Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tape application devices are inconvenient and prone to errors, such as self-rolling or sticking, leading to waste, as they require manual handling and lack efficient mechanisms for precise application.
Innovation Solution
A manually operated adhesive tape application device with a movable and stationary portion that performs a superimposed rotational-linear or swivelling-linear movement, featuring a clamping device, pressing member, and cutting mechanism to ensure precise and waste-free application of adhesive tape, with adhesion-reducing surfaces to prevent sticking and a flexible projection for uniform pressure on irregular surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual handling of adhesive tape is used, then the device structure can be simple, but the application precision deteriorates and waste increases due to self-rolling or sticking
Solution Approach 1:
The device is divided into distinct functional modules: a supply unit for holding the adhesive tape roll, a pulling mechanism with stamps for extracting tape sections, a cutting device for severing the tape, and an application device for pressing the tape onto the object. This segmentation allows each module to perform its specific function precisely while keeping the overall device manageable in complexity
Solution Approach 2:
The stamping element automatically pulls the adhesive tape from the roll and the cutting device automatically severs the tape section during the stamping motion. The adhesive tape is fed and cut without requiring manual intervention between operations, enabling continuous precise application while maintaining relatively simple device structure
2Device complexity
If manual pulling and severing of adhesive tape is performed, then the device can be simple, but reliability deteriorates due to risk of self-rolling or sticking
Solution Approach 1:
The stamping element acts as an intermediary between the adhesive tape roll and the application surface. It controls the extraction, transport, and delivery of the tape section throughout the stamping motion, preventing uncontrolled self-rolling or sticking. The cutting device similarly acts as an intermediary to ensure clean severing at the correct position
Solution Approach 2:
The adhesive tape is pulled and positioned on the stamping element before the stamping motion begins. The cutting device is positioned and ready to sever the tape at the precise moment needed. This preliminary preparation ensures that the tape is controlled and ready for reliable application without spontaneous rolling or sticking
3Device complexity
If adhesive tape is applied without adhesion-reducing surfaces, then the device structure can be simpler, but the tape sticks to the device surfaces causing waste and operational failures
Solution Approach 1:
Adhesion-reducing surfaces are applied selectively to specific contact areas of the device where adhesive tape interacts with moving parts, such as the stamping element and guide surfaces. This localized treatment prevents sticking in critical areas while maintaining the overall simplicity of the device structure without requiring coating the entire device
4Manufacturing precision
If uniform pressure is applied to irregular surfaces, then application quality improves, but device complexity increases due to need for flexible projection
Solution Approach 1:
The application device incorporates a flexible projection or compliant element that can deform to conform to irregular surface geometries. This flexible component distributes the pressing force uniformly across the adhesive tape and the object surface, ensuring quality application on non-flat surfaces while adding minimal structural complexity
