Pliable Dispenser Web for Even Shoe Adhesive Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adhesive applicators for shoe components fail to apply adhesive evenly due to the use of hard roller members that do not deform in compliance with the topology of the attachment region, leading to uneven adhesive distribution.
Innovation Solution
An adhesive applicator featuring a rotatable actuation axle, hub units, elastic members, and a pliable dispenser web that deforms in compliance with the topology of the shoe component's attachment region, ensuring continuous and even adhesive application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hard roller members are used for adhesive application, then adhesive application efficiency is improved, but adhesive distribution uniformity deteriorates
Solution Approach 1:
The patent replaces hard roller members with a pliable dispenser web that can deform to conform to the topology of the attachment region. This flexible web material allows the adhesive to be applied evenly across complex surfaces while maintaining application efficiency, directly resolving the contradiction between productivity and manufacturing precision.
Solution Approach 2:
The patent changes the physical parameter of the adhesive application surface from hard and rigid to pliable and deformable. By making the dispenser web flexible, it can adapt its shape to match the attachment region topology, ensuring uniform adhesive distribution without sacrificing application speed.
2Manufacturing precision
If pliable dispenser web is used for adhesive application, then adhesive distribution uniformity is improved, but structural stability deteriorates
Solution Approach 1:
The patent divides the dispenser web into multiple discrete rollers arranged along the rotation axis. Each roller segment can independently deform to conform to local surface features while the collective arrangement maintains overall structural stability during rotation and operation.
Solution Approach 2:
The patent employs a dynamically flexible dispenser web that can adapt its shape during operation. The web's pliability allows it to deform under pressure to match the attachment region topology, yet it maintains sufficient structural integrity to rotate and perform its adhesive application function effectively.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adhesive applicator ensures even and continuous adhesive application to the shoe component's attachment region by utilizing the elastic properties of the pliable dispenser web, which conforms to the topology, thereby improving the adhesive distribution.
Implementation Method 1
Each of the elastic members extends along a lengthwise axis to terminate at a first end region and a second end region, and is stretchable lengthwise so as to have a radial elastic force relative to the lengthwise axis
Implementation Method 2
the pliable dispenser web is deformed in compliance with a topology of the attachment region, thereby allowing the spread adhesive to be continuously and evenly applied to the attachment region
Implementation Method 3
The first and second end regions are configured to be in frictional engagement with the first and second marginal portions, respectively, so as to permit the elastic members to rotate with the first and second hub units about the rotation axis

AI summary
An adhesive applicator includes an actuation axle, a first hub unit, a second hub unit, a plurality of elastic members, and a pliable dispenser web. The first and second hub units are mounted on the actuation axle to be spaced apart from each other, and to rotate with the actuation axle about a rotation axis. Each of the elastic members is disposed between the first and second hub units, and has a radial elastic force relative to the rotation axis. The pliable dispenser web is configured to wrap around the elastic members, and can be deformed in compliance with a topology of an attachment region of a shoe component against the radial elastic force.
