Fiber Reinforced Tank Surface Shaving for Label Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-pressure tanks with fiber reinforced resin layers have rough surfaces due to irregular resin bleeding, making it difficult to attach labels stably and accurately, requiring manual shaving and additional adhesive application, which increases workload and generates unnecessary waste.
Innovation Solution
The method involves winding fiber bundles in multiple layers around a liner with varying pitch widths to create gaps, allowing for controlled resin bleeding and forming a flat surface, and optionally applying a light reflecting layer to facilitate precise shaving and label attachment using laser determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fiber bundles are wound around the liner to form a fiber reinforced resin layer, then the tank gains structural strength, but the surface becomes rough due to irregular resin bleeding
Solution Approach 1:
The patent applies preliminary action by performing shaving processing on the protrusions before label attachment. The tip ends of the protrusions on the surface resin layer are shaved off to create a substantially flat surface, ensuring stable label attachment while maintaining the structural integrity provided by the fiber reinforced resin layer
2Stability of the object's composition
If the surface is left rough with projections, then the fiber reinforced resin layer maintains its structural integrity, but label attachment becomes unstable
Solution Approach 1:
The patent performs preliminary shaving of the protrusion tip ends to create a flat surface for label attachment. This preliminary action removes the irregularities that would cause unstable attachment while preserving the underlying fiber reinforced structure's integrity
3Reliability
If manual shaving is performed to create a flat surface, then label attachment stability improves, but workload increases and waste is generated
Solution Approach 1:
The patent replaces manual mechanical shaving with automated laser processing. The laser beam automatically removes the protrusions to create a flat surface, eliminating the need for manual operation and reducing waste generation from excessive material removal
Solution Approach 2:
The patent uses laser scanning to create a digital model of the surface protrusions before removal. This copying approach allows precise identification of protrusion locations and volumes, enabling selective removal only where needed and minimizing waste

AI summary
Provided are a method for producing a tank with an outer surface profile that allows a thin label to be easily and firmly attached to a surface thereof, and also such a tank. The method for producing the tank, which includes winding fiber bundles containing an uncured resin component in multiple layers around the outer surface of a liner in a first pitch width so as to form a fiber reinforced resin layer, further includes: winding fiber bundles in a second pitch width wider than the first pitch width so as to form a gap with a required width where no fiber bundle is present between adjacent fiber bundles in winding the fiber bundles to form an outermost layer; shaving off a tip end portion of a projection made of a resin that has cured after bleeding into the gap, with a portion of the projection in a predetermined height left unshaved; and attaching a label to a surface obtained through shaving off the tip end portion.
