Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spring bed is unfolded for use, then comfort is improved, but the occupied space increases making it difficult to store in a trunk
Solution Approach 1:
The spring bed is divided into multiple independent sections including a head section, body section, and foot section that can be separated. The cross bars are also segmented into front, rear, and central sections that can be detached from each other. This segmentation allows the spring bed to be disassembled into compact components for easy storage in a trunk while maintaining full functionality when assembled for use.
Solution Approach 2:
The spring bed incorporates rotatable connections between the central section and front/rear sections of the cross bars, allowing the structure to dynamically transition between extended (for use) and folded (for storage) configurations. This dynamic capability enables the spring bed to adapt its volume based on whether it is being used or stored.
2Volume of moving object
If the spring bed is collapsed for storage, then the occupied space is reduced, but the structure becomes unstable and uncomfortable
Solution Approach 1:
By segmenting the spring bed into modular sections with detachable connections, the structure can be confidently collapsed for storage without compromising stability during use. Each segment maintains its structural integrity independently, and the detachable connections ensure secure assembly when needed.
Solution Approach 2:
The spring bed employs conical springs instead of traditional spiral springs. The conical shape provides inherent structural stability while allowing compact nesting when collapsed. The conical geometry distributes loads more effectively and maintains structural integrity in both extended and collapsed states.
3Device complexity
If traditional spiral springs are used, then the structure is simple, but the springs occupy large space when packed
Solution Approach 1:
The patent replaces traditional spiral springs with conical springs. The conical shape allows the springs to nest within each other when not in use, dramatically reducing the storage volume required. The conical geometry maintains structural functionality while enabling compact packaging.
Solution Approach 2:
The conical springs are designed to nest within each other when collapsed, similar to nested dolls. This nesting capability allows multiple springs to occupy the space of a single spring, significantly reducing the overall package size of the spring bed when stored.
4Reliability
If the spring bed is designed for durability, then the structure becomes rigid and difficult to assemble/disassemble
Solution Approach 1:
The spring bed is divided into modular sections with standardized detachable connections. This segmentation allows for easy assembly and disassembly while maintaining durability through robust connection points designed to withstand repeated assembly cycles.
Solution Approach 2:
The rotatable connections between cross bar sections provide a dynamic assembly mechanism that is both durable and easy to operate. The rotatable joints are designed to be simple to manipulate while maintaining strong structural connections during use.
