Hanging Bag Frame Locking Element with Inclined Spreading Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hanging bag frames for overhead conveyors are not economically efficient due to complex mechanisms and require multiple manipulations for unloading, which complicates the unloading process.
Innovation Solution
Integration of the spreading mechanism with the locking mechanism on the joint mechanism, utilizing inclined surface sections on the locking element to automatically unfold the lower frame parts when transitioning from the locked to the release position, reducing the number of components and simplifying the unloading process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking mechanism and spreading mechanism are provided as separate components, then the locking function is reliable, but the device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent combines the locking mechanism and spreading mechanism into a single integrated joint mechanism. The locking element includes both a locking portion that engages with the frame part to secure it, and an inclined surface portion that acts as the spreading mechanism. When the locking element pivots from the locked position to the release position, the inclined surface automatically pushes the frame part to unfold, thus merging two functions into one component structure.
Solution Approach 2:
The locking element serves multiple functions: it provides locking engagement through its locking portion, provides spreading force through its inclined surface portion, and enables automatic unfolding of the frame part. This multi-functional design eliminates the need for separate spreading mechanism components, reducing overall device complexity while maintaining both locking reliability and spreading capability.
2Reliability
If multiple separate mechanisms are used for locking and spreading, then each function can be optimized independently, but the number of components increases and manufacturing cost rises
Solution Approach 1:
The patent merges the locking mechanism and spreading mechanism into a single integrated joint mechanism. The locking element includes both a locking portion that engages with the frame part to secure it, and an inclined surface portion that acts as the spreading mechanism. When the locking element pivots from the locked position to the release position, the inclined surface automatically pushes the frame part to unfold, thus merging two functions into one component structure.
Solution Approach 2:

This multi-functional design eliminates the need for separate spreading mechanism components, reducing overall device complexity while maintaining both locking reliability and spreading capability.
3Ease of operation
If the locking mechanism requires separate actuation from the spreading mechanism, then each function can be controlled independently, but the number of manipulations increases and unloading process becomes complex
Solution Approach 1:
The patent combines the locking mechanism and spreading mechanism into a single integrated joint mechanism. The locking element includes both a locking portion that engages with the frame part to secure it, and an inclined surface portion that acts as the spreading mechanism. When the locking element pivots from the locked position to the release position, the inclined surface automatically pushes the frame part to unfold, thus merging two functions into one component structure.
Solution Approach 2:
The inclined surface on the locking element is pre-configured to automatically push the frame part into the unfolded position as the locking element pivots from locked to release position. This preliminary action of spreading occurs simultaneously with the unlocking action, eliminating the need for separate spreading manipulation and simplifying the unloading process.
