Data Page Tab Bonding via Resistive Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data pages for book-like documents face challenges in forming reliable connections between individual pages and tab elements, particularly in avoiding damage during ultrasonic welding and ensuring secure anchoring without visible traces or markings.
Innovation Solution
Incorporating an electrical conducting element, such as a linear metal wire or shape memory alloy, between the page and tab elements in the overlapping area to facilitate direct heat input for melting and forming connections, allowing for a mechanical or material bond without requiring opposing movement, and enabling secure anchoring through positive engagement or adhesive mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ultrasonic welding is used to join the tab section to the individual page, then a material bond can be formed, but damage may occur to the materials due to opposing movement during welding
Solution Approach 1:
The patent replaces the ultrasonic welding process (mechanical vibration-based) with direct heat input through an electrical conductor. This substitution eliminates the opposing movement between anvil and sonotrode that causes material damage, while still achieving a strong material bond through controlled melting and fusing of the tab section and individual page materials.
Solution Approach 2:
The electrical conductor acts as an intermediary element that introduces heat directly at the connection point between the tab section and individual page. This mediator enables the bonding process without requiring the tab and page to move against each other, thus avoiding damage while achieving reliable attachment.
2Reliability
If ultrasonic welding is used to create a material bond, then secure anchoring is achieved, but visible traces or markings may appear on the document surface
Solution Approach 1:
The patent applies local quality by concentrating the heating action precisely at the connection point where the tab section meets the individual page. The electrical conductor delivers heat only where needed for bonding, leaving the surrounding document surfaces unaffected and free from visible traces or markings, thus maintaining aesthetic appearance while ensuring secure anchoring.
3Ease of manufacture
If direct heat input is applied through an electrical conductor, then opposing movement between layers is avoided, but additional components are required
Solution Approach 1:
The electrical conductor serves multiple functions: it acts as both the bonding agent (by providing direct heat input) and the anchoring mechanism (by being embedded in the connection point). This multi-functionality reduces the need for separate components for heating and bonding, simplifying the overall process despite the addition of the conductor element.
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
This method allows for a strong, flexible, and visually unobtrusive connection between the page and tab elements, ensuring stability and security while avoiding damage during the bonding process and maintaining the document's appearance.
Implementation Method 1
at least one electrical conducting element, in particular a linear metal wire or shape memory alloy, between the page (27) and the tab elements (32) in the overlapping area (30) to facilitate direct heat input for melting and forming connections
Implementation Method 2
This enables the at least one electrical conductor to be energized to create a material bond, a mechanical bond, or a combination of both between the tab section of the at least one tab element and the individual side, thus resulting in direct heat input at the crosslinking point or the connection point. This allows the individual side or the tab section of the tab element, or both, to melt or fuse together
