Fin for register
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fin designs for air conditioning registers in vehicles lack a secure method to firmly attach the mounting member to the fin body, particularly at the downstream edge, which affects the durability and stability of the assembly.
Innovation Solution
A fin design featuring a mounting member with a curved shape that covers the downstream edge of the fin body, where the edge includes a recessed part filled with adhesive to securely attach the mounting member, enhancing the bonding between the fin body and the mounting member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting member is mounted to the fin body using conventional methods (e.g., ultrasonic welding with protrusion and insertion hole), then the assembly can be completed with standard processes, but the mounting member may not be firmly fixed and may detach or displace
Solution Approach 1:
The first recessed part is formed in advance on the downstream side edge part of the fin body before mounting the mounting member. This preliminary preparation of the recessed part allows the adhesive to be properly positioned and maximize bonding surface area, ensuring firm fixation of the mounting member before any operational stresses are applied.
Solution Approach 2:
An adhesive is introduced as an intermediary substance between the fin body and the mounting member. The adhesive fills the first recessed part and creates a strong bonding interface, mediating the connection between the two components to prevent detachment and position displacement that would occur with mechanical joining methods alone.
2Reliability
If the downstream side edge part is modified with a recessed part and adhesive filling, then the mounting member is firmly fixed, but the manufacturing process becomes more complex
Solution Approach 1:
The first recessed part is formed on the downstream side edge part before the mounting member is attached. This preliminary formation of the recessed part simplifies the overall manufacturing process by preparing the bonding surface in advance, allowing for controlled adhesive application and ensuring proper positioning without requiring complex assembly operations.
Solution Approach 2:
The conventional mechanical fixing method (ultrasonic welding with protrusion and insertion hole) is replaced with a chemical bonding method using adhesive. This substitution eliminates the need for complex mechanical interlocking structures and ultrasonic welding equipment, simplifying the manufacturing process while achieving reliable attachment.
3Stability of the object's composition
If adhesive is used to fill the recessed part for mounting, then position displacement is prevented, but additional materials and steps are required
Solution Approach 1:
The adhesive serves as an intermediary material that fills the first recessed part and bonds the mounting member to the fin body. This intermediary substance prevents position displacement by creating a strong bonding interface while maintaining a simple assembly structure without requiring additional mechanical positioning features or complex fastening mechanisms.

Function Achieved in This Case
The adhesive-filled recessed part provides a strong and stable attachment, preventing detachment and position displacement of the mounting member, thereby improving the structural integrity and appearance of the fin assembly.
Implementation Method 1
the downstream side edge part and the mounting part are fixed to each other by an adhesive filled in the first recessed part

AI summary
Provided is a fin for register that can firmly fix a mounting member to a fin body. A horizontal fin includes a plate-shaped fin body and a mounting member mounted to a downstream side edge part of the fin body. The mounting member has a curved shape to cover the downstream side edge part of the fin body. The downstream side edge part includes a first recessed part at a tip part on a front side in a longitudinal direction. The first recessed part is formed by recessing the tip part of the downstream side edge part. The downstream side edge part and the mounting member are fixed to each other by an adhesive filled in the first recessed part.
