transparency, and backing materials for finishing. This segmentation allows each component to be optimized independently, enabling both the transparent surround effect and attractive assembly options through selective use of finished vs. unfinished components.
Solution Approach 2:
The patent introduces corner blocks as intermediary components that connect aluminum extrusions and provide mounting surfaces for acrylic sheets and backing materials. These corner blocks act as mediators that enable the transparent display effect while simultaneously providing concealed attachment points for aesthetic finishing materials.
3Productivity
If paired glass sheets are secured using conventional methods, then the frame can be assembled, but it is difficult to secure the paired sheets reliably due to seasonal fluctuations in dimensional materials such as wood moldings
Solution Approach 1:
The patent uses aluminum extrusions with standardized T-slot profiles that provide multiple functions: structural support, alignment guidance, and secure attachment for both acrylic sheets and backing materials. This universal profiling system maintains consistent dimensions across seasonal fluctuations, ensuring reliable securing of components regardless of environmental conditions.
Solution Approach 2:
The patent transitions from dimensional materials like wood that fluctuate with seasonal humidity changes to aluminum extrusions with stable, consistent dimensions. This parameter change in material properties eliminates the reliability issues associated with seasonal expansion and contraction, ensuring secure and reliable assembly throughout the year.

AI summary
A spline installation device for use with a spline/rail type frame to assemble the splines to the rails. The device including a base that defines a platform for receiving a frame subassembly; and a plurality of linkages that are disposed about the platform and coupled to the base. Each linkage is configured to move between a first position in which a fence bearing surface thereof is at an angle other than 90 degrees relative to the platform and a second position in which the fence bearing surface is set at an at least substantially 90 degree angle relative to the platform for locking and holding the frame subassembly in place. The linkages further being configured to receive a spline instillation tool for locking the splines in place relative to the rails.
