Innovation Solution
A storage device with a regulating assembly that includes a first and second partition frame, connected through a cam structure allowing for adjustable division of the cavity, enabling the device to switch between folded and unfolded states for varying storage needs, with elastic driving forces ensuring easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a partition frame is used to divide the accommodation cavity, then the storage organization is improved, but the device complexity and difficulty of assembly/disassembly increases
Solution Approach 1:
The partition frame is divided into multiple independent partition boards that can be separately installed and adjusted. Each partition board can be independently positioned to create flexible storage compartments, allowing users to organize food items according to their specific needs without dealing with a complex integrated structure.
Solution Approach 2:
The partition boards are designed to be movable and adjustable along the side walls of the storage device. This dynamic configuration allows the partition spacing to be changed according to different storage requirements, transforming a static partition structure into a flexible, adaptable system that can be easily reconfigured.
2Adaptability or versatility
If partition frames are used to divide the accommodation cavity, then storage division is achieved, but the ease of operation deteriorates due to fixed partition spaces
Solution Approach 1:
The partition boards are designed with movable features that allow them to be easily repositioned along the side walls. Users can adjust the position of each partition board independently to create custom compartment sizes, transforming fixed partition spaces into dynamic, adjustable configurations that adapt to different storage needs.
Solution Approach 2:
The partition spacing and compartment dimensions can be changed by adjusting the position of partition boards. This parameter adjustment capability allows users to optimize the storage configuration for different types and quantities of food items, improving operational flexibility without requiring a complete restructuring of the partition system.
3Stability of the object's composition
If a complicated assembly structure is used for partition frames, then structural stability is improved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The partition frame structure is segmented into independent partition boards that can be manufactured separately using simple processes. Each partition board is a discrete component that can be easily produced and then assembled into the final configuration, reducing manufacturing complexity while maintaining structural integrity through proper connection design.
Solution Approach 2:
The partition boards are designed with self-aligning or self-locking features that facilitate easy assembly without requiring complex tools or procedures. The simple modular design allows users to assemble and disassemble the partition structure themselves, reducing the need for specialized assembly processes while ensuring stable construction.
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 enhances flexibility in dividing the accommodation cavity, improves ease of assembly and disassembly, and prevents food items from sliding and becoming disorganized, thus making food storage more efficient and convenient.
Implementation Method 1
a cam structure, comprising a first concave-convex curved surface formed on the first regulating mechanism and a second concave-convex curved surface formed on the second regulating mechanism; when the first and second regulating mechanisms are rotated around the vertical axis with respect to each other, the second and first concave-convex curved surfaces are butted against each other, such that the first and second regulating mechanisms make reciprocating salutatory movements away from or close to each other in the vertical direction
Implementation Method 2
when the first and second regulating mechanisms are rotated with respect to each other around the vertical axis and the cam structures are not at the lowest engaging position, the regulating assembly is always subjected to an elastic driving force which drives the cam structures to tend to move to the lowest engaging position
