Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety grilles for wall openings require extensive assembly due to numerous loose parts and often need custom-made components, complicating installation and cable passage while maintaining a small cross-sectional area for cable feedthroughs.
Innovation Solution
A modular object protection grille design featuring plug-in slats and wall connection elements that can be easily assembled and adapted on-site, allowing for flexible installation and secure cable feedthroughs without a surrounding frame, using plug-in recesses and wall connection elements for secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transverse pipes with threaded rods and multiple nuts are used to create safety grilles, then cable feedthrough capability is achieved, but assembly work increases significantly due to large number of loose parts
Solution Approach 1:
The patent combines multiple separate components (transverse pipes, threaded rods, nuts, and slats) into an integrated frame profile with built-in recesses. The frame profiles contain directly integrated cable access openings, eliminating the need for separate transverse pipes and threaded rod assemblies, thereby reducing the number of loose parts while maintaining cable feedthrough functionality.
Solution Approach 2:
The frame profiles are designed as multi-functional elements that simultaneously provide structural support, cable access, and slat mounting functions. The recesses in the frame profiles serve multiple purposes: structural integration, cable routing channels, and mounting positions for slats, consolidating several functions into a single universal component.
2Device complexity
If frame profiles with multiple recesses are used to simplify assembly, then assembly work is reduced, but custom-made components are required due to special shape
Solution Approach 1:
The safety grille system is divided into modular frame profile segments that can be manufactured using standard extrusion or molding processes. Each frame profile contains standardized recesses that can be replicated across multiple units, allowing modular assembly without requiring entirely custom-made components for each specific installation.
3Stability of the object's composition
If a surrounding frame is used to secure slats, then structural stability is improved, but adaptability to different installation conditions decreases
Solution Approach 1:
Instead of a continuous surrounding frame, the patent uses segmented frame profiles with discrete recesses positioned at specific locations. This segmentation allows the grille to be adapted to different wall opening sizes and shapes while maintaining structural stability through strategically placed support points rather than a rigid continuous frame.
Solution Approach 2:
The frame profile design allows for flexible configuration where recesses can be positioned at different locations depending on installation requirements. The modular nature enables dynamic adaptation to various wall openings and cable routing needs while maintaining the necessary structural integrity through the interlocking slat and frame configuration.
