Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding couches are packaged in large sizes, making transportation difficult and costly, necessitating a solution for easy folding and stowing to reduce package size.
Innovation Solution
A folding couch design featuring hinged bed frames, support assemblies with locking sliding sleeves, telescopic links, and adjustable backrests, allowing for compact storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the couch is designed to be foldable, then the package size is reduced and transportation is easier, but the structural complexity increases
Solution Approach 1:
The couch is divided into multiple bed frames (first bed frame, second bed frame) that can be independently folded and connected through hinges. Each bed frame can be separated into segments that fold independently, allowing the entire couch to be compacted into a smaller package size while maintaining manageable structural complexity through modular design
Solution Approach 2:
The support assemblies are designed to nest within the bed frames when folded. The support rods and locking sliding sleeves are configured to fit inside the bed frame structures, creating a compact nested configuration that minimizes package volume without requiring excessive structural elements
2Reliability
If support assemblies are added to maintain stability during folding, then the reliability improves, but the device complexity increases
Solution Approach 1:
The support assemblies incorporate movable support rods that can dynamically adjust their position and angle during the folding process. The rods are hinged to both bed frames and support frames, allowing them to move smoothly through different configurations while maintaining stability at each stage of folding and unfolding
Solution Approach 2:
The locking sliding sleeves are designed to automatically lock the support rods at appropriate positions during folding without requiring external assistance or complex control mechanisms. The sliding sleeves engage with the support rods through simple mechanical interference, providing self-stabilizing functionality that maintains reliability while minimizing added complexity
