Interlocking Picture Mounting Frame for Precise Adhesive Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing picture mounting methods require precise alignment and often result in damage to the picture or mounting due to the difficulty in re-alignment, especially when using self-adhesive materials.
Innovation Solution
A self-tensioning picture mounting system with a central display panel and interlocking spars, utilizing fold lines and detent mechanisms for easy alignment and adhesion, providing structural integrity and tension to the flexible picture web, and alternative attachment methods like staples for precise alignment and invisible attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If self-adhesive materials are used for mounting pictures, then the mounting process becomes simpler and more inexpensive, but precise alignment becomes difficult and re-alignment results in damage to the picture or mounting
Solution Approach 1:
The patent applies preliminary action by providing alignment marks and guide features on the mounting panel before the adhesive is applied. These pre-established guides enable precise positioning of the picture during the mounting process, eliminating the alignment difficulties associated with direct self-adhesive application. The alignment marks serve as preliminary structural elements that facilitate accurate placement before final adhesion occurs.
2Reliability
If adhesive is applied to the entire front face of the display panel, then the picture adheres securely, but alignment becomes critical and difficult to adjust
Solution Approach 1:
The patent applies local quality by concentrating the adhesive application to specific localized areas rather than the entire front face of the display panel. Adhesive strips or dots are positioned at strategic locations where they provide sufficient holding force while allowing the picture to be aligned using the guide features. This localized adhesive application maintains secure adhesion while significantly improving alignment ease and adjustability during the mounting process.
3Device complexity
If a flexible picture web is mounted without a rigid structure, then the mounting is simpler and less expensive, but the picture lacks structural rigidity for proper display
Solution Approach 1:
The patent applies segmentation by dividing the mounting structure into distinct functional components: a rigid mounting panel with integrated guide features and alignment marks, and the flexible picture web. The rigid panel provides the necessary structural support and stability, while the segmented design allows the flexible picture to be independently positioned and aligned using the guide features before being secured to the rigid structure.

AI summary
A picture mounting has: a web having a display panel which has a display surface on its front face, the display panel having a perimeter defined by a frame having a plurality of spars; each spar being made of leaves created from the web and extending from the perimeter of the display panel, each of the leaves being folded at least twice, in a rearward direction to create a spar having a polygonal cross-section; each spar having an adhesive region located on a surface of one of the leaves and by means of which a picture is adhered to the respective spar; the spars being mutually interlocking thereby to retain the spars adjacent the rear surface of the display surface and thereby to create the frame.
