Packaging Box Bending Piece Prevents Incorrect Toner Cartridge Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for toner cartridges do not effectively prevent incorrect removal, leading to inefficiencies in handling and mounting processes due to the lack of clear differentiation between the designated outlet and other end sides, which complicates the handling and mounting of toner cartridges to image forming apparatuses.
Innovation Solution
A packaging box design featuring a tubular side plate, one end side-blocking plate, and another end side-blocking plate, with a bending piece at the other end that can be pressed inward along a breakable line to inhibit movement and distinguish the correct outlet, allowing for visual differentiation between the bubble-containing buffer material and the packaging box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional packaging box without a bending piece is used, then the structure is simple and easy to manufacture, but the toner cartridge can be removed from either end causing handling inefficiency and incorrect removal
Solution Approach 1:
The bending piece is pre-formed as an integral part of the packaging box structure during manufacturing. This preliminary action creates a built-in constraint that guides the toner cartridge to be inserted and removed only from the correct end, eliminating handling errors without requiring complex additional components or assembly steps.
2Reliability
If a bending piece is added to the packaging box to prevent incorrect removal, then incorrect removal is prevented and handling is facilitated, but the device complexity increases
Solution Approach 1:
The bending piece creates a functional segmentation within the packaging box, dividing it into a correct removal end (with the bending piece forming a constraint) and an incorrect removal end (blocked by the bending piece). This segmentation provides clear directional guidance for toner cartridge removal, ensuring reliability while maintaining structural simplicity through a single integrated component.
3Reliability
If the bending piece is made rigid to effectively block incorrect removal, then movement inhibition is effective, but the bending piece cannot be compressed to indicate buffer material location
Solution Approach 1:
The bending piece is designed with specific elastic parameters that allow it to deform under compression force. When the buffer material is compressed, the bending piece flexes to create visible spacing or movement, providing visual feedback about the buffer material's location and compressibility. This parameter change enables the bending piece to simultaneously maintain structural reliability for blocking incorrect removal while providing operational feedback for correct handling.

AI summary
A packaging box includes a bending piece provided at an end part of the other end side of a tubular side plate of the packaging box, and pressed while being surrounded by a breakable line and a bending line so as to be broken and bent to the inside of the box along the breakable line. In the bending state, the bending piece is configured such that its distal end part is positioned at the other end side from a receiving area of an object to be packaged and inhibits movement of the object to be packaged to the other end side.
