Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a bracket assembly is used to maintain fixed spacing between vision system modules, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The bracket assembly integrates multiple support functions into a single structural component that simultaneously holds the camera module and light emitter at fixed positions. This merging of support, alignment, and spacing functions into one bracket structure maintains manufacturing precision while reducing the number of separate components needed.
Solution Approach 2:
The bracket assembly serves as an intermediary component between the housing and the vision system modules (camera and light emitter). It provides a stable mounting platform that ensures precise spacing without requiring direct attachment of each module to the housing, thereby simplifying the overall assembly process.
2Ease of operation
If the bracket assembly is not affixed to the housing, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The bracket assembly is designed to be movable during the assembly process, allowing it to be easily positioned and aligned with the housing and display assembly. Once assembled, the bracket maintains the vision system modules in their correct positions, providing stability without requiring permanent affixation to the housing.
Solution Approach 2:
The bracket assembly is pre-positioned and aligned with the display assembly before final assembly with the housing. This preliminary alignment ensures that the vision system modules are correctly positioned relative to the display notch, and the bracket maintains this positioning throughout the assembly process without requiring affixation to the housing.
3Ease of manufacture
If the display assembly includes a notch for the vision system, then ease of manufacture is improved, but the display area is reduced
Solution Approach 1:
The display assembly features a localized notch only in the specific region where the vision system modules are positioned, rather than reducing the entire display area. This localized modification maintains the display quality and area in all other regions while providing the necessary access point for the camera and light emitter.
Solution Approach 2:
The notch in the display assembly is positioned asymmetrically at the top center of the display, corresponding to the location of the vision system modules. This asymmetric placement allows the vision system to be aligned with the display without requiring a symmetric reduction of the display area, thereby minimizing the impact on overall display real estate.
4Ease of operation
If wireless charging module is added for inductive charging, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The wireless charging module integrates multiple functions into a single component, including the charging coil, magnetic shielding, and control circuitry. This universal component provides wireless charging capability while also managing power transfer and protecting against interference, thereby reducing the need for separate components and minimizing the increase in device complexity.
5Volume of moving object
If L-shaped battery components are used, then volume of moving object is improved, but manufacturing precision is worsened
Solution Approach 1:
The battery assembly transitions from a traditional linear arrangement to an L-shaped configuration that utilizes three-dimensional space more effectively. The first and second battery components are arranged perpendicular to each other, allowing the battery assembly to fit into the available volume within the housing more efficiently while maintaining proper alignment through the housing structure.
