Pet Cage Folding Support-Rod Structure for Error-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet cages face installation errors due to different structures of upper support rods, making assembly inconvenient and replacement of damaged parts difficult.
Innovation Solution
The pet cage features two first connecting pipes with identical structures, each equipped with hinge joints and a sleeve for easy unfolding and folding, and includes elastic limit buckles and limit members to secure the sleeve position, along with connectors for stable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the two opposite upper support rods are connected together through insertion with different specific structures, then the cage structure can be formed, but installation becomes error-prone and inconvenient
Solution Approach 1:
The patent applies asymmetry in reverse by making both upper support rods symmetric (identical in structure). This resolves the installation confusion caused by asymmetric designs, allowing users to connect any rod to any slot without distinguishing between left and right rods, thereby improving installation convenience.
Solution Approach 2:
Both upper support rods are designed with identical structures, making them universal and interchangeable. Each rod can be inserted into either slot, and each slot can receive either rod, eliminating the need for specific differentiation and simplifying the installation process.
2Ease of repair
If the two opposite upper support rods have different specific structures, then the cage structure can be formed, but replacement of damaged parts becomes inconvenient
Solution Approach 1:
The patent eliminates structural differentiation between the two upper support rods, making them identical. This ensures that if one rod is damaged, the user can replace it with the other identical rod without needing to match specific structural features, greatly simplifying the repair process.
Solution Approach 2:
Both upper support rods are designed as universal, interchangeable components with identical structures. This universality allows either rod to replace the other, making part replacement convenient and eliminating the complexity of matching specific structural variants.
3Ease of operation
If the sleeve is freely movable on the support rod, then assembly and disassembly is simple, but the position of the sleeve cannot be secured
Solution Approach 1:
The sleeve is designed with dynamic characteristics, allowing it to slide freely along the support rod for easy assembly and disassembly. The elastic limit buckle provides a stopping point that can be overcome by applying force, enabling the sleeve to move dynamically while maintaining position stability when secured.
Solution Approach 2:
The elastic limit buckle acts as a pre-positioned mechanical stop that cushions the sleeve's movement. When the sleeve reaches the buckle, the elastic deformation provides a stopping force that secures the sleeve at the desired position, preventing unintended movement while maintaining ease of assembly.
