Assembly Type Cowl Top Cover with Detachable Fastening Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional integral type cowl top covers require complex and large molds for production, leading to increased manufacturing costs and difficulty in modifying the molds due to the need for separate side molds to form inclined hook parts, resulting in inefficient and costly production processes.
Innovation Solution
An assembly type cowl top cover where fastening hooks are formed as separate parts and assembled to the cover body, reducing mold size and complexity, allowing for standardization and easier modification, with grooves and projections ensuring secure engagement and waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fastening hooks are formed integrally with the cowl top cover, then the cowl top cover can be manufactured as a single piece, but the mold size and complexity increase due to the need for separate side molds to form inclined hook parts
Solution Approach 1:
The fastening hook is divided into two separate components: the cowl top cover body and the detachable fastening hook. This segmentation allows the main cover to be manufactured using a simple mold, while the inclined hook part is produced separately and assembled later, eliminating the need for complex side molds and reducing overall mold complexity.
Solution Approach 2:
The inclined fastening hook portion is extracted from the integral structure and made into a separate detachable component. This extraction removes the requirement for complex side molds during the molding process, simplifying the mold design while still achieving the desired inclined hook configuration for windshield support.
2Stability of the object's composition
If the mold size increases to accommodate integral fastening hooks, then the cowl top cover can be manufactured as a single piece, but the manufacturing cost increases
Solution Approach 1:
By segmenting the product into a main cover body and separate fastening hooks, the patent enables the use of simpler, smaller molds that are less expensive to fabricate and maintain. The separate production of hooks allows for standardized manufacturing processes that reduce overall production costs.
Solution Approach 2:
The detachable fastening hook design allows the same hook component to be used across different vehicle models and applications. This universality reduces the need for model-specific molds and tooling, thereby lowering manufacturing costs through economies of scale.
3Stability of the object's composition
If separate side molds are installed to form inclined hook parts, then the integral cowl top cover can be manufactured, but the mold fabrication time and cost increase
Solution Approach 1:
The segmentation of the fastening hook into a separate component eliminates the need for time-consuming side mold installations. The main cover can be manufactured using a simple, quick-to-fabricate mold, while the inclined hooks are produced separately using dedicated tooling, significantly reducing overall mold fabrication time.
4Stability of the object's composition
If the mold structure becomes complex, then integral fastening hooks can be formed, but it becomes difficult to modify the mold
Solution Approach 1:
By separating the fastening hook from the main cover, the patent simplifies the main mold structure to a basic injection mold that is easy to modify. Any design changes to the cover body can be made without affecting the hook manufacturing process, providing flexibility for mold modifications and updates.
