Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for disassembling sticky tapes, such as those used in industrial applications, require external heating devices and often fail to efficiently heat the tape within components, leading to thermal damage and prolonged heating times, especially in shielded electronic components.
Innovation Solution
A sticky tape with an adhesive agent layer containing a heating element of high volume resistivity (30 μΩ·cm or more), allowing for resistance heating to melt or soften the adhesive, enabling easy separation, and a method involving electrical connection to a power supply to energize the heating element for rapid disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If external heating devices are used to separate adherends, then heating can be applied, but the heating time becomes prolonged and thermal damage occurs to the adherend
Solution Approach 1:
The heating element is integrated directly into the adhesive agent layer, merging the bonding function and heating function into a single component. This allows the adhesive layer itself to generate heat through resistance heating when voltage is applied, eliminating the need for external heating devices and enabling rapid localized heating without prolonged exposure that causes thermal damage
Solution Approach 2:
The adhesive agent layer contains the heating element and performs heating autonomously when electrical voltage is applied. The system uses its own structure (the adhesive layer with embedded heating element) to provide the heating function, eliminating dependency on external heating equipment and enabling precise control of heating time and temperature
2Temperature
If electromagnetic induction heating or infrared heating is used, then heating can be applied from outside, but the sticky tape within components is not sufficiently heated and it is difficult to adjust heating temperature
Solution Approach 1:
The heating element is embedded specifically within the adhesive agent layer at the location where heating is needed. This localized placement ensures that heat is generated precisely where the sticky tape requires separation, enabling sufficient heating of the tape within components and allowing precise adjustment of heating temperature by controlling the voltage applied to the heating element
Solution Approach 2:
The heating function is merged into the adhesive agent layer itself, making the adhesive layer both the bonding medium and the heating source. This integration ensures reliable and sufficient heating of the sticky tape from within, overcoming the limitation of external heating methods that cannot effectively heat shielded or embedded tapes
3Temperature
If electromagnetic induction heating is used, then heating can be applied, but external heating devices are required which makes disassembling work extensive
Solution Approach 1:
The adhesive agent layer with embedded heating element serves as a self-contained heating system that requires no external heating devices. When voltage is applied to the heating element within the adhesive layer, it autonomously generates heat for separation, dramatically simplifying the disassembly process and eliminating complex external heating equipment
Solution Approach 2:
The heating function is merged into the adhesive agent layer, combining the bonding material and heating source into a single integrated component. This eliminates the need for separate external heating devices and their associated complexity, making the disassembly process simpler and more straightforward
