Adjustable-Collapsible Packaging Assembly with Resilient Lid Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container-lid combinations fail to effectively adjust volumetric space and secure the lid to the container, leading to issues with liquid leakage and inadvertent lid removal.
Innovation Solution
A packaging assembly with a dynamic lid and static container, featuring a rim-receiving groove and resilient portion that can transition between unlocked and locked configurations, allowing for adjustable volume and enhanced lid retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static container-lid combination is used, then manufacturing is simple and cost-effective, but the volumetric space cannot be adjusted and lid retention is weak
Solution Approach 1:
The lid is designed with resilient portions that can transition between unlocked and locked configurations, enabling dynamic adjustment of the packaging volume. The resilient portions flex to allow volume adjustment and then lock to maintain the selected configuration, providing adaptability without requiring complex mechanical systems.
Solution Approach 2:
The lid structure is segmented into multiple resilient portions that can independently engage with corresponding features on the container. This segmentation allows selective locking at different positions, enabling adjustable volumetric space while maintaining structural integrity and simplicity.
2Reliability
If a simple rim-receiving groove is used, then manufacturing is easy, but the lid can be inadvertently removed and liquid leakage occurs
Solution Approach 1:
The attachment mechanism uses resilient portions that dynamically transition between engaged and disengaged states. When the lid is properly installed, the resilient portions flex and lock into place, providing secure retention. The mechanism requires deliberate action to release, preventing inadvertent removal while maintaining manufacturing simplicity.
Solution Approach 2:
The resilient portions change their physical state from flexible during installation to locked during retention. This parameter change allows the same structure to provide both easy installation and secure retention, eliminating the need for complex separate locking mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables users to selectively adjust internal volume and securely retain the lid, reducing liquid leakage and inadvertent removal, while also being stackable and cost-effective.
Implementation Method 1
at least one resilient portion extending between the body wall and the rim-receiving groove and resiliently actuable between (a) an unlocked configuration and (b) a locked configuration

AI summary
A package assembly enables a user to adjust package assembly volume and includes a first (static or dynamic) package body and a second dynamic package body. The first package body has an upper body rim. Each dynamic package body provides a dynamic lid volume and has a rim-receiving groove, a lid wall, and at least one resilient portion. The rim-receiving groove is removably attachable to the upper body rim for defining a dynamic package assembly volume with the package body when in a closed configuration with the first package body. The resilient portion extends intermediate the lid wall and the rim-receiving groove and is resiliently actuable intermediate (a) a relaxed configuration for defining a maximum package assembly volume when in the closed configuration and (b) an actuated configuration defining a minimum package assembly volume in the closed configuration.
