Ingress-Protected Housing Structure for Multi-Orientation Water Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ingress protection mechanisms for telematics modules, such as enclosures, are not optimally effective, particularly in non-optimally oriented configurations, leading to inadequate water ingress protection.
Innovation Solution
A housing design featuring a receiving part with a first wall structure shorter than a second wall structure, forming a channel or groove, and a mating portion with a protrusion, such as a lip, that can be received by the receiving part to form an enclosure capable of providing water ingress protection regardless of orientation, enhanced by a seal portion for improved contact between housing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional enclosure design is used for telematics modules, then the structure is simple and easy to manufacture, but ingress protection (water resistance) is not optimally provided, especially in non-optimally oriented configurations
Solution Approach 1:
The housing employs asymmetric wall structures where the first wall structure is shorter than the second wall structure. This asymmetric design creates a channel that effectively blocks water ingress from above while maintaining structural simplicity. The protrusion on one housing part fits into the channel formed by the asymmetric walls, creating an orientation-independent seal without requiring complex multi-layer structures.
2Reliability
If the first wall structure is made shorter than the second wall structure to form a channel, then water ingress is impeded effectively, but the manufacturing precision requirements increase
Solution Approach 1:
The housing design uses self-aligning features where the protrusion on one housing part automatically positions itself within the channel formed by the asymmetric wall structures during assembly. This self-positioning mechanism compensates for minor dimensional variations in the wall structures, reducing the stringency of manufacturing precision requirements while maintaining effective water ingress protection.
3Adaptability or versatility
If a protrusion interface is used between housing parts, then multi-orientation protection is achieved, but the device complexity increases
Solution Approach 1:
The protrusion-channel interface serves multiple functions simultaneously: it provides mechanical connection between housing parts, creates a seal against water ingress, and enables multi-orientation protection by maintaining the seal regardless of housing orientation. This multi-functional design achieves adaptability without proportionally increasing complexity, as a single structural feature accomplishes multiple protective goals.

AI summary
A housing may, for example, include a housing part which may include a receiving part. The receiving part may, for example, include a first wall structure and a second wall structure. The second wall structure may be opposing the first wall structure. Moreover, the first wall structure may be shorter as compared to the second wall structure. The housing may further include a housing portion which may be coupled to the housing part. The housing part and the housing portion, when coupled, may form an enclosure which may be associated with an enclosed area within which one or more components may be carried. The component(s) may, for example, be carried in a manner such that Ingress Protection (e.g., water Ingress Protection) may be facilitated.
