Coffee Capsule Storage Rack with Dual-Caster Mobility Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coffee capsule storage racks are inconvenient to move, especially when loaded with a large number of capsules, as they require manual lifting and dragging, and the design restricts the full opening of coffee machine lids due to height limitations, leading to poor user experience.
Innovation Solution
A movable coffee capsule storage rack with a dual-caster system and a handle mechanism that allows easy switching between fixed and moving states, enabling the rack to be slid with minimal user effort, even when a coffee machine is stacked on it, by using a second caster to support the rack body and facilitate simultaneous movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the storage rack uses a fixed support leg structure, then it provides stable support and prevents sliding, but it becomes difficult to move when loaded with heavy coffee capsules
Solution Approach 1:
The support leg is designed to be rotatable rather than fixed, allowing it to dynamically switch between a horizontal stable support position and a vertical moved position. This enables the rack to transition from a stable fixed state to an easily movable state by simply rotating the support leg 90 degrees, resolving the contradiction between stability and ease of movement.
2Ease of operation
If the storage rack is designed to be movable with casters, then it is easy to move, but it cannot remain stable when placed on a surface
Solution Approach 1:
The rack alternates between two stable states: when the support leg is horizontal, the rack is stable on the surface; when the support leg is rotated to vertical, the casters engage with the surface to provide stability during movement. This dynamic switching allows the rack to achieve both stability and ease of movement at different operational phases.
3Strength
If the support leg is fixed to the rack body, then the structure is simple and strong, but it requires significant force to move the rack when loaded
Solution Approach 1:
The support leg is connected to the rack body through a rotating joint rather than a fixed connection. This maintains structural strength through the joint while enabling the leg to be easily rotated between horizontal and vertical positions. The rotation mechanism preserves structural integrity while dramatically reducing the force needed to initiate movement.
4Ease of operation
If the rack uses only casters for movement, then it can move freely, but it cannot be securely positioned on a surface
Solution Approach 1:
The support leg acts as a positioning mechanism that, when rotated to the horizontal position, provides a fixed reference point that secures the rack's position on the surface. When rotated to vertical, it allows the casters to bear the full weight and enable movement. This dynamic positioning system resolves the contradiction between mobility and position stability.
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 solution allows for convenient and effortless movement of the storage rack and coffee machine as a whole, reducing user burden and enabling easier access to coffee capsules and the coffee machine, while maintaining stability in both states.
Implementation Method 1
through the friction between the support leg 8 and a desktop, the storage rack 2 can be placed on a decorative cabinet, a bar counter, the desktop or other bearing platforms stably without a large external force

AI summary
A movable coffee capsule storage rack includes a rack body for storage of coffee capsules. A first bracket is fixed to the bottom of the rack body, a first caster is rotatably connected to the first bracket through a first rotating shaft, a second bracket is disposed adjacent to the support leg, a second caster is connected to a second end of the second bracket, and when the second bracket is driven to rotate by the handle to drive the second caster to move down to hold up the support leg, the rack body is entirely supported by the first caster and the second caster and realizes free sliding. With the structure of the present disclosure, the storage rack is allowed to be switched quickly between the fixed state and the moving state through the movement of the second caster, the structure is simple, and the operation is convenient.
