Corner Board with Integrated Flaps for Staple-Free Container Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional corner boards for container stacks require additional materials like staples or tape for attachment, which are time-consuming, costly, and pose safety risks, and can damage containers or their contents during handling and transportation.
Innovation Solution
A corner board design featuring bendable flaps created by slits at one end, allowing it to be placed on containers without additional attachment materials, using a manufacturing process that cuts and forms the flaps simultaneously with the board stock, eliminating the need for staples or tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If staples or tape are used to attach corner boards to container stacks, then the corner boards can be securely fixed in place, but additional materials are required which increases cost, time consumption, and safety risks
Solution Approach 1:
The patent removes the separate attachment materials (staples, tape) from the system by integrating the attachment function directly into the corner board structure through bendable flaps that fold over the container edges, eliminating the need for additional fastening components
Solution Approach 2:
The corner board's own structure (the bendable flaps formed from the board material itself) performs the attachment function, allowing the corner board to secure itself to the container stack without requiring external attachment materials or tools
2Reliability
If staples or tape are used to attach corner boards, then secure fixation is achieved, but the process becomes time-consuming and requires additional materials
Solution Approach 1:
The patent eliminates the time-consuming processes of stapling or taping by removing these attachment methods entirely, replacing them with a simple fold-and-place operation using the integrated bendable flaps
Solution Approach 2:
The corner board automatically secures itself through the mechanical action of folding the flaps over the container edges, requiring no additional tools, materials, or complex procedures, thereby dramatically increasing attachment speed
3Reliability
If staples are used to attach corner boards, then secure fixation is achieved, but safety risks arise from protruding staples during removal
Solution Approach 1:
The patent removes the hazardous protruding staples from the system entirely by replacing the stapling attachment method with bendable flaps that fold over the container edges, eliminating the safety risk of exposed fasteners during handling and removal
Solution Approach 2:
The corner board's integrated flap structure provides secure attachment through its own geometry without requiring external fasteners that could protrude or cause injury, making the system inherently safer during installation and removal
4Reliability
If staples or tape are used to attach corner boards, then secure fixation is achieved, but damage may occur to container exteriors or contents
Solution Approach 1:
The patent eliminates the damage-causing attachment materials (staples that can pierce contents, tape that can tear surfaces) by replacing them with bendable flaps that apply gentle distributed pressure through folding, preventing damage to container exteriors and contents
Solution Approach 2:
The corner board secures itself through the mechanical advantage of folded flaps that conform to the container edges, providing secure attachment through geometry rather than penetrative or adhesive forces that could damage the container

AI summary
A corner board includes first and second sides, each including a board material; a bend between first and second sides, joining the sides together; and a slit adjacent to a first end of the corner board forming a first flap adapted to place the corner board on a container or a stack of containers or otherwise couple the corner board to horizontal and vertical surfaces of the container or stack of containers. A method of manufacturing a corner board includes bending a board stock to form first and second sides of the corner board with an angle therebetween; cutting the board stock into fixed lengths, the bent and cut board stock forming the corner board; and forming a slit near a first end of the corner board, in which the slit creates a first flap adapted to couple the corner board to a container or a stack of containers.
