Wiper Arm Cap with Rotation Zone for Motor Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windscreen wiper systems for motor vehicles face challenges in designing a cap that provides effective protection and aesthetic continuity while allowing easy access to the motorized shaft, ensuring a robust mechanical connection without protruding parts that could cause damage or injury in collisions.
Innovation Solution
A cap with a first portion covering the wiper arm and a second portion featuring a rotation zone and locking zone, allowing the cap to securely attach to the driving arm with a rotation mechanism and locking mechanism, ensuring secure engagement and easy removal for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cap is used to cover the motorized shaft and driving arm, then protection and aesthetic continuity are improved, but access to the motorized shaft for maintenance becomes difficult
Solution Approach 1:
The cap is divided into two functional portions: a first portion that covers the motorized shaft for protection and aesthetics, and a second portion with attachment means that enables controlled access. This segmentation allows the cap to simultaneously provide continuous protection while facilitating maintenance through the removable second portion.
Solution Approach 2:
The attachment means incorporates a rotation zone that allows the cap to rotate relative to the driving arm during the angular back-and-forth motion, while a locking zone secures the cap in position. This dynamic design enables the cap to adapt to the motion requirements while maintaining protection and allowing access when needed.
2Strength
If the cap is securely attached to the driving arm, then mechanical connection robustness is improved, but the cap cannot be removed for maintenance
Solution Approach 1:
The attachment means is designed with a rotation zone that allows relative movement during operation, ensuring robust mechanical connection during the angular back-and-forth motion, while the locking zone enables secure attachment that can be deliberately released for maintenance. This dynamic design reconciles the need for both strong connection and removability.
3Object-affected harmful factors
If protruding parts are eliminated for safety, then protection against injury is improved, but access to internal components becomes restricted
Solution Approach 1:
The cap's segmented design with distinct first and second portions allows the main body to remain covered for safety, while the second portion with attachment means provides controlled access to the motorized shaft. This segmentation maintains safety by eliminating permanent protruding parts while enabling maintenance through the removable section.
