Forklift Scrap Box with Hinge-Based Reversing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scrap boxes require workers to frequently get on and off a forklift during loading, unloading, and discharging, leading to increased workload and safety concerns, especially when handling infectious materials, due to insufficient rotation angle and complex structures.
Innovation Solution
An article reversing/discharging box with a reversing mechanism that allows the box to be turned using a forklift's forks, eliminating the need for manual operation by incorporating fixed and movable hook members and a hinge-based reversing mechanism, enabling complete discharge without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the box main body is made turnable about the distal end portion of the bottom plate by the reversing member, then the article can be completely discharged without manual intervention, but the device complexity increases due to the reversing mechanism
Solution Approach 1:
The box main body is inverted by rotating it about the distal end portion of the bottom plate as a fulcrum. The reversing member facilitates this inversion operation, allowing articles to be completely discharged from the box without manual intervention. This inversion approach transforms the discharge process from a complex manual operation to a simple mechanical rotation.
Solution Approach 2:
The reversing mechanism enables the box to perform its own discharge operation without external manual assistance. By rotating the box about the bottom plate's distal end portion, the system achieves self-service discharge functionality, eliminating the need for workers to manually scrape or remove remaining articles.
2Ease of operation
If fixed hook members and movable hook members are used with the forklift forks, then the worker can remain on the forklift during discharging operations, but the device complexity increases due to the dual hook member system
Solution Approach 1:
The hook members system includes both fixed hook members attached to the box and movable hook members that can move with the forklift forks. This dynamic configuration allows the forks to engage with the movable hooks while the fixed hooks provide stable attachment points, enabling the worker to remain on the forklift during operations without excessive structural complexity.
3Productivity
If the box main body is reversed by rotating about the distal end portion of the bottom plate, then the rotation angle is sufficient for complete article discharge, but the manufacturing precision requirements increase for the reversing mechanism
Solution Approach 1:
The reversing mechanism merges the rotation function with the existing forklift lifting and positioning capabilities. By using the distal end portion of the bottom plate as a fulcrum and integrating the reversing member with the hook members system, the design achieves sufficient rotation angle for complete discharge while leveraging existing structural elements to reduce manufacturing precision requirements.

AI summary
[Object] To provide an article reversing/discharging box and a method of using the article reversing/discharging box, capable of reducing a load of a worker, allowing an article discharging work without the worker getting off the forklift, and being manufactured at low cost. [Solution] An article reversing/discharging box 1 includes a box main body 2 that accommodates scrap, hook members 3, 4 having insertion holes 3a, 4a through which forks of a forklift are inserted above the box main body 2, and a reversing mechanism 5 capable of reversing the box main body 2. The reversing mechanism 5 includes a bottom plate 6 integrally extending from a lower end of the movable hook member 4 along the bottom surface 2d, and a hinge 7 provided at a distal end portion of the bottom plate 6. When the forks are inserted into the insertion holes 4a of the movable hook member 4 and the forks are removed from the insertion holes 3a of the fixed hook members 3, the box main body 2 is turnable about the distal end portion of the bottom plate 6 by the hinge 7.
