Portable Beverage Chest Recess Strap Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable beverage chests face challenges in securing them to objects during transport, as current strap attachment methods are time-consuming and obstruct access to the contents, discouraging multiple users due to the need for frequent strap repositioning and custom fabrication.
Innovation Solution
A portable beverage chest design featuring a recess adjacent the cover, allowing for secure attachment using a cargo strap without obstructing lid mobility or access, and incorporating a collar with a recess and channel for strap retention, along with handles and a drain for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a strap is placed over the top of the cooler or through slits under the lid to secure it, then the cooler can be attached to an object for transport, but the lid becomes immobile and access to contents is blocked
Solution Approach 1:
The securing function is segmented from the lid structure. The strap attaches to the body of the cooler through dedicated attachment points on the sidewalls, separate from the lid, allowing the lid to remain movable and accessible while the cooler itself is secured to the transport object.
Solution Approach 2:
The strap attachment mechanism is extracted from the lid area and relocated to the sidewall area of the cooler body. This extraction allows the strap to secure the cooler without interfering with lid mobility or access to the contents stored inside.
2Stability of the object's composition
If custom-fabricated metal latches are used to form slits and provide strap attachment, then secure attachment is achieved, but manufacturing cost increases
Solution Approach 1:
The cooler body structure itself serves multiple functions: it provides the cooling enclosure, structural support, and strap attachment points. The sidewalls are designed with integrated attachment points that work with standard straps, eliminating the need for custom-fabricated metal latches and reducing manufacturing complexity and cost.
Solution Approach 2:
The cooler's own structural components (sidewalls) provide the attachment function without requiring separate custom-fabricated parts. The design allows the cooler to secure itself to transport objects using standard straps, making the system self-sufficient and cost-effective.
3Ease of operation
If straps are repositioned to allow lid mobility and access, then accessibility is improved, but the securing function is compromised and time is lost
Solution Approach 1:
The securing function is segmented from the lid structure. The strap attaches to the body of the cooler through dedicated attachment points on the sidewalls, separate from the lid, allowing the lid to remain movable and accessible while the cooler itself is secured to the transport object.
Solution Approach 2:
The attachment points are pre-positioned on the sidewalls during manufacturing, allowing the strap to be quickly attached without requiring field modifications or repositioning. Users can simply attach the strap to the pre-positioned points and begin using the cooler immediately.

AI summary
A portable beverage chest comprises a floor having one or more upstanding sidewalls depending from the floor. The floor and sidewalls defining a storage area between the floor and sidewalls. The exterior surface of one or more of the upstanding sidewalls mutually join the collar and form a recess. The recess may be used to apply a strap, cord, or bungee thereabouts to secure the chest to an object without obstructing the cover and access to the contents protected by the cover.
