Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for connecting guardrails or fencing to concrete structures face challenges in simplicity, cost-effectiveness, and structural integrity, often requiring complex welding and risking concrete damage with existing anchor systems.
Innovation Solution
An adjustable post-to-substrate embed system featuring a plate with anchor holes, adjustable nuts and anchors, and a bracket for aligning with concrete containment forms, allowing for flexible depth adjustment and secure anchoring without welding, using off-the-shelf fasteners and minimizing concrete damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional welding methods are used to connect guardrails to concrete structures, then structural strength is improved, but manufacturing complexity and cost increase due to requiring clean surfaces and welding equipment
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with a purely mechanical fastening system using bolts, nuts, and washers. The mounting plate incorporates pre-drilled holes that align with concrete anchor points, allowing assembly through simple bolting operations without requiring welding equipment, surface cleaning, or specialized welding skills.
Solution Approach 2:
The mounting plate is pre-manufactured with precisely drilled and tapped holes for bolt insertion. This preliminary preparation eliminates the need for on-site hole drilling, threading, or surface preparation that would otherwise be required during installation, significantly simplifying the manufacturing and installation process.
2Strength
If expansion anchors are used to secure posts to concrete, then anchoring strength is improved, but the risk of concrete damage and structural failure increases
Solution Approach 1:
The patent uses simple, replaceable fastening components (bolts, nuts, washers) that can be installed and removed without damaging the concrete substrate. These conventional fasteners are preferred over expensive, permanent expansion anchors that risk concrete failure. The mounting plate itself can be removed and reused if needed, providing flexibility without concrete damage.
3Shape
If mounting plates are embedded flush with concrete surface, then aesthetic appearance is improved, but accessibility for welding and maintenance becomes difficult
Solution Approach 1:
The mounting plate is designed with a removable mounting plate component that can be taken off the concrete substrate. This dynamic design allows the plate to be removed for easy access to the fastening points underneath, facilitating maintenance, adjustments, or repairs without concrete damage. The plate can then be reinstalled to restore the flush appearance when not in use.
4Reliability
If complex anchor systems are used to ensure structural integrity, then reliability is improved, but device complexity and installation time increase
Solution Approach 1:
The mounting plate serves multiple functions simultaneously: it provides a mounting surface for the guardrail, incorporates alignment features for precise positioning, includes pre-drilled holes for secure fastening, and offers a removable design for maintenance access. This multi-functional design eliminates the need for separate alignment tools, mounting brackets, and fastening mechanisms, reducing overall system complexity while maintaining reliability.
