Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw fixation method is used to install circuit board on bracket, then the connection is reliable and firm, but the assembly and disassembly process becomes complicated and time-consuming
Solution Approach 1:
The connection structure is segmented into a guide column on the circuit board and a corresponding guide hole on the bracket, allowing for easy alignment and insertion. This segmentation enables the circuit board to be quickly positioned and secured without complex screw alignment procedures, resolving the contradiction between reliable connection and ease of assembly.
Solution Approach 2:
A guide structure consisting of guide columns and guide holes serves as an intermediary mechanism between the circuit board and bracket. This intermediary structure facilitates easy alignment and insertion while ensuring stable connection, thereby improving assembly convenience without compromising connection reliability.
2Manufacturing precision
If precise hole alignment is required for screw installation, then the connection accuracy is improved, but the assembly process becomes more complex and difficult to disassemble
Solution Approach 1:
The guide columns and guide holes are pre-formed on the circuit board and bracket respectively, establishing precise alignment paths before the actual assembly operation. This preliminary preparation eliminates the need for complex real-time alignment during assembly, reducing process complexity while maintaining manufacturing precision.
Solution Approach 2:
The guide structure enables self-alignment during assembly, where the guide columns automatically fit into the guide holes without requiring external alignment tools or complex positioning procedures. This self-service mechanism simplifies the assembly process while ensuring precise hole alignment.
3Stability of the object's composition
If multiple circuit boards are installed together using traditional methods, then the structural stability is maintained, but the assembly and disassembly time increases significantly
Solution Approach 1:
Each circuit board is equipped with its own guide columns that independently engage with corresponding guide holes in the bracket or adjacent boards. This segmentation allows multiple circuit boards to be assembled simultaneously or sequentially without interfering with each other, maintaining structural stability while reducing total assembly time.
Solution Approach 2:
The guide structure integrates positioning and connection functions into a single mechanism, combining the alignment and fixation operations that would otherwise require separate screw installation steps. This merging of functions enables rapid assembly of multiple circuit boards while maintaining stable structural composition.
