Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier apparatuses for water-collecting strips on motor vehicles are complex to mount and require significant technical effort, lack easy insertion and rearward catching mechanisms, and are not cost-effective.
Innovation Solution
A carrier apparatus with orthogonal catching means and catching elements that allow for easy mounting and dismounting by inserting into through-openings of the A-pillar, using expanding rivets or elastically deformable catching arms, and a method for mounting a water-collecting strip that requires low forces and is safe and reliable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional carrier apparatuses are used to fasten water-collecting strips to A-pillars, then secure attachment is achieved, but the mounting process requires considerable technical effort and is complex
Solution Approach 1:
The carrier apparatus is divided into distinct functional components: a mounting component with catching means for the A-pillar, and a fastening component with catching elements for the water-collecting strip. This segmentation allows each component to be optimized independently and simplifies the overall mounting process.
Solution Approach 2:
The catching means is designed to automatically engage and secure itself within the through-opening of the A-pillar without requiring additional fastening steps or tools. The elastic deformability of the catching means enables self-locking through simple insertion and rearward movement.
2Productivity
If traditional connection methods (welding, adhesive, rivet) are used to attach carrier apparatuses to A-pillars, then strong connection is achieved, but the mounting process requires significant technical effort and time
Solution Approach 1:
Traditional mechanical connection methods (welding, adhesive bonding, riveting) are replaced with a purely mechanical insertion and catching mechanism. The catching means simply needs to be inserted into the through-opening and moved rearward to engage, eliminating the need for specialized equipment or complex procedures.
3Reliability
If expanding rivets or elastically deformable catching arms are used as catching means, then easy insertion and secure catching are achieved, but the structural complexity increases
Solution Approach 1:
The catching means utilizes elastic deformability as a key parameter, allowing it to be inserted in a compressed state and then expand or deform rearward to engage securely with the through-opening. This parameter change enables secure attachment without complex structural features.
4Ease of operation
If simple mounting mechanisms are used to reduce mounting forces, then ease of operation is improved, but the reliability of attachment may be compromised
Solution Approach 1:
The catching means is designed with elastic deformability, allowing it to dynamically adapt during the mounting process. The elastic material allows easy insertion with low force, then deforms to create a secure rearward catch that maintains reliable attachment under operational loads.
