Solution Overview
Problem
The complexity and cost associated with producing multiple wiper blade configurations to accommodate various wiper arm configurations have created a challenge in the replacement market, as existing solutions require multiple designs to fit different arm types, leading to inefficiencies in coupling wiper blades with wiper arms.
Innovation Solution
A connector design featuring side walls with a bridge, rivet passage, and reinforcement elements that can accommodate different wiper arm types, including hook and pin configurations, providing a strong and adaptable coupling mechanism to reduce the need for multiple blade configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wiper blade configurations are produced to accommodate various wiper arm configurations, then compatibility with different arm types is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The connector is designed with a universal structure that can accommodate multiple wiper arm configurations (hook-type, pin-type, and other variations) through a single standardized design. The connector includes a channel that can receive different arm types and a securing mechanism that adapts to various configurations, eliminating the need for multiple specialized blade designs while maintaining full compatibility across all arm types.
2Adaptability or versatility
If multiple wiper blade configurations are produced to accommodate various wiper arm configurations, then compatibility with different arm types is improved, but manufacturing cost increases
Solution Approach 1:
The connector uses a standardized universal design that can be manufactured using single molding processes and consistent tooling, significantly reducing manufacturing costs compared to producing multiple specialized configurations. The single-configurability approach allows for economies of scale while maintaining compatibility with all wiper arm types through adaptive features within the unified design.
3Strength
If a robust connector design with reinforcement elements is used, then resistance to torque forces is improved, but device complexity increases
Solution Approach 1:
The connector incorporates pre-positioned reinforcement elements and support structures that are integrated into the base design before assembly. These elements are strategically placed to preemptively strengthen high-stress areas where torque forces are applied, ensuring robust performance without requiring complex additional components or post-assembly modifications.
Solution Approach 2:
The connector utilizes composite construction combining multiple materials with complementary properties - such as rigid plastics for structural strength and flexible elements for adaptation - to achieve high torque resistance. This composite approach allows the connector to maintain simplicity in form while achieving superior strength characteristics through material selection and layered construction.

AI summary
Novel connectors for coupling wiper blades with arms are described, including those that. A wiper blade connector may include first and second side walls and a bridge defining an upper channel, as well as a passage for receiving a rivet or pin. The connector may also include a reinforcement portion which may be an extension of the side walls, include a portion overhanging into the upper channel, an outward extension projecting in a direction away from the upper channel, or resilient tabs on the inside of the channel. The connector may also include a support element, such as a truss member, which extends the upper channel. A lateral brace may also be provided between side walls.
