Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional bar code reader structure is used, then the device can perform bar code reading function, but the device becomes too large and complicated to be portable and easily assembled
Solution Approach 1:
The bar code reader is divided into separate modules including a casing, a bar code reading unit, a button, and a main board that can be independently assembled and disassembled. This segmentation allows for easier manufacturing and maintenance while reducing the overall structural complexity through modular design.
Solution Approach 2:
Multiple functional components are merged into an integrated compact structure where the casing encapsulates the main board, bar code reading unit, and button in a unified housing. This merging reduces the number of separate parts and simplifies assembly while maintaining all necessary functions.
2Ease of operation
If a conventional bar code reader structure is used, then the device can perform bar code reading function, but the device becomes too large to be carried conveniently in a pocket
Solution Approach 1:
The bar code reading unit, button, and main board are nested within the compact casing structure, with components arranged in a space-efficient manner. This nesting approach minimizes the external dimensions of the device while accommodating all internal components, making it suitable for portable use.
Solution Approach 2:
The device utilizes three-dimensional space optimization by arranging components vertically and horizontally within the casing to maximize compactness. This dimensional optimization reduces the overall volume of the bar code reader while maintaining functional integrity.
3Ease of operation
If a compact bar code reader is designed, then the device becomes portable and easy to carry, but the assembly and disassembly process becomes more difficult
Solution Approach 1:
The device is segmented into modular components with standardized connection interfaces that enable easy assembly and disassembly. This segmentation allows users to quickly assemble or disassemble the device without complex tools or procedures, maintaining both portability and ease of manufacture.
Solution Approach 2:
The casing design incorporates universal mounting structures and standardized connection points that can accommodate various internal components. This universality simplifies the assembly process by allowing interchangeable parts and reduces the complexity of manufacturing through standardized procedures.
