Windshield Scrubbing Bag with Abrasive Zone and Resilient Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield scrubbing devices are inadequate for effectively removing insects and debris without damaging the windshield, as they either require manual scrubbing or may abrade the surface during cleaning.
Innovation Solution
A scrubbing device comprising a bag made of abrasive material positioned around a windshield wiper with a resilient wiping blade that frictionally engages the windshield, allowing for automatic removal of insects and debris without abrading the surface, utilizing an elastomeric band to secure the bag around the wiper and a compressible wiping blade for moisture removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an abrasive scrubbing device is used to remove insects and debris from the windshield, then cleaning effectiveness is improved, but the windshield surface may be abraded and damaged
Solution Approach 1:
The scrubbing device is segmented into distinct functional zones: a hard abrasive portion for removing stubborn insects and debris, and a soft resilient portion for general cleaning and moisture removal. This segmentation allows each zone to perform its specific function without the hard abrasive material contacting the windshield directly, thus maintaining cleaning effectiveness while preventing surface damage.
Solution Approach 2:
Different portions of the scrubbing device have different material properties tailored to specific cleaning needs. The abrasive portion contains hard particles for tough contaminants, while the resilient portion contains soft compressible material for gentle wiping. This local differentiation of material quality enables effective cleaning without windshield damage.
2Object-affected harmful factors
If manual scrubbing is used to clean the windshield, then windshield surface damage is avoided, but cleaning efficiency and productivity are reduced
Solution Approach 1:
The scrubbing device is designed to be mounted on the vehicle's existing windshield wiper system, allowing it to automatically clean the windshield during normal wiper operation. This self-service approach eliminates the need for separate manual scrubbing actions while maintaining windshield protection, thereby improving cleaning efficiency without requiring additional manual effort.
3Productivity
If a hard abrasive material is used for scrubbing, then removal of insects and debris is improved, but the device may abrade the windshield surface
Solution Approach 1:
The hard abrasive particles are extracted from the main body of the scrubbing device and contained within a separate abrasive portion or chamber. This allows the abrasive material to be used effectively for removing insects and debris while being isolated from direct contact with the windshield surface. The abrasive portion can be replaced or replenished without replacing the entire scrubbing device.
4Object-affected harmful factors
If a soft resilient material is used for wiping, then windshield surface protection is improved, but effectiveness in removing precipitation is reduced
Solution Approach 1:
The resilient wiping portion is designed to be compressible and adaptable to the windshield surface contours. As the wiper system applies pressure, the resilient material dynamically compresses to conform to the glass surface, maximizing contact area and effectiveness for precipitation removal. The dynamic compression and recovery of the material maintains both gentleness on the surface and effectiveness in water removal.
