Fiberglass Box Pad Corner Protector for Mower Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The corners of fiberglass box pads used for electrical and communication boxes are vulnerable to damage from yard equipment, leading to structural breaks that compromise the integrity and safety of the boxes, requiring costly and labor-intensive repair methods.
Innovation Solution
The development of corner protectors made from high-density polyethylene, featuring a central protrusion with a pointed blade and lip design, which can be installed on the fiberglass box pads to prevent damage from equipment like mowers and tractors, thereby extending the life of the pads and reducing maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corner protectors are installed on fiberglass box pads, then damage prevention and structural integrity are improved, but device complexity and installation cost increase
Solution Approach 1:
The corner protector is divided into two main segments: a first plate positioned vertically and a second plate positioned horizontally, with the second plate substantially perpendicular to the first plate. This segmentation allows each plate to perform its specific protective function independently while working together to provide comprehensive corner protection.
Solution Approach 2:
The corner protector transitions from a two-dimensional surface patch to a three-dimensional L-shaped structure by positioning the second plate substantially perpendicular to the first plate. This dimensional change provides protection on multiple surfaces simultaneously, preventing damage from various directions.
2Reliability
If corner protectors are installed during or after box pad installation, then preventative protection is achieved, but installation time and labor cost increase
Solution Approach 1:
The corner protector is designed to be installed during the box pad installation process itself, rather than as a separate subsequent step. The L-shaped structure can be positioned and secured while the box pad is being placed, integrating the protective measure into the primary installation workflow.
Solution Approach 2:
The corner protector features a self-aligning design where the first and second plates naturally orient themselves to protect the corner. The structure's geometry provides inherent positioning guidance, reducing the need for complex alignment procedures and specialized installation tools.
3Ease of repair
If reactive repair methods are used for damaged box pads, then damage is addressed, but maintenance cost and labor intensity increase
Solution Approach 1:
The corner protector applies preliminary protective action by physically blocking yard equipment and other harmful objects from contacting the box pad corner. This preventive measure eliminates the need for subsequent repair actions by stopping damage before it occurs.
Solution Approach 2:
The corner protector serves as an intermediary element between the box pad and external harmful factors such as mowers, trimmers, and shovels. This intermediate structure absorbs and distributes impact forces, protecting the vulnerable box pad corner from direct contact with damaging objects.
