Tool-Free Cable Penetration Frame with Interlocking Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable duct frame systems are cost-intensive and prone to assembly errors due to their complex sub-components and require tools, leading to potential damage and loose connections under cable tension.
Innovation Solution
A frame system comprising identical first and second frame parts with receptacles and projections, featuring locking elements with clamping or sliding mechanisms that allow for pre-centering and secure connection without tools, ensuring reliable assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If snap-in elements are used to enable insertion and release of frame parts, then ease of assembly is improved, but the frames become elastic and easily deformed under cable tension
Solution Approach 1:
The frame is divided into multiple frame parts that can be separately assembled and disassembled. Each frame part contains locking elements that provide both easy connection and stable fixation, resolving the contradiction between ease of assembly and frame stability through modular segmentation.
2Strength
If screw connections are used to secure frame parts, then connection strength is improved, but assembly requires tools and becomes time-consuming with risk of improper assembly
Solution Approach 1:
The locking elements are designed to automatically engage and lock frame parts together without requiring external tools. The self-servicing mechanism provides strong connections through automated interlocking, eliminating the need for screwdrivers or other assembly tools while maintaining connection strength.
3Adaptability or versatility
If multiple different sub-components are used in frame construction, then adaptability is improved, but production cost increases and assembly becomes prone to errors
Solution Approach 1:
The frame parts are designed with universal characteristics where identical or similar components can serve multiple functions and positions within the frame structure. The standardized locking elements and frame part geometry allow for versatile configurations using the same basic components, reducing the total number of different sub-components needed while maintaining design flexibility.

AI summary
The invention relates to a frame (1) for cable penetration systems. The frame (1) comprises a first frame part (10, 30) and a second frame part (10', 30'), each of which (10, 10', 30, 30') includes a receptacle (19, 19', 39, 39') and a projection (18, 18', 38, 38'). The projection (18; 38) of the first frame part (10, 30) is designed to be insertable into the receptacle (19, 39') of the second frame part (10'; 30'), and the projection (18', 38') of the second frame part (10', 30') is designed to be insertable into the receptacle (19, 39) of the first frame part (10, 30). The first frame part (10, 30) further includes a locking element (11, 31), and the second frame part (10', 30') also includes a locking element (11', 31'), the locking elements (11, 11', 31, 31') being able to releasably connect the first frame part (10, 30) to the second frame part (10', 30') in the assembled state. Locking elements (31, 31') are provided with clamp clips, while locking elements (11, 11') are provided with sliding elements. The invention further relates to frame parts (10, 10', 30, 30').
