Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for fixing straight bars and cross bars of pet guardrails are time-consuming due to the use of bolts, which hinder efficient assembly.
Innovation Solution
A fixing structure that utilizes a power punch bar to deform the bar wall and form a locking pellet, which is embedded into a fixing hole to securely connect the straight bars and cross bars without the need for bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bolts are used for fixing the straight bars and cross bars, then the connection strength is ensured, but the assembly time increases significantly
Solution Approach 1:
The invention extracts and eliminates the bolt from the fixing system, replacing it with a direct mechanical interlocking structure where the cross bar is inserted into the fixing hole of the straight bar, achieving connection without fasteners
Solution Approach 2:
The cross bar structure itself serves as the fixing mechanism through its geometric shape and insertion fit, making the connection self-sufficient without requiring external fastening components like bolts
2Productivity
If a complex fixing mechanism is designed to reduce assembly time, then the productivity increases, but the device complexity increases
Solution Approach 1:
The fixing structure is segmented into simple modular components: the fixing hole in the straight bar and the corresponding insertion structure in the cross bar, allowing for easy assembly and disassembly without complex mechanisms
Solution Approach 2:
Instead of using active fastening elements (bolts that need to be tightened), the invention uses a passive interference fit where the cross bar geometry itself provides the fixing function through its insertion into the hole, inverting the traditional fastening approach

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables rapid and stable fixation of straight bars and cross bars, reducing assembly time and ensuring a secure, bolt-free connection.
Implementation Method 1
the bar wall of the cross bar corresponding to the fixing hole is applied force and punched by a power punch bar so that a locking pellet is formed on the deforming wall
Implementation Method 2
the bar wall of the cross bar corresponding to the fixing hole is applied force and punched by a power punch bar

AI summary
The present invention is to provide a fixing structure of a straight bar and a cross bar of a pet guardrail, mainly, a fixing hole is respectively configured on a top end and a bottom end of the straight bar, the top end and bottom end of the straight bar are respectively embedded into an embedding slot configured on the cross bar, then a punch head of a power punch bar is reaching into from an opening slot configured on one side of the cross bar to apply a force and punch the sharing slot wall between the embedding slot and the opening slot and corresponding to the fixing hole, thereby enabling a punched position of the sharing slot wall to be deformed and protrude toward the fixing hole to form a locking pellet, so the locking pellet is embedded into the fixing holes to combine the straight bara and the cross bars, thereby enabling the combination and fixation between the straight bar and the cross bar of the pet guardrail to be effective.
