Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a cylindrical block and hole structure is used for rotational connection, then the structural strength is improved, but the assembly force required increases and user experience deteriorates
Solution Approach 1:
The connection structure is divided into two functional parts: a cylindrical block for rotational connection and a C-shaped elastic ring for fastening. This segmentation allows each component to specialize in its function, reducing the force needed for assembly while maintaining structural strength.
Solution Approach 2:
The C-shaped ring utilizes elastic deformation parameters to enable easy assembly. By changing the physical state from rigid to elastic, the connection can be formed with small force, and the elastic recovery provides secure fastening without requiring excessive assembly force.
2Ease of operation
If a sheet-shaped structure or C-shaped ring is added for elastic deformation, then the assembly force is reduced, but the structural strength during flipping deteriorates
Solution Approach 1:
The invention merges the cylindrical block (for rotation) with the C-shaped elastic ring (for fastening) into an integrated connection assembly. This combination allows the structure to benefit from both the low assembly force of elastic deformation and the high structural strength of the rigid block-hole connection during flipping operations.
3Stability of the object's composition
If the trash can is transported in a well-assembled form, then the structural integrity is maintained, but the transportation cost increases due to excessive size
Solution Approach 1:
The connection structure transitions from a static rigid connection to a dynamic assembly that can be easily formed and disassembled. The elastic C-shaped ring allows the lid to be quickly attached or detached without compromising structural integrity, enabling flexible transportation arrangements that reduce space and cost.
4Productivity
If multiple lids are placed inside the top trash container for stacking, then the stacking efficiency is improved, but the risk of lost lids or misplacement increases
Solution Approach 1:
The C-shaped elastic ring provides self-retaining functionality through elastic deformation. When the lid is placed on the container, the ring automatically deforms and snaps into place, securing the lid without requiring additional fastening actions. This self-service mechanism ensures lids remain attached during stacking and transportation.
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 enables efficient transportation and stacking of trash cans, simplifies the assembly process for users, reduces the risk of lost lids, and enhances user experience while maintaining structural integrity.
Implementation Method 1
a thinner sheet-shaped structure or C-shaped ring which can subject to elastic deformation is additionally arranged, on which the block or hole is arranged. Optionally, the C-shaped ring is used as a clamping fastener, such that the sheet-shaped structure or the C-shaped ring can be elastically deformed under the action of a small force to form the rotational snap fit.

AI summary
A fixing structure for lid assembly and disassembly of a trash can, including a hanging structure. The trash can includes a trash can body, a lid and a connecting part. The hanging structure includes a groove and a hanging part. The groove is provided on an outer side wall of the trash can body. The hanging part is provided on the lid. The hanging part and the groove are configured to be engaged with or disengaged from each other to enable the attachment of the lid to the trash can body or the detachment of the lid from the trash can body. When the connecting part is disengaged from the lid, the lid is hung on a side of the trash can body.
