Corrugated Angle Board Blank with Tape for Lightweight Shipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner boards made of paper or paper and foam are heavy, limiting the amount that can be shipped on a truck and risking the stability of palletized loads during transport.
Innovation Solution
A blank for making an angle board using corrugated material with a longitudinally disposed groove and a double coated tape strip for bending into an angle shape, allowing for self-adhesion and light weight construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If corner boards are made of paper or paper and foam layers, then they provide durable edge protection and load support, but they become relatively heavy and restrict shipping capacity
Solution Approach 1:
The patent changes the material parameters by using corrugated board instead of solid paper or paper-foam laminates. The corrugated structure provides comparable strength and protection while significantly reducing weight, allowing trucks to be filled to volume capacity without exceeding weight limits.
Solution Approach 2:
The corrugated board structure inherently contains air pockets and voids within its layered construction, creating a porous-like structure that reduces density and weight while maintaining structural integrity and protective function for edge protection applications.
2Stability of the object's composition
If multiple layers of paper are laminated together to form corner boards, then they provide rigid structure and load support, but they become heavy and occupy excessive shipping weight capacity
Solution Approach 1:
The invention changes the structural parameters by adopting corrugated board construction with specific flute patterns and layer configurations that provide necessary rigidity and stability while minimizing weight. The corrugated structure achieves structural integrity through its geometric design rather than relying on heavy material mass.
3Reliability
If strapping materials are used to secure corner boards to palletized stacks, then they provide load stability, but they can slide out of place during transport
Solution Approach 1:
The corner board design incorporates self-adhering features through the double-coated tape strip that bonds the corrugated layers together. This self-service mechanism eliminates the need for separate strapping materials that can fail, as the corner board maintains its structural integrity and load-securing function through its own inherent adhesive bonding.
Solution Approach 2:
The patent merges the corner board structure with the bonding function by integrating the double-coated tape strip directly into the corner board construction. This combination eliminates the need for separate strapping materials, as the corner board itself provides both structural support and load-securing capabilities through its adhesive-bonded layers.

AI summary
A blank of flat corrugated board is formed with a longitudinal perforation or crease to enable folding into an angle board. A double coated tape strip is adhered on the flat body opposite the perforation or over the crease and a release layer is disposed over said tape strip. After removal of the release layer, the flat board may be folded into an angle board shape with the adhesive maintaining the folded sections of the flat body together.
