Solution Overview
Problem
Existing adhesive application apparatuses face issues with tape slackening during trial applications, leading to entanglement with peripheral parts and temporary suspension of the adhesive application line.
Innovation Solution
An adhesive application apparatus with a suction unit that conducts a suction operation on the trial application stage, using a porous adsorptive pad to maintain a neat adhesive droplet shape and facilitate smooth suction without disrupting the main adhesive application process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a trial application tape is used to conduct trial application, then the trial application can be carried out, but the tape may slacken and get entangled with peripheral parts
Solution Approach 1:
The patent extracts the trial application function from the main adhesive application line by providing a separate trial application stage with its own application unit and suction unit. This allows trial applications to be conducted independently without affecting the main production line, and the trial adhesive is removed through a dedicated suction system rather than being integrated into the main tape handling system.
Solution Approach 2:
The patent introduces a suction unit as an intermediary mechanism to remove trial adhesive from the trial application stage. This suction unit acts as a mediator between the trial application process and the main adhesive application line, allowing clean removal of trial adhesive without interfering with the main production process or causing tape entanglement.
2Measurement precision
If trial application is conducted on the adhesive application line, then adhesive quantity can be determined, but the adhesive application line must be temporarily suspended
Solution Approach 1:
The patent segments the adhesive application system into a main adhesive application line for production and a separate trial application stage for measurement and calibration. The trial application stage includes its own application unit that can be independently operated, allowing adhesive quantity determination without suspending the main production line.
Solution Approach 2:
The patent enables continuous operation of the adhesive application line by conducting trial applications on a separate stage. The main production line continues uninterrupted while the trial application stage performs adhesive quantity determination, ensuring that useful action (production) continues without interruption.
3Ease of operation
If trial application tape is used, then trial application can be performed, but slack in the tape hinders the taking-up operation
Solution Approach 1:
The patent replaces the mechanical tape handling and taking-up system with a suction-based removal system for trial adhesive. Instead of relying on a complex tape reeling and tensioning mechanism, the trial adhesive is removed through a suction unit that actively draws the adhesive away from the trial application stage, simplifying the overall system.
