Longitudinal Grate Unit Point-Symmetrical Marking for Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grates used for drainage channels lack a visually appealing pattern that spans multiple units, making them difficult to install correctly in different orientations and lacking a foolproof installation method.
Innovation Solution
A grate unit with point-symmetrical marking surfaces on filler bars that remain unchanged when rotated, allowing for continuous pattern expansion and featuring micro-grip structures for improved traction, along with integrally formed locking elements for secure installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional grates with simple patterns are used, then manufacturing is simple and cost-effective, but the visual appeal and pattern continuity across multiple units is poor
Solution Approach 1:
The patent applies asymmetry by using point-symmetrical marking surfaces on filler bars that create a visually appealing pattern when multiple grates are arranged together. The marking surfaces are positioned asymmetrically on individual filler bars but create symmetric patterns when grates are combined, resolving the contradiction between simple manufacturing and aesthetic pattern design.
2Ease of operation
If grates lack orientation indicators, then installation is flexible, but correct positioning and pattern continuity across multiple units cannot be ensured
Solution Approach 1:
The patent uses marking surfaces with different visual properties (color, texture, or reflectivity) on filler bars to provide orientation information. These markings allow installers to quickly identify correct positioning and ensure pattern continuity across multiple grates without complex instructions, resolving the contradiction between installation flexibility and orientation guidance.
3Device complexity
If grates have no locking elements, then the structure is simpler and manufacturing is easier, but secure installation and prevention of displacement are compromised
Solution Approach 1:
The patent merges the locking function with existing structural elements of the grate, integrating locking elements into the filler bars or support bars. This combination approach provides secure installation and displacement prevention without significantly increasing structural complexity or manufacturing difficulty, resolving the contradiction between simplicity and reliability.
4Illumination intensity
If marking surfaces cover large areas, then visual recognition and pattern continuity are improved, but the anti-slip function and drainage capability are reduced
Solution Approach 1:
The patent applies local quality by providing marking surfaces only on specific filler bars or specific portions of filler bars, rather than covering the entire grate surface. This localized approach maintains visual recognition and pattern continuity while preserving anti-slip properties and drainage capability on the remaining surfaces, resolving the contradiction between visual appeal and safety.
