Cap unit with handle and capped container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cap units with rotatable handles are prone to damage from impacts due to the stress applied to the hinge and handle components, leading to potential breakage or deformation, which compromises the usability and durability of capped containers.
Innovation Solution
A cap unit design featuring a handle member with an arch-shaped curve that decreases in thickness towards the middle, equipped with a detachment prevention mechanism and a clicking mechanism to absorb impact and prevent elastic deformation, ensuring the handle and hinge remain secure and functional.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle is rotatably attached to the cap body via hinge parts, then portability is improved, but the handle and hinge may be damaged by impact loads
Solution Approach 1:
The patent applies beforehand cushioning by designing the hinge part with a detachable structure that can separate under excessive impact loads. The cap body and handle member are connected through hinge parts that include engagement protrusions and engagement recesses, which can detach when subjected to impact forces beyond a certain threshold, thereby protecting the main structure from damage while maintaining portability during normal use
2Stability of the object's composition
If the handle is made with an arch shape, then flexibility is improved, but the rivet-like parts may come off and the handle may separate from the hinge
Solution Approach 1:
The patent applies segmentation by dividing the handle structure into modular components with distinct engagement features. The handle member includes engagement protrusions that fit into engagement recesses in the cap body, creating segmented but securely connected parts. This allows the handle to maintain its arch shape flexibility while preventing separation through the interlocking engagement features
3Ease of operation
If the handle is designed to be rotatable, then usability is improved, but the hinge part is vulnerable to elastic deformation under impact
Solution Approach 1:
The patent applies dynamics by designing the hinge part with controlled detachable characteristics that allow rotational movement during normal use but provide protective separation under excessive loads. The engagement protrusions and recesses are designed to maintain connection during rotation while allowing detachment when impact forces cause elastic deformation beyond safe limits, thus preserving both usability and strength
Applied Scientific Principles
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 cap unit effectively prevents damage to the handle and hinge components during impacts, enhancing the usability and durability of capped containers by allowing the handle to rotate securely and absorb shock through elastic deformation, maintaining its structural integrity.
Implementation Method 1
the handle member has an arch part that curves between the two ends and has a shape that decreases in thickness from the two ends toward the middle of the arch part

AI summary
To provide a cap unit that prevents damage to the handle or hinge part when an impact or the like is applied to a handle or hinge part, a cap unit 1A is detachably attached to a container body 2 with an opening in the upper part thereof, provided with a cap body 7 for closing an upper opening of the container body 2 and a handle member 9 having both ends rotatably attached via a pair of hinge parts 8 to the cap body 7, wherein the handle member 9 has an arch part 9a that curves between both ends and has a shape that decreases in thickness toward a middle part of the arch part 9a, and is rotated between a first position positioned above the cap body 7 and a second position positioned on the side of the cap body 7.
