Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hole is formed in the body to transmit electric signals between components, then electrical connectivity is improved, but waterproof performance deteriorates due to water ingress through the hole
Solution Approach 1:
The signal connection unit is nested within the housing, which is then nested within the body hole. The waterproof packing is mounted on the housing to seal the entire assembly. This nested structure allows the signal transmission function to be integrated within a waterproof enclosure, solving both electrical connectivity and waterproofing requirements simultaneously.
Solution Approach 2:
The housing acts as an intermediary structure between the body hole and the signal connection unit. It provides a protective enclosure that can be sealed with waterproof packing, while still allowing electrical signals to pass through the signal connection unit. This intermediary structure mediates between the conflicting requirements of open signal transmission and closed waterproofing.
2Object-affected harmful factors
If a waterproof structure is implemented to seal the hole, then waterproof performance is improved, but signal transmission capability deteriorates due to potential signal interference or connection complexity
Solution Approach 1:
The signal connection unit is nested within the housing, which is then nested within the body hole. The waterproof packing is mounted on the housing to seal the entire assembly. This nested structure allows the signal transmission function to be integrated within a waterproof enclosure, solving both electrical connectivity and waterproofing requirements simultaneously.
Solution Approach 2:
The housing is designed with specific local properties: it has a hollow interior to accommodate the signal connection unit, and its exterior is designed to interface with the body hole. The waterproof packing is applied locally at the interface between the housing and body hole, providing sealing without interfering with the signal transmission function of the signal connection unit.
3Object-affected harmful factors
If a signal connection module with housing and waterproof packing is used to seal the hole, then waterproof performance is improved, but device complexity increases due to additional components
Solution Approach 1:
The signal connection module merges multiple functions into a single integrated assembly: the housing provides structural support and accommodation for the signal connection unit, while also serving as the mounting base for the waterproof packing. This combination of functions into a single module reduces the number of separate components needed and simplifies the overall assembly process.
Solution Approach 2:
The housing serves multiple functions: it provides a protective enclosure for the signal connection unit, acts as a mounting structure for the waterproof packing, and interfaces with the body hole. This multi-functionality reduces the need for separate dedicated components for each function, thereby reducing overall device complexity.
