Rigid Protective Cover With Edge Frame And Spring Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective covers for books and similar items often fail to provide comprehensive protection and easy access, as they either lack full coverage or have cumbersome designs that do not securely keep the edges closed.
Innovation Solution
A protective cover featuring an edge frame with a pull bar, connector arms, and a spine insert, which allows for secure closure and storage, using pivot tabs, slide pegs, and a spring band to ensure the edges are fully covered and protected while allowing easy opening and closure, with optional storage compartments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full coverage sleeve with zip fastener is used to fully envelop a bound book, then comprehensive protection is provided, but the design becomes cumbersome and difficult to operate
Solution Approach 1:
The protective cover is divided into separate functional components: an edge frame that envelops the book edges, a spine insert that secures to the book spine, and connector arms that link them. This segmentation allows each component to perform its specific function efficiently while simplifying the overall closure mechanism compared to a full zip envelope.
Solution Approach 2:
The invention extracts only the essential protective function from a full coverage sleeve, focusing protection on the vulnerable book edges through the edge frame while using the spine insert and connector arms for secure attachment, eliminating the need for a cumbersome full-zip envelope design.
2Ease of operation
If elastic bands are used to keep covers closed, then the design is simple, but the edges of the book are exposed and unprotected
Solution Approach 1:
The invention merges the simple elastic band closure concept with an edge frame structure. The edge frame actively envelops and protects the book edges, while elastic bands or spring bands provide the closing force to secure the frame around the book, combining structural protection with simple elastic closure.
Solution Approach 2:
The connector arms serve multiple functions: they connect the edge frame to the spine insert, provide structural support, and work with spring bands to provide both closure force and protection for the book edges, eliminating the need for separate protective elements.
3Strength
If a rigid structure is used to provide robust protection, then durability is improved, but the device becomes more complex with multiple components
Solution Approach 1:
The spine insert is inserted into the book spine, and the connector arms connect this insert to the edge frame, creating a nested structure where components fit within and support each other. This nesting provides robust protection while keeping the overall structure compact and the number of components manageable.
Solution Approach 2:
The connector arms incorporate pivot tabs and slide pegs that allow dynamic movement and adjustment, enabling the rigid protective structure to adapt to different book sizes and shapes while maintaining strong protection, rather than requiring multiple fixed rigid components.
