Modular Corner Guard with Lattice Interior and Magnetic Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner guards or protectors do not provide continuous coverage for corners or edges of varying lengths, as they are typically fixed in length and cannot be easily extended or adapted to different dimensions.
Innovation Solution
A modular corner guard composed of elongated wall sections with lattice interiors and flaring tongues and recesses that allow for end-to-end connection and locking, featuring magnets or adhesives for attachment, enabling adjustable length protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-length corner guards are used, then manufacturing and installation are simple, but continuous coverage for corners of varying lengths cannot be achieved
Solution Approach 1:
The corner guard is divided into multiple modular segments that can be connected end-to-end. Each segment has standardized connection features (tongue and groove joints, magnetic connectors) allowing them to be assembled into continuous protection of varying lengths. This segmentation enables the guard to adapt to different corner lengths while maintaining simple individual segment construction.
Solution Approach 2:
The corner guard system transitions from fixed-length to adjustable-length configuration. Multiple segments can be dynamically assembled or disassembled based on the specific corner protection needs, allowing the total length to be customized while keeping each individual segment relatively simple in design.
2Adaptability or versatility
If modular segments are introduced to achieve continuous coverage, then adaptability to various lengths is improved, but connection and assembly complexity increases
Solution Approach 1:
Traditional mechanical fastening systems (screws, bolts, clips) are replaced with magnetic connection mechanisms. The magnetic segments automatically attract and hold adjacent segments together through magnetic force, eliminating the need for manual fastening operations. This substitution maintains adjustable length capability while dramatically simplifying assembly and disassembly operations.
Solution Approach 2:
The connection features of adjacent segments are designed to nest together precisely. The tongue of one segment fits into the groove of the adjacent segment, creating a self-aligning, self-latching connection. This nested design ensures proper alignment and secure connection without requiring complex adjustment procedures, thereby maintaining ease of operation despite modular complexity.
3Weight of moving object
If lattice interior structure is used, then material usage and weight are reduced, but structural strength may be compromised
Solution Approach 1:
The corner guard segments incorporate a lattice or honeycomb interior structure that provides high strength-to-weight ratio. The geometric pattern of the lattice distributes applied loads across multiple struts and nodes, maintaining structural integrity while using significantly less material than solid construction. This porous architecture achieves both weight reduction and adequate protection strength.
Solution Approach 2:
The corner guard combines the lattice interior structure with an outer protective shell and connection features to create a composite construction. The lattice core provides structural rigidity and impact resistance, while the outer shell provides surface protection and houses magnetic or mechanical connection mechanisms. This composite approach optimizes both weight and strength characteristics for effective corner protection.

AI summary
A modular corner guard is constructed of two elongated, wall sections that are disposed generally at right angles to each other. The wall sections include generally planar exterior surfaces that intersect a juncture wall or end wall that in essence creates a truncated or beveled outer corner at the exterior of the corner guard. The wall sections at the opposite sides from the juncture wall are in the form of curved or rounded exterior edge portions. The interior of the modular corner guard is constructed in the form of a lattice of open cells defined by spaced apart partition walls that extend transversely relative to the length of the wall sections. The inward edges of the partition walls lie in a common plane to cooperatively form the two interior surfaces of the modular corner guard. These two interior surfaces are disposed at right angles to each other, to enable the interior surfaces to overlie and bear against the corner of the structure on which the corner guard is mounted.
