Portable bookstand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable bookstands are not suitable for carrying due to their large and heavy design, and they fail to securely support books and prevent pages from flipping arbitrarily.
Innovation Solution
A foldable bookstand with a book back support frame, first and second page fixing frames formed by bending wires, and an 'X'-shaped truss structure that securely supports the book and inhibits page flipping, made of lightweight elastic wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a normal bookstand includes a book support, inclination support means, and page fixing parts, then the book can be securely supported and pages fixed, but the bookstand becomes large and heavy and is not suitable for carrying around
Solution Approach 1:
The patent uses elastic wires with triangular cross-sections to form all structural components (book support, inclination support, page fixing parts). These flexible wire structures provide the necessary mechanical strength and stability while being extremely lightweight compared to traditional rigid materials, directly resolving the contradiction between support reliability and weight reduction.
Solution Approach 2:
The book support and inclination support are designed to be nested within each other when not in use, with the book support fitting inside the inclination support structure. This nesting mechanism dramatically reduces the overall size and volume of the bookstand, making it portable while maintaining full functionality when deployed.
2Weight of moving object
If portable bookstands are made smaller and lighter, then portability is improved, but they fail to securely support books and fix pages
Solution Approach 1:
The elastic wires with triangular cross-sections provide exceptional strength-to-weight ratio, enabling the bookstand to be lightweight yet capable of securely supporting books and fixing pages effectively.
Solution Approach 2:
The triangular cross-section of the elastic wires provides geometric stability and rigidity, allowing the flexible wire structure to maintain its shape and provide reliable support despite the lightweight construction.
3Volume of moving object
If the book support is folded to be adjacent to the inclination support means, then the structure becomes more compact, but the overall bookstand remains large and heavy
Solution Approach 1:
The book support is designed to nest within the inclination support structure when folded, maximizing compactness. Combined with the use of lightweight elastic wires, this nesting design achieves both volume reduction and weight reduction simultaneously.
Solution Approach 2:
The flexible nature of the elastic wire structures allows them to be collapsed and nested efficiently, achieving compact storage volume while the material itself keeps the overall weight minimal.
