Top-lock Wiper Blade Adapter Blocking Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing top-lock wiper blade adapters face issues with incorrect installation due to differences in width between wiper arm adapters, leading to malfunctions and unintended releases.
Innovation Solution
A top-lock wiper blade adapter with a blocking unit featuring overlap elements and side walls that prevent wider wiper arm adapters from locking, ensuring secure and correct installation by forming receiving pockets and using stop edges to block misaligned adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the top-lock wiper blade adapter is designed to accommodate standard wiper arm adapters, then compatibility is maintained, but wider adapters can be incorrectly installed causing malfunctions
Solution Approach 1:
The blocking unit with overlap elements is pre-configured on the wiper blade adapter to prevent incorrect installation of wider adapters before they can cause malfunctions. The overlap elements extend laterally to physically block the engagement of adapters exceeding the specified width, thereby preventing erroneous installation in advance.
Solution Approach 2:
The blocking unit acts as an intermediary element between the wiper blade adapter and the wiper arm adapter. It mediates the connection by allowing proper adapters to engage while preventing wider adapters from being installed, thus ensuring installation correctness without compromising compatibility.
2Reliability
If the blocking unit with overlap elements is added to prevent incorrect installation, then installation correctness is improved, but device complexity increases
Solution Approach 1:
The blocking unit is merged with the main body of the wiper blade adapter as an integrated component. The overlap elements are formed as part of the adapter's structure, combining the blocking function with the existing adapter design rather than adding separate external components, thus minimizing the increase in device complexity.
Solution Approach 2:
The blocking function is implemented locally at specific positions where overlap elements extend laterally from the main body. Rather than redesigning the entire adapter structure, the blocking features are added only at the necessary locations to prevent incorrect adapter installation, maintaining simplicity while improving reliability.

AI summary
The invention proceeds from a top-lock wiper blade adapter for coupling a wiper blade to a corresponding top-lock wiper arm adapter (10), having at least one main body (12) and at least one locking element (14) which is provided for locking the main body (12) to the top-lock wiper arm adapter (10). It is proposed that the top-lock wiper blade adapter has a blocking unit (16), which comprises at least one engagement element (18, 20) which engages at least partially over at least one inner abutment surface (22, 24) of the main body (12) and is provided to avoid the locking of a top-lock wiper arm adapter (26) which deviates from the corresponding top-lock wiper arm adapter (10) in terms of width (28).
