Hinged Closure System for Confined Space Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable cooler lids do not adequately address the challenges of limited access in confined spaces and the need for a stable surface for contents when opened, often requiring the cooler to be moved or damaging the surface beneath it, and none of the prior art solutions fully satisfy these requirements.
Innovation Solution
A hinged closure system for containers that includes a first and second closure with internal and external hinges, locking members, and pivot stops, allowing for a linear or nonlinear closure configuration to reduce height and create a horizontal table surface for access and support, while maintaining insulation and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional fixed lid is used on a portable cooler, then the cooler provides simple structural integrity and insulation, but it requires the entire cooler to be moved to access contents in confined spaces, which may damage the underlying surface
Solution Approach 1:
The lid is divided into multiple sections: a first closure section and a second closure section that can move independently relative to each other through a hinge mechanism. This segmentation allows the first section to be pivoted forward to create access channels without moving the entire cooler, eliminating surface damage while providing convenient access to contents.
2Ease of operation
If the cooler lid is opened in confined spaces, then access to contents is improved, but there is no stable surface to rest items removed from the cooler
Solution Approach 1:
The first closure section serves dual functions: it acts as a protective cover for the container contents when closed, and transforms into a stable table surface when pivoted forward. This multi-functionality provides a resting place for items removed from the cooler without requiring additional structures, enhancing versatility in confined spaces.
3Ease of operation
If a hinged lid system is implemented to improve access, then ease of operation is improved, but the device complexity increases with additional hinges and locking mechanisms
Solution Approach 1:
The hinge mechanism is designed to automatically lock and unlock based on the position of the first closure section. When the first section is pivoted forward to its limit, the hinge automatically engages to hold it in the open position without requiring separate locking actions. This self-service feature reduces operational complexity while maintaining ease of access.

AI summary
A hinged closure is disclosed for a container. The hinged closure comprises a first closure and a second closure. An internal closure hinge pivotably couples the first closure with the second closure. An exterior closure hinge pivotably couples the second closure with the container. A first locking member is couple to the interior edge of the first closure. A second locking member is coupled to the second closure. The first locking member engages with the second locking member for preventing pivoting of the first closure relative to the second closure and covering the container chamber and prevents access into the container chamber of the container. The first locking member disengaging with the second locking member for permitting pivoting of the first closure relative to the second closure and permitting access into the container chamber of the container and defines a reduced closure height relative to the container.
