Rear Spoiler Access Structure for Concealed Wiper Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle spoiler assemblies do not effectively conceal and provide access to rear wiper apparatuses, which can lead to visibility issues and maintenance challenges.
Innovation Solution
A vehicle spoiler assembly designed to cover the wiper motor and blade while allowing access, featuring a pivotable or removable design that conceals the wiper apparatus when not in use and allows easy access for maintenance by pivoting or using an access opening with a cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the spoiler assembly completely covers the wiper apparatus, then aesthetics are improved, but access for maintenance becomes difficult
Solution Approach 1:
The spoiler assembly is divided into a fixed portion and a movable access portion. The access portion can be pivoted or removed separately from the main spoiler body, allowing maintenance personnel to access the wiper apparatus while preserving the overall aesthetic appearance of the spoiler when closed.
Solution Approach 2:
An access opening or removable cover is introduced as an intermediary element between the spoiler assembly and the wiper apparatus. This intermediary allows selective access to the wiper motor and blade while maintaining the concealing function of the spoiler during normal operation.
2Ease of repair
If the spoiler assembly is designed with access openings, then maintenance access is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The access opening is designed as a dynamic feature that can be opened or closed as needed. The access portion of the spoiler can be pivoted to an open position during maintenance and returned to a closed position during normal operation, allowing the aesthetic appearance to be preserved when access is not required.
Solution Approach 2:
The access opening or removable cover is designed as a simple, easily replaceable component that can be quickly removed or opened for maintenance and then restored, prioritizing ease of access over permanent aesthetic perfection.
3Shape
If the wiper apparatus is completely concealed, then aesthetics are improved, but visibility of wiper status becomes difficult
Solution Approach 1:
The spoiler assembly incorporates transparent or translucent portions that allow visual detection of the wiper blade position and status while maintaining the concealing function. The transparent sections enable observers to see whether the wiper blade is in the stowed or extended position without compromising the overall aesthetic appearance.
4Strength
If the spoiler assembly is made solid and fixed, then structural strength is improved, but access for maintenance becomes difficult
Solution Approach 1:
The spoiler assembly is segmented into a strong, fixed main body that provides structural support and aesthetic appearance, and a separate, movable access portion that can be opened or removed. This segmentation allows the majority of the spoiler to maintain structural integrity while providing controlled access to the wiper apparatus through the movable portion.

AI summary
A vehicle spoiler assembly includes a vehicle body structure having a rear window, a rear wiper assembly and a spoiler. The rear wiper apparatus has a motor and a wiper blade arm installed to the vehicle body structure above the rear window. The motor is operable to move the wiper blade arm between a stowed orientation and rear window wiping position such that during movement between the stowed orientation and the rear window wiping position the wiper blade arm moves over and wipes a majority of an outer surface of the rear window. The spoiler attached to the vehicle body structure covers the motor of the rear wiper apparatus and the wiper blade arm with the wiper blade arm in the stowed orientation, at least a portion of the spoiler is configured to access the motor of the rear wiper apparatus.
