Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote-controlled electrical vehicle mirrors face issues with water seepage into the housing through the water escape hole, leading to potential damage and operational problems.
Innovation Solution
A mirror device with a covering member and an adjusting section that includes a discharge hole and outlet system to prevent liquid from entering the adjusting section, using a restriction wall to further restrict seepage, and ensuring efficient external discharge of water through the discharge hole and outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a water escape hole is formed in the housing to discharge water, then water discharge function is improved, but water easily seeps into the housing through the water escape hole
Solution Approach 1:
Instead of having the discharge hole directly open to the exterior, the patent inverts the discharge path by having water discharged first into a covered space between the mirror and covering member, then exiting through a discharge outlet. This reversal of the discharge sequence prevents direct seepage while maintaining discharge functionality.
Solution Approach 2:
The patent introduces an intermediary space between the mirror and covering member as a mediator. This intermediate chamber receives discharged water through the discharge hole and channels it to the exterior through the discharge outlet, preventing direct contact between seeping water and the housing interior.
2Productivity
If the discharge hole opens to the exterior directly, then water discharge efficiency is improved, but liquid seeps into the adjusting section
Solution Approach 1:
The patent segments the discharge function into two separate openings: a discharge hole for efficient water ejection and a discharge outlet for controlled exterior discharge. This segmentation allows the discharge hole to maintain high discharge efficiency while the discharge outlet provides protected exit, preventing direct seepage into the adjusting section.
Solution Approach 2:
The covered space between the mirror and covering member serves as an intermediary chamber that receives water from the discharge hole and directs it to the exterior through the discharge outlet. This intermediary structure maintains discharge efficiency while preventing liquid seepage into the adjusting section.
3Object-affected harmful factors
If sealing members are added to prevent water seepage, then protection against liquid seepage is improved, but device complexity increases
Solution Approach 1:
The patent employs the mirror and covering member themselves to perform the sealing function. The covering member covers the back face of the mirror and works with the discharge hole and outlet configuration to prevent seepage, eliminating the need for additional dedicated sealing members while maintaining protection.
Solution Approach 2:
The covering member serves multiple functions: it covers the back face of the mirror, creates a covered space for water discharge, and works with the discharge hole and outlet to prevent liquid seepage. This multi-functionality eliminates the need for separate sealing members, reducing device complexity while maintaining protection.

AI summary
Suppressing liquid from seeping into an adjusting section through a discharge hole. In a vehicle door mirror device an opening hole in a holder portion of a mirror-surface adjustment-device is in communication with opening outlet of a mirror holder outer through an opening outlet in the mirror holder outer and a gap between the mirror and the mirror holder outer. Accordingly, even suppose water seeps into the mirror-surface adjustment-device through the opening hole in the holder portion, the water would be externally discharged outside the mirror holder outer through the opening hole, the opening outlet, the gap and the opening outlet. Furthermore, even suppose water at high pressure from outside the mirror holder outer is to reach the opening outlet, the water can be suppressed from seeping into the mirror-surface adjustment-device through the opening outlet and the opening hole due to the water pressure being reduced in the gap.
