Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container lids with through-holes for straws are inconvenient, difficult to manufacture, and costly, and existing reclosable designs are cumbersome and require additional plastic, making them less environmentally friendly.
Innovation Solution
A strawless drinking lid with a recessed drinking portion that can be moved between closed and open configurations using external forces, featuring a single-piece thermoformed polymer design with a hinge mechanism for easy operation and reduced material use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional lids with pre-stamped through-holes are used, then sipping function is provided, but manufacturing complexity increases due to slug removal and collection steps
Solution Approach 1:
The patent removes the through-hole completely from the lid structure, extracting the sipping function to a separate reusable straw. This eliminates the need for slug removal and collection steps in manufacturing, simplifying the production process while maintaining the sipping capability through an alternative mechanism.
Solution Approach 2:
The invention separates the lid and straw into distinct components, with the lid providing a sealed closure and the straw providing the sipping function. This segmentation allows the lid to be manufactured without any holes or openings, eliminating complex manufacturing steps while the straw can be easily attached or removed by the user.
2Ease of operation
If lids with open sip holes are manufactured, then sipping function is available, but portability and security are reduced
Solution Approach 1:
The patent employs a dynamic reclosable opening mechanism that allows the lid to transition between sealed and open states. This dynamic feature provides security during transport when closed, while allowing easy access when opened, enhancing both portability and security without requiring permanent openings in the lid structure.
3Ease of operation
If reclosable designs with flaps or plugs are used, then reclosability is achieved, but operation difficulty and dexterity requirements increase
Solution Approach 1:
The patent uses a simple pull-tab or break-seal mechanism that requires minimal user action to open and close. Rather than complex flap or plug mechanisms requiring precise dexterity, the design allows users to easily reclose the container with a simple motion, reducing operational complexity while maintaining effective reclosability.
4Ease of operation
If tethered or attached plug designs are used, then reclosability is provided, but manufacturing costs and material usage increase
Solution Approach 1:
The patent employs a simple reclosable mechanism using minimal additional material, such as a thin break-seal layer or simple tab structure. This approach provides reclosability functionality while using significantly less plastic compared to tethered plugs or attached accessories, reducing both material consumption and manufacturing costs.

Function Achieved in This Case
Provides a convenient, easy-to-use, and eco-friendly lid solution that minimizes manufacturing complexity and costs while ensuring portability and ease of use.
Implementation Method 1
The recessed drinking portion can be configured to be moved from the closed configuration toward the open configuration by an external opening force applied on the front section of the upper surface to deform the front section relative to the center portion
Implementation Method 2
The front section can be configured to conform to the hinge in the open configuration, and the front section can invert upwardly as the front section conforms to the hinge
Implementation Method 3
The back section of the upper surface can be deformed past a point of maximum opening stress
Implementation Method 4
The front section of the upper surface can be deformed past a point of maximum closing stress

AI summary
Strawless drinking lid for a container, having a mounting portion defining an outer perimeter and a perimeter wall disposed inwardly from the mounting portion. The perimeter wall extends upwardly relative the mounting portion and has an outer surface facing the mounting portion and an inner surface opposite the outer surface. The strawless drinking lid further has a center portion extending inwardly from the inner surface of the perimeter wall and a recessed drinking portion extending from the center portion. The recessed drinking portion includes an upper surface having a front section and a back section with a hinge therebetween. The front section has a front edge proximate a ledge extending from the inner surface of the perimeter wall. The recessed drinking portion has a closed configuration and an open configuration.
