Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for disassembling adhesive members using thermal fusion or decomposition are inefficient, leading to wasted energy and materials, and lack security against unauthorized disassembly.
Innovation Solution
A debonding apparatus and system that includes a debonder and a controller, remotely activated by a terminal apparatus, using solvents, heat, or light to selectively target and debond adhesive members within an object, with authentication to ensure authorized disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If thermal fusion or decomposition methods are used to disassemble adhesive members, then the adhesive member can be debonded, but energy is wasted and the process is inefficient
Solution Approach 1:
The patent applies local quality by using a debonder that can be selectively positioned and activated at specific locations within the object. The controller receives authentication information and activates the debonder only when authorized, enabling localized debonding of adhesive members without heating or acting on the entire object. This targeted approach reduces energy waste while maintaining efficient debonding performance.
2Reliability
If conventional thermal debonding methods are used, then adhesive members can be removed, but there is no security against unauthorized disassembly
Solution Approach 1:
The patent implements feedback through the controller that receives authentication information from a terminal apparatus before activating the debonder. This authentication mechanism provides feedback control, ensuring that the debonding operation only occurs when authorized. The system maintains operational simplicity by automating the authentication and activation process through wireless communication.
3Ease of operation
If the debonder is activated without authentication, then debonding operation is simple, but unauthorized disassembly can occur
Solution Approach 1:
The patent introduces an intermediary authentication mechanism between the terminal apparatus and the debonder activation. The controller acts as a mediator that receives authentication information wirelessly before permitting the debonder to operate. This intermediary layer maintains ease of operation through automated wireless authentication while preventing unauthorized disassembly by requiring valid authentication credentials.

AI summary
A debonding apparatus includes a debonder and a controller that are located inside an object including multiple adhered members adhered by an adhesive member. The debonder is configured to be operatable to debond the adhesive member by acting on the adhesive member. The controller is configured to activate the debonder, based on a debonding instruction received from a terminal apparatus located outside the object.
