Packaging Container Locking Mechanism for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging containers with base and casing parts are difficult to handle due to inadequate fixation mechanisms, leading to instability and movement during use.
Innovation Solution
Incorporating locking parts on the base part that project into recesses on the casing part, allowing for secure engagement and stabilization in multiple directions, enhancing handling and stability by forming stop elements and allowing for easy assembly from a flat storage position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the shell is moved from a flat storage position into the operating position, then space-saving storage is enabled, but the fixation mechanism becomes inadequate leading to instability and movement during use
Solution Approach 1:
The base part is segmented into multiple functional elements: a bottom wall, an outer edge projecting upwards, and at least one locking part with a projection. This segmentation allows the base to provide both structural support and secure fixation mechanisms independently, resolving the contradiction between compact storage and stable operation.
Solution Approach 2:
The locking part with its projection is pre-formed on the base part before assembly. When the shell is erected from its flat storage position, the projection automatically engages with the recess on the side wall, providing preliminary fixation that prevents instability and movement during the transition to and during the operating position.
2Stability of the object's composition
If locking parts are added to secure the shell to the base, then stability is improved, but the device complexity increases
Solution Approach 1:
The locking part is merged with the base part as an integral structure. The projection of the locking part is formed directly on the base part, combining the base's support function with the locking function in a single unified component. This merging provides stable fixation without increasing overall device complexity.
Solution Approach 2:
The locking mechanism is designed to be self-servicing through the automatic engagement of the projection with the recess on the side wall. When the shell is erected, the projection naturally inserts into and locks within the recess without requiring additional fasteners, tools, or complex assembly steps, thereby maintaining simplicity while achieving stable fixation.
3Ease of manufacture
If the locking part is formed integrally with the bottom wall and outer edge, then manufacturing simplicity is improved, but the ease of assembly from flat storage position may be affected
Solution Approach 1:
The locking part with its projection is pre-formed on the base part during manufacturing. When the shell is erected from its flat storage position, the projection is already in place to automatically engage with the recess on the side wall. This preliminary preparation simplifies the assembly process, allowing the shell to be easily erected and secured in one continuous motion without requiring separate locking operations.
Solution Approach 2:
The integral locking part enables the base to self-service the assembly process. The projection automatically finds and engages with the recess on the side wall when the shell is erected, eliminating the need for separate locking steps or tools. This self-service mechanism maintains manufacturing simplicity while significantly improving assembly ease from the flat storage position.
