Self-adjusting Laminar Book Protector with Biodegradable Adhesive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current book protectors are not eco-friendly, as they are made of plastic materials that pollute the environment and cause damage to book covers when removed, and they often do not accommodate books of different sizes effectively.
Innovation Solution
A self-adjusting, non-plastic laminar protector made from cellulose acetate film or vegetable parchment with adhesive areas covered by siliconized material, allowing it to fit various book sizes without damaging the covers, using reusable water-based adhesive and a structural design with inner bands for adjustable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic-based adhesive protectors are used, then book covers are protected from wear, but the environment is polluted and the book covers are damaged when removed
Solution Approach 1:
The adhesive is extracted from direct contact with the book cover by placing it on the inner face of the laminar body rather than on the outer surface. This allows the adhesive to be removed with the laminar body itself, preventing damage to the book cover while maintaining the protective function during use
Solution Approach 2:
The material composition is changed from plastic-based to cellulose acetate or vegetable parchment, which are biodegradable and environmentally friendly. This parameter change maintains the protective function while eliminating environmental pollution and reducing harm to book covers upon removal
2Reliability
If fixed-size protectors are used, then book covers are well protected, but they cannot accommodate books of different sizes
Solution Approach 1:
The laminar body incorporates adjustable elements such as elastic bands or flexible components that allow the protector to dynamically adapt to different book sizes. This enables a single protector design to maintain reliable protection across multiple book dimensions
Solution Approach 2:
The protector is designed with universal adaptability features including adjustable straps, elastic components, or modular elements that allow it to serve multiple book sizes and formats, eliminating the need for multiple fixed-size protectors
3Adaptability or versatility
If reusable adhesive is used, then the protector can be removed and reapplied, but the adhesive may damage book covers upon removal
Solution Approach 1:
The adhesive is positioned on the inner face of the laminar body rather than in direct contact with the book cover. When the protector is removed, the adhesive comes away with the laminar body, allowing reuse without damaging the book cover while maintaining reapply capability
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
The protector is eco-friendly, compostable, and can be removed without damaging the book covers, accommodating different book sizes through its adjustable design and reusable adhesive, addressing the environmental and size compatibility issues of existing protectors.
Implementation Method 1
consisting of a laminar body that can be adjusted as a lining for book covers to prevent deterioration by means of attachment with adhesive
Implementation Method 2
these areas are covered with a layer of protective siliconized paper
Implementation Method 3
it is made of a non-plastic material derived from wood and of offering a structural configuration... manufactured from a cellulose acetate film or vegetable parchment

AI summary
It consists of a protector for books, notebooks, and the like that is made up of a laminar body that fits book covers like a lining. It has the particularity of being made of an ecological, compostable material where that laminar body (1) consists of an outer sheet (10) that is rectangular in shape, along with two inner bands (11) that are positioned on both sides on the inner face of that outer sheet (10) and are joined by their ends to the edges that shape the longer sides (10a) of the outer sheet (10). This way, the covers (2) of the book can be inserted between the outer sheet (10) and those inner bands (11). The system includes an adhesive strip of area located at one of the two lateral ends of the outer sheet (10) that attaches to one of the inner strips (11) while not coming into contact with the covers (2) of the book (3).
