Windshield Wiper Blocking Member for Stable Scraper Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield wiper assembly processes are hindered by interference between the scraper and latch seat, leading to difficulties in easy assembly and securement, and the scraper tends to wobble over time.
Innovation Solution
The use of a positioning slab and slot secures the blocking member on the elastic arm, with clamps retaining the elastic arm inside a channel, and guiding shields preventing rainwater infiltration, ensuring the scraper's secure attachment and preventing disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the scraper is mounted to the latch seat in the conventional assembly process, then the windshield wiper can be assembled, but the assembly process becomes difficult due to interference between the scraper and latch seat
Solution Approach 1:
The invention divides the assembly into sequential stages: first securing the blocking member to the elastic arm, then assembling the connecting strip, and finally attaching the scraper. This segmentation eliminates interference between components during assembly by establishing a proper assembly sequence, making the manufacturing process easier and more systematic.
Solution Approach 2:
The blocking member is preliminarily secured to the elastic arm before the main assembly process begins. This preliminary action prepares the structure in advance, preventing interference during subsequent assembly steps and enabling easier installation of the scraper without modifying the latch seat.
2Reliability
If the scraper is mounted to the latch seat, then the windshield wiper can be assembled, but the scraper tends to wobble after long period of use
Solution Approach 1:
The invention extracts the blocking function from the latch seat and relocates it to a dedicated blocking member attached to the elastic arm. This separation eliminates the wobble problem by providing a stable, dedicated blocking structure that does not interfere with the scraper's mounting, ensuring long-term reliability throughout the service life.
Solution Approach 2:
The blocking member acts as an intermediary element between the elastic arm and the scraper assembly. It provides the necessary blocking function while maintaining proper spacing and alignment, preventing the scraper from wobbling during extended use without requiring modifications to the latch seat structure.
3Reliability
If the elastic arm is retained inside the channel using clamps, then the elastic arm remains secure, but rainwater may infiltrate into the elastic arm inside the connecting strip
Solution Approach 1:
The invention uses a waterproof film or coating applied to the elastic arm or the interface between the elastic arm and connecting strip. This flexible protective layer prevents rainwater infiltration while maintaining the secure retention of the elastic arm within the channel through the clamp mechanism.
Solution Approach 2:
A waterproof intermediary layer (such as a sealant or protective coating) is introduced between the elastic arm and the connecting strip channel. This intermediary prevents rainwater infiltration while allowing the clamp to securely retain the elastic arm in its proper position.

AI summary
The present disclosure relates to a windshield wiper, having a latch seat (10), an elastic arm (20), a scraper (40) and a blocking member (50). The elastic arm (20) is connected to the latch seat (10) and includes an opening slot (21) formed at one end thereof. The elastic arm (20) includes a top surface (22) and a bottom surface (23). The scraper (40) is attached to the bottom surface (23) of the elastic arm (20). The blocking member (50) includes a substrate (51) attached to the top surface (22) and having a side blocking member (52) penetrating through the opening slot (21) and blocking the scraper (21) along a longitudinal direction of the elastic arm (20). Accordingly, the windshield wiper is facilitated for assembly, and the scraper may be secured effectively.
