Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a modular design with elementary lighting modules is used, then ease of assembly and repair are improved, but device complexity increases due to multiple components and connections
Solution Approach 1:
The lighting device is divided into multiple independent elementary lighting modules, each containing a LED assembly, printed circuit board, and fastening support. This segmentation allows individual modules to be easily replaced or repaired without affecting the entire device, directly improving ease of repair while managing complexity through standardized modular units.
Solution Approach 2:
The fastening support structure serves multiple functions: it mechanically fastens the elementary module to the support structure, provides electrical connection between modules, and ensures proper positioning. This multi-functionality reduces the number of separate components needed, improving ease of assembly while controlling overall device complexity.
2Reliability
If reference terminals are electrically connected via the support structure, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The support structure integrates both mechanical support and electrical connection functions. The conductive support structure simultaneously provides structural integrity and establishes electrical connections between reference terminals of adjacent modules, improving reliability through unified construction while simplifying manufacturing by combining multiple functions into a single component.
Solution Approach 2:
The support structure serves dual purposes: it acts as the mechanical framework for mounting modules and as the electrical pathway for connecting reference terminals. This multi-functionality ensures reliable electrical connections while reducing manufacturing steps, as the same structure performs both support and connection roles.
3Reliability
If electronic control circuit monitors inflation fan rotation speed, then reliability is improved through defect detection, but device complexity increases
Solution Approach 1:
The electronic control circuit continuously monitors the rotation speed of the inflation fan and uses this feedback to detect defects such as cavitation, leaks, or clogging. When abnormal conditions are detected, the system can alert users or adjust operation, improving reliability through real-time monitoring while adding controlled complexity through the sensing and control system.
Solution Approach 2:
The system performs self-diagnosis by monitoring its own operational parameters (fan rotation speed) and automatically detecting defects without external intervention. This self-service capability improves reliability through continuous health monitoring while managing complexity by using the existing control infrastructure for diagnostic functions.
