Lifting Skid Depth Limiter for Precise Fork Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hoist systems in logistics face challenges in ensuring precise and safe insertion of runners into transport items, leading to risks of accidents and injuries due to protruding runner tips and potential tipping of goods, as the insertion depth cannot be accurately monitored, requiring time-consuming and precise manual adjustments.
Innovation Solution
A device with a fastening mechanism that includes a rear stop to limit the insertion depth of the runners, combined with a front stop and longitudinal struts to secure the position, and optionally a tilting unit for ergonomic handling, allowing for safe and precise positioning of goods without runner tips protruding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator manually positions the skids without a limiting device, then the lifting device can be used for various loads, but the insertion depth cannot be monitored leading to protruding skid tips and safety hazards
Solution Approach 1:
A limiting device is introduced as an intermediary component between the skids and the load. This device includes a front stop and a rear stop that define a specific distance, automatically controlling the insertion depth of the skids when the load is placed on the lifting device, thereby eliminating safety hazards without requiring complex active control systems
Solution Approach 2:
The limiting device is designed to be self-regulating through its mechanical structure. The front stop and rear stop automatically establish the correct insertion depth through their fixed distance relationship, eliminating the need for operator judgment or complex monitoring systems while ensuring consistent safe operation
2Measurement precision
If the operator constantly checks the skid position before lifting, then the insertion depth can be monitored, but the operation becomes time-consuming
Solution Approach 1:
The limiting device pre-establishes the correct insertion depth through its mechanical structure (front stop and rear stop distance) before the lifting operation begins. This eliminates the need for constant checking during operation, as the correct position is automatically determined by the physical constraints of the device itself
Solution Approach 2:
The system performs self-monitoring through its mechanical design. The fixed distance between front and rear stops automatically ensures correct insertion depth without requiring external monitoring or time-consuming checks by the operator, thereby maintaining both precision and productivity
3Stability of the object's composition
If the skids are inserted too deep, then the load can be securely gripped, but the skid tips protrude causing safety risks
Solution Approach 1:
The limiting device acts as an intermediary that mediates between the need for deep insertion (for secure grip) and the need to prevent protrusion (for safety). The front stop and rear stop define a precise insertion depth that achieves both objectives simultaneously
Solution Approach 2:
The invention changes the parameter of insertion depth from being variable (determined by operator judgment) to being fixed (determined by the mechanical distance between front and rear stops). This parameter change ensures that the skids are inserted deep enough for secure grip but not so deep that tips protrude
4Productivity
If the skids are inserted too shallow, then the operation is faster, but the load may tip or slip over the skid tips
Solution Approach 1:
The limiting device serves as a mechanical intermediary that guarantees adequate insertion depth. The front stop prevents the skids from being inserted too shallowly, while the rear stop ensures they don't go too deep, automatically achieving the optimal insertion depth for load stability without slowing down operations
Solution Approach 2:
The correct insertion depth is pre-determined by the mechanical structure of the limiting device. This preliminary setup ensures that during actual operation, the skids are automatically positioned at the correct depth for load stability without requiring time-consuming adjustments or checks
