Self-supporting book with segmented covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional books are difficult to prop up securely on a flat surface due to stiff bindings and lack of structural rigidity, which can cause pages to involuntarily change or close, and existing solutions either weaken the cover or interfere with user clothing.
Innovation Solution
A self-supporting book design featuring a front cover with a flexible joint, a back cover connected to a spine, and a third cover with a stabilizing sheet that provides structural support when propped up, using an elastic member or hook-and-loop fasteners to maintain stability and prevent collapse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a folding member is used to prop the book up, then the book can be supported at various angles, but the cover and binding are weakened and structural rigidity is insufficient
Solution Approach 1:
The book is divided into four separate covers (front cover, back cover, first inner cover, second inner cover) that can be independently positioned. The inner covers can be folded back to create support surfaces while the outer covers remain intact, distributing the structural stress away from the binding and main covers.
Solution Approach 2:
The invention adds a fourth cover that extends beyond the binding in a direction perpendicular to the traditional book structure. This extension provides an additional support surface that creates a stable tripod configuration when propped, distributing weight across multiple points rather than concentrating stress on the binding.
2Ease of operation
If hook & loop fasteners are used to prop the book, then the book can be secured at various angles, but the connection lacks structural rigidity and interferes with user clothing
Solution Approach 1:
The book structure is segmented into multiple independent covers that can be positioned at different angles. The inner covers can be folded back to create support surfaces, providing multiple geometric support points that inherently stabilize the book without requiring additional fastening mechanisms.
Solution Approach 2:
The invention removes the need for external fastening mechanisms like hook & loop fasteners by using the book's own cover structure to create support surfaces. The geometric configuration of the four covers themselves provides the stabilization function, eliminating the need for separate fastening components that would interfere with clothing.
3Strength
If stiff bindings are used in traditional books, then the book maintains structural integrity, but the book is difficult to hold open on a flat surface
Solution Approach 1:
The book is divided into four separate covers that can move independently relative to each other. The inner covers can be folded back while the outer covers remain stationary, allowing the book to open and spread flat on a surface without the stiff binding forcing the entire book structure to move as one unit.
Solution Approach 2:
The book structure transitions from a static, rigid configuration to a dynamic, adaptable configuration. The multiple flexible joints between covers allow the book to assume different shapes - standing upright for portability or spreading flat on a surface for reading - while the binding remains intact and functional.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the book to be securely propped up in a hands-free manner with lay-flat pages, allowing for easy reading and display, while maintaining the structural integrity of the cover and preventing interference with user clothing.

AI summary
A book has a front cover having a first edge which is unconnected, and an opposing second edge which is connected to a spine, A back cover has a first edge which is connected to the spine and an opposing second edge which is connected to flexible joint or fold-line. The book has a third cover having a first edge which is connected to the flexible joint, that couples the third cover to the back cover, and an opposing second edge which is connected to binding. The front cover is configured to fold back about the spine to retain the third cover proximal the second edge of the third cover to retain the book in a propped -up position for reading. A page holder s!ides along the left and right sides of the third cover and has an opening that allows a page to be pushed therethrough.
