Fence Panel Rod-Locking Structure for Stable Bar Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fence systems, particularly for long panels, suffer from vertical bars that can move or deform over time, leading to instability and potential safety hazards, and lack modularity and ease of assembly.
Innovation Solution
A fence grid design featuring a rail with through holes for bars, secured by rods passing through subsets of bars and fixed by assembly accessories, with insulating foam filling gaps to enhance stability and soundproofing, and modular design allowing easy customization and length adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rod or cable is used to lock vertical bars into a horizontal rail, then the assembly is simple, but the bars can move slightly or deform over time, reducing stability
Solution Approach 1:
The single rod or cable locking mechanism is segmented into multiple rods, with each rod passing through a subset of bars rather than all bars. This segmentation allows for more precise localization and locking of bar positions, preventing movement and deformation while maintaining assembly simplicity through modular installation
Solution Approach 2:
An assembly accessory is introduced as an intermediary component to facilitate the connection between rods and bars. The assembly accessory includes positioning elements that guide rod insertion and ensure proper alignment, making the multi-rod system as easy to assemble as a single rod system while significantly improving bar stability
2Reliability
If a rod passes through all bars to lock them in place, then bar immobilization is maximized, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The locking mechanism is divided into multiple independent rods, each responsible for a subset of bars. This allows bars to be locked in groups rather than requiring all bars to be processed simultaneously, significantly reducing assembly time while maintaining complete immobilization of all bars through the combined action of multiple rods
Solution Approach 2:
The assembly accessory incorporates pre-positioned guide elements and positioning features that prepare the assembly path for rods before insertion. This preliminary positioning ensures rapid and accurate rod insertion without requiring complex alignment procedures, thereby increasing assembly speed while ensuring reliable bar immobilization
3Ease of manufacture
If bars pass through the rail, then assembly is straightforward, but safety hazards and injury risks increase
Solution Approach 1:
The dangerous protruding ends of bars that pass through the rail are extracted or removed by modifying the bar-rail interaction. Instead of bars passing completely through the rail with exposed ends, the bar mounting portions are housed within the rail cavity and secured by rods, eliminating the safety hazard while maintaining assembly simplicity through the same basic insertion process
Solution Approach 2:
The rod-assembly accessory system serves as an intermediary mechanism that secures bars within the rail without requiring bars to protrude through it. The assembly accessory provides internal locking features that hold bars in place from within the rail structure, eliminating exposure hazards while maintaining ease of assembly through standardized insertion and locking procedures
Applied Scientific Principles
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 provides enhanced structural stability, soundproofing, and safety by preventing bar movement, while allowing for easy assembly and customization, including color variation and length adjustment.
Implementation Method 1
the cavity being filled with insulating foam extending between the bars
Implementation Method 2
this helps to avoid sound vibrations due to the movement of the bars in the rail under the effect of the wind, for example
Implementation Method 3
two rods and an assembly accessory, each rod passing through a subset of said bars through the through holes and being fixed at a first end of said assembly accessory
