Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional collapsible frames are used to protect sheet-like materials, then some protection is provided, but the sheets are still vulnerable to diagonal and transverse forces causing rips, and lack front and back protection
Solution Approach 1:
The frame is divided into multiple independent elongate members (first pair and second pair) that can be separately assembled. Each member provides protection to specific portions of the sheet, with the first pair protecting top and bottom edges and the second pair protecting side edges, creating comprehensive protection through modular segmentation.
Solution Approach 2:
The patent combines multiple protective functions into a single integrated frame structure. The first and second pairs of elongate members are joined at corners to form a unified frame that simultaneously provides protection against diagonal forces, transverse forces, and edge damage, merging what would otherwise require separate protective devices.
2Object-affected harmful factors
If frames with multiple pieces are used to provide comprehensive protection, then protection is improved, but the frames become expensive and difficult to manufacture and procure
Solution Approach 1:
The frame consists of only four basic elongate members divided into two simple pairs, minimizing the number of components while achieving comprehensive protection. This segmented approach with minimal parts reduces manufacturing complexity, assembly steps, and procurement costs compared to frames requiring eight or more pieces.
Solution Approach 2:
Each elongate member is designed to serve multiple functions: providing structural support, protecting sheet edges, and enabling collapsible assembly. The first pair of members protects top and bottom edges while the second pair protects side edges, with all members working together to resist various forces, reducing the need for specialized components.
3Object-affected harmful factors
If frames with many pieces are used to provide comprehensive protection, then protection is improved, but the frames require many pieces that may easily be lost and are difficult to package or ship
Solution Approach 1:
The frame is segmented into only four essential members organized in two pairs, minimizing the number of discrete components that could be lost. This segmentation into a minimal set of critical parts simplifies inventory management, assembly, and storage compared to frames with eight or more pieces.
Solution Approach 2:
The frame members are designed to nest within each other when collapsed, with the first and second pairs of elongate members fitting together in a compact configuration. This nesting capability allows the entire frame to be stored or shipped in a small space, eliminating the need for separate packaging materials and reducing the risk of pieces being lost during transport.
4Ease of manufacture
If simple frames are used to reduce manufacturing complexity, then ease of manufacture is improved, but protection on all sides including front and back is not achieved
Solution Approach 1:
The protective function is segmented across four different elongate members positioned at the corners and edges of the sheet. Each member protects a specific portion of the sheet perimeter, and together they provide comprehensive protection on all sides including front and back, achieving complete coverage through functional segmentation rather than a single complex component.
Solution Approach 2:
The patent merges the protective capabilities of multiple members into a single frame structure that simultaneously protects all sides of the sheet. The first pair of members protects top and bottom edges while the second pair protects side edges, combining these functions into one integrated system that provides comprehensive protection without requiring multiple separate devices.
5Object-affected harmful factors
If frames requiring many assembly steps are used to provide comprehensive protection, then protection is improved, but the frames require a plethora of steps to configure
Solution Approach 1:
The frame is pre-segmented into two pairs of elongate members with attachment features already positioned for optimal assembly. The first pair connects to the second pair at predetermined corner locations, allowing rapid configuration through simple connection steps rather than complex multi-stage assembly procedures.
Solution Approach 2:
The elongate members are pre-configured with attachment features (such as slots, tabs, or connection points) during manufacturing, so that assembly requires only simple connection actions rather than multiple configuration steps. This preliminary preparation of attachment mechanisms significantly reduces the time and complexity required to assemble the complete frame structure.
6Ease of operation
If frames that damage the sheet are used to achieve assembly, then assembly is simplified, but the sheet cannot be used a second time and loses value
Solution Approach 1:
The attachment mechanism is segmented into non-invasive components that connect frame members to each other and to the sheet without requiring holes or permanent modifications. The elongate members use external attachment features that preserve the integrity of the sheet, allowing repeated assembly and disassembly while maintaining sheet value and reusability.
