Palletized Container Clip-Locked Sleeve for Manual-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container systems require manual operation of slide latches for secure attachment of a foldable sleeve to a pallet, which is inefficient and cumbersome.
Innovation Solution
A passive locking mechanism using integrally formed tabs and slots or foldable clips on the sleeve and pallet/covers, allowing secure attachment without manual manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual slide latches are used to attach the sleeve to the pallet, then secure attachment is achieved, but operation efficiency deteriorates due to manual manipulation requirements
Solution Approach 1:
The locking mechanism automatically engages when the sleeve is inserted into the pallet groove. The tabs on the pallet align with and lock into slots on the sleeve without requiring manual manipulation, allowing the system to self-secure during the insertion process.
Solution Approach 2:
The manual slide latch mechanism is replaced with a passive tab-slot locking system. Instead of requiring manual sliding and latching actions, the system uses geometric interlocking features that automatically engage through simple insertion movements.
2Reliability
If manual slide latches are used for attachment, then reliable locking is achieved, but operational complexity increases due to moving components
Solution Approach 1:
The complex moving components of the slide latch mechanism are extracted and replaced with simple geometric features. The locking function is achieved through static tabs and slots rather than dynamic latching mechanisms with multiple moving parts.
Solution Approach 2:
The locking mechanism automatically engages when the sleeve is inserted into the pallet groove. The tabs on the pallet align with and lock into slots on the sleeve without requiring manual manipulation, allowing the system to self-secure during the insertion process.
3Productivity
If passive locking mechanism with tabs and slots is used, then assembly efficiency is improved, but manufacturing complexity increases due to integral tab formation
Solution Approach 1:
The tabs are integrally formed with the pallet structure, combining the pallet body and locking features into a single molded component. This eliminates the need for separate tab components and reduces assembly steps while maintaining manufacturing feasibility through integral forming processes.

AI summary
A molded plastic clip for attachment to the edge of a container sleeve to form part of a passive lock operable between the sleeve and a base structure such as a molded plastic pallet having a peripheral groove for receiving the edge of the panel. The clip comprises a molded plastic body having two generally planar panels joined at one end by a double hinge that allows the panels to be folded into a parallel condition spaced apart by the geometry of the double hinge wherein the inner surfaces of the panels are provided with integral male and female snap lock features and an outer panel is provided with an integral protruding tab feature near the double hinge to fit into a locking slot or opening in the structure groove. The clips are used in multiples.
