Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guardrail systems and solar panel array foundations face challenges in cost-effectiveness, efficiency, and labor-intensive installation processes, particularly due to the use of steel and concrete materials, which also raise concerns about material costs, durability, and environmental exposure.
Innovation Solution
A one-piece plastic foundation or support post system, made from fiber-reinforced resin, featuring a Z-shaped design with angled flanges and an integral offset block spacing plate, which is manufactured via pultrusion or pulforming processes, allowing for easy installation and reduced labor costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel support posts and concrete foundations are used, then structural strength and durability are improved, but material cost and installation complexity increase
Solution Approach 1:
The patent combines the foundation and support post into a single integrated one-piece plastic structure. The Z-shaped design integrates the foundation base and vertical support post as one continuous fiber-reinforced plastic component, eliminating the need for separate concrete foundations and steel posts, thereby reducing installation complexity while maintaining structural strength
Solution Approach 2:
The patent uses fiber-reinforced plastic (composite material) to replace traditional steel and concrete materials. The fiber reinforcement provides structural strength comparable to steel, while the plastic matrix offers corrosion resistance and simplifies installation, resolving the contradiction between strength and installation complexity
2Reliability
If steel support posts are used, then durability is improved, but material cost and maintenance requirements increase
Solution Approach 1:
The fiber-reinforced plastic material provides durability comparable to steel through fiber reinforcement, while the plastic component eliminates rust and corrosion issues. This composite approach maintains reliability while reducing material cost and maintenance requirements associated with traditional steel posts
Solution Approach 2:
The patent changes the material parameter from metal to fiber-reinforced plastic, fundamentally altering the properties of the support structure. This material substitution provides equivalent or superior durability without the cost and maintenance burden of steel, resolving the contradiction between reliability and ease of manufacture
3Manufacturing precision
If separate block out members are used, then guardrail positioning accuracy is improved, but assembly labor and time increase
Solution Approach 1:
The patent integrates the block out spacing plate directly into the one-piece plastic structure as a built-in feature. The Z-shaped design includes an integrated offset block that provides precise guardrail positioning without requiring separate block out members, thereby maintaining positioning accuracy while significantly reducing assembly labor and time
Solution Approach 2:
The one-piece plastic foundation includes self-aligning features and integrated positioning elements that automatically ensure correct guardrail placement during installation. The built-in offset block and flange geometry provide automatic positioning guidance, eliminating the need for separate positioning components and reducing assembly complexity
