Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wiper systems require multiple brackets to accommodate different wiper arm swing ranges and mounting positions, leading to increased design and production complexity and costs.
Innovation Solution
A bracket with multiple mechanical stoppers that can be selectively activated or deactivated to restrict the motor crank's movement within specific swing ranges, allowing a single bracket to adapt to various applications by adjusting the stoppers' orientation and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple brackets are used to accommodate different wiper arm swing ranges and mounting positions, then the system can adapt to various applications, but the design and production complexity and costs increase
Solution Approach 1:
The bracket is designed with multiple mechanical stoppers that can be selectively activated or deactivated to restrict the motor crank's movement within different swing ranges. This allows a single bracket design to accommodate various wiper arm swing ranges and mounting positions, eliminating the need for multiple specialized brackets and thereby reducing design complexity while maintaining adaptability.
Solution Approach 2:
The bracket incorporates mechanical stoppers that can be selectively activated or deactivated based on the required swing range. This dynamic configuration allows the bracket to adapt to different applications by adjusting which stoppers are engaged, enabling a single static component to provide multiple functional configurations.
2Adaptability or versatility
If multiple brackets are used to accommodate different wiper arm swing ranges and mounting positions, then the system can adapt to various applications, but the production costs increase
Solution Approach 1:
The bracket integrates multiple mechanical stoppers into a single component design, allowing it to serve multiple mounting positions and swing range requirements. This universal design eliminates the need to manufacture multiple different bracket types, thereby reducing production costs through economies of scale and simplified manufacturing processes.
Solution Approach 2:
The invention combines multiple bracket variations into a single integrated component with selectable mechanical stoppers. By merging what would traditionally require separate parts into one unified bracket design, the production process is simplified and costs are reduced while maintaining the ability to accommodate different mounting positions.
3Adaptability or versatility
If multiple brackets are used to accommodate different wiper arm swing ranges and mounting positions, then the system can adapt to various applications, but the overall system complexity increases
Solution Approach 1:
The bracket with multiple selectable mechanical stoppers provides a universal solution that replaces multiple specialized brackets. This reduces system complexity by consolidating multiple components into one, while maintaining the flexibility to configure different swing ranges through simple selection of which stoppers to activate.

AI summary
The present invention proposes a bracket (2) for an electrical motor (1) having a motor crank (4), said bracket (2) having a bracket body (6) and a plurality of mechanical stoppers (1A, 2A, 1B, 2B) extending from the bracket body (6) and forming two or more pairs of mechanical stoppers, different pair of mechanical stoppers (1A, 2A; 1B, 2B) being capable of restricting the movement of the motor crank (4) within different swing ranges. When this bracket (2) is applied to the electrical motor (1), only two of the plurality of mechanical stoppers of the bracket (2) are in activated state of restricting the movement of the motor crank (4), while the other mechanical stoppers are in deactivated state of not restricting the movement of the motor crank (4).
