Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hook elements are used for module fixation, then modules can be attached to mounting strips, but stable positioning and fixation require complex devices and additional fixation means
Solution Approach 1:
The connection device is segmented into two functional parts: T-shaped connection bars on the mounting strip and receiving slots in the module housings. This segmentation allows each part to have a specialized function - the T-shaped bars provide structural support and positioning, while the receiving slots enable easy insertion and secure engagement, eliminating the need for complex additional fixation means
Solution Approach 2:
The T-shaped connection bars and receiving slots form a self-service connection system where the module housing automatically positions itself onto the mounting strip through the gliding cooperation. The friction-based force transmission and raster alignment provide self-centering and self-fixation capabilities, eliminating the need for operators to use additional tools or complex fixation procedures
2Ease of operation
If simple connection devices are used, then handling is simplified, but stable positioning and fixation of modules becomes difficult
Solution Approach 1:
The connection device utilizes parameter changes through friction-based force transmission. As the module housing is inserted onto the T-shaped connection bar, the normal force increases, which in turn increases the friction force proportionally. This friction force automatically adapts to secure the module firmly without requiring additional complex fixation mechanisms, achieving both simple handling and reliable fixation
Solution Approach 2:
The connection system combines multiple functional elements into a composite structure: the T-shaped connection bars provide mechanical support, the receiving slots enable guided insertion, and the friction-based interaction between surfaces provides secure fixation. This composite approach integrates positioning, guidance, and fixation functions into a single simple connection device
3Productivity
If modules are positioned without raster alignment, then installation is faster, but exact positioning and alignment along the mounting strip is compromised
Solution Approach 1:
The T-shaped connection bars and receiving slots serve multiple functions simultaneously: they provide structural connection, enable raster-based exact positioning through their spaced arrangement, and facilitate easy insertion through gliding cooperation. This multi-functionality allows the same simple connection device to achieve both rapid installation and precise alignment without requiring separate positioning mechanisms
Solution Approach 2:
The raster structure of T-shaped connection bars and receiving slots provides self-aligning capabilities. When a module housing is inserted, the receiving slot automatically guides it onto the correct T-shaped connection bar, ensuring exact positioning in the raster pattern without requiring manual alignment or complex positioning tools, thus maintaining both speed and precision
4Manufacturing precision
If connection bars are spaced at equal distances forming a raster, then exact positioning is achieved, but the structure becomes more complex
Solution Approach 1:
The T-shaped connection bars are uniformly designed with identical geometry and are spaced at equal distances along the mounting strip. This homogeneity in design and spacing simplifies manufacturing while achieving exact positioning through the regular raster pattern. The uniformity allows for standardized production and easy assembly without requiring complex variable-geometry components
