Cargo Box Gate Holder for Quick Detachment Without Bolts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles with cargo boxes lack a gate configuration that allows for easy detachment and attachment without the need for manual tightening or loosening of bolts, compromising operational efficiency.
Innovation Solution
A work vehicle design featuring a cargo box with a gate that is swingable and detachable, utilizing a shaft and support mechanism with a holder that can be manually operated between positions to facilitate easy attachment and detachment, and includes urging sections to prevent accidental detachment during travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gate is detachable from the floor to improve ease of operation and maintenance, then the coupling between the shaft and support must be reliable to prevent accidental separation
Solution Approach 1:
The holder acts as an intermediary component between the shaft and support. It provides a manual locking mechanism that maintains reliable coupling during normal operation while allowing intentional detachment when needed. The holder engages with both the shaft and support structures, creating a three-component coupling system that balances security with operability.
2Ease of manufacture
If the gate can be easily detached from the floor for maintenance, then the shaft and support coupling must remain secure during operation
Solution Approach 1:
The holder serves as a mediating component that strengthens the shaft-support connection during operation while allowing easy maintenance detachment. It provides a dedicated coupling interface that is stronger than direct shaft-support contact, yet can be manually engaged and disengaged for maintenance purposes.
Solution Approach 2:
The coupling system is segmented into three distinct components: the shaft, the holder, and the support. This segmentation allows the holder to specialize in providing both strong mechanical coupling and easy maintenance access, rather than requiring the shaft or support to perform both functions alone.
3Reliability
If the holder allows manual operation between locked and unlocked positions, then it prevents accidental separation while permitting intentional detachment
Solution Approach 1:
The holder is designed to be manually operated without requiring additional tools or complex actuation mechanisms. The operator can directly engage and disengage the holder by hand, making the system self-sufficient for its locking function while minimizing the complexity of the control mechanism.

AI summary
With a shaft (16,27) and a support (14a, 33a, 34a) attached to each other, a gate (10, 11) is swingable about a horizontal axis (P1,P3) between a standing position (A11,A21) and an open position (A12,A22) and detachable from a floor (9). A holder (17,29) is included that is manually operable between (i) a first position (B 11,B21), in which the holder (17,29) prevents the shaft (16,27) and the support (14a, 33a, 34a) from becoming apart from each other and holds the gate (10, 11) in such a manner that the gate (10, 11) is swingable about the axis (P1,P3), and (ii) a second position (B12,B22), in which the holder (17,29) allows the shaft (16,27) and the support (14a, 33a, 34a) to become apart from each other and allows the gate (10, 11) to be detached from the floor (9).
