Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional paper-made gifts are prone to damage during assembly due to interlocking slits, making them weak and difficult to assemble, especially for those less skilled in handicrafts, and disassembly is inconvenient, leading to a lack of interest in DIY assembly.
Innovation Solution
A creative assembly model structure featuring symmetrical modeling bodies with protruding parts and insertion slots, folding lines, and fitting protrusions and notches that facilitate easy assembly by folding and fixing, along with additional modeling parts for enhanced aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If interlocking slits are used to assemble paper-made gifts, then the structure can be assembled together, but the interlocking slits are easily damaged during assembly resulting in weak structure and difficulty for less skilled individuals
Solution Approach 1:
The patent divides the modeling body into multiple segments with protruding parts and corresponding insertion slots. Each segment can be independently assembled, reducing the complexity of the overall assembly process and making it more accessible to less skilled individuals while maintaining structural integrity through multiple connection points
Solution Approach 2:
The patent introduces fitting parts as intermediary elements between the protruding parts and insertion slots. These fitting parts act as mediators that facilitate the connection process, guiding the assembly together while distributing mechanical stress to prevent damage to the interlocking structures
2Strength
If interlocking slits are made longer or deeper for firmness, then the finished product becomes firmer, but it becomes easier to damage the parts during assembly and disassembly becomes inconvenient
Solution Approach 1:
The patent designs the connection structure with flexible fitting parts that can dynamically adjust during assembly and disassembly. The fitting parts allow the connection to be firm when assembled but easily separated when needed, providing both strength and ease of operation through dynamic mechanical behavior
Solution Approach 2:
The patent incorporates preliminary guiding features in the fitting parts and insertion slots that prepare the components for easy assembly. The guiding features align the parts correctly before final connection, reducing the force needed during assembly and making disassembly equally easy by reversing the alignment process
3Productivity
If traditional interlocking slits are used, then assembly can be completed, but less skilled individuals lack interest due to difficulty in assembly
Solution Approach 1:
The patent designs the assembly structure to be self-aligning and self-assembling. The protruding parts and insertion slots are configured to automatically guide each other into the correct position, and the fitting parts automatically engage when the components are brought together, eliminating the need for skilled manual manipulation and making DIY assembly accessible to everyone
