Tape Applicator Split Wiper for Uneven Carton Flaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape applicators struggle to effectively apply pressure-sensitive adhesive tape to cartons that are under-packed or over-packed, where the flaps are not level with respect to each other, leading to incomplete sealing.
Innovation Solution
A tape applicator with a split wiper that includes independently flexing wiper portions to apply pressure to the tape on uneven carton flaps, combined with a cutting blade for precise tape application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-piece wiper is used, then the structure is simple, but it cannot adapt to uneven carton flaps when cartons are under-packed or over-packed
Solution Approach 1:
The wiper is divided into multiple independent segments that can flex and move relative to each other. This segmentation allows each segment to independently adapt to the contour of uneven carton flaps, solving the adaptability problem while keeping each individual segment relatively simple in structure.
Solution Approach 2:
The wiper segments are designed to be dynamic rather than rigid, allowing them to flex and conform to the varying heights and angles of carton flaps. This dynamic capability enables the wiper to maintain contact with uneven surfaces without requiring a complex adjustable mechanism.
2Manufacturing precision
If pressure is applied uniformly across the wiper, then the structure is simple, but it cannot provide consistent tape application on uneven surfaces
Solution Approach 1:
By segmenting the wiper into multiple independent sections, each segment can independently apply pressure to its corresponding portion of the carton flap. This ensures uniform pressure distribution across uneven surfaces without requiring a complex active pressure control system.
Solution Approach 2:
The wiper segments are designed with varying physical parameters such as flexibility, thickness, or material properties to optimize pressure application. This passive parameter adjustment allows consistent tape application on uneven surfaces without adding complex active control mechanisms.
3Adaptability or versatility
If the wiper material is rigid, then it provides structural stability, but it cannot conform to uneven carton flaps
Solution Approach 1:
The wiper is constructed as multiple rigid or semi-rigid segments connected by flexible joints. Each segment maintains its structural stability, while the connections between segments provide the necessary flexibility to conform to uneven carton flaps.
Solution Approach 2:
The connections between wiper segments utilize flexible elements such as thin films, bellows, or articulated joints that allow the rigid segments to move relative to each other. This combination maintains the structural integrity of individual segments while enabling overall adaptability to uneven surfaces.

AI summary
A tape applicator consistent with the present disclosure may include a tape applicator configured for applying a tape, such as a pressure sensitive adhesive tape to a carton (e.g., for sealing and/or assembling the carton). One or more rollers may be utilized to aid in applying the pressure sensitive adhesive tape to a carton. Furthermore, a wiper aids in applying pressure sensitive adhesive tape to a carton (e.g., before and/or after the one or more rollers). The wiper may be a split wiper having a first portion and a second portion, which allows for applying adhesive tape to a carton when the carton is under-packed or over-packed, and thus, the flaps of the carton are not level with respect to each other (e.g., the edges are not located in the same plane).
