Vehicle Seat Emblem Bonding Through Selective Coating Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Attaching emblems to vehicle seats is challenging due to the protective coating layer, which hinders the attachment process while providing protection against damage.
Innovation Solution
The method involves removing the coating layer to match the emblem's shape, aligning the emblem with the exposed area, and using a high-frequency fusion method with a mold unit to attach the emblem, applying a high-frequency current for bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a coating layer is formed on the vehicle seat to protect against damage, then protection against contamination and damage is improved, but attachment of the emblem becomes difficult
Solution Approach 1:
The coating layer is removed in advance at the emblem attachment position before the emblem attachment process. This preliminary removal creates a clean bonding surface that allows the emblem to be securely attached to the seat base material, resolving the contradiction between maintaining protective coating and enabling emblem attachment.
Solution Approach 2:
The coating layer is selectively removed only at the specific region where the emblem will be attached, rather than removing the entire coating layer. This segmented approach maintains the protective coating on the rest of the seat while creating a localized attachment area, thus preserving both protection and attachment capability.
2Ease of manufacture
If the coating layer is removed to attach the emblem, then ease of emblem attachment is improved, but protection against damage is reduced
Solution Approach 1:
The coating layer is removed only at the specific emblem attachment region rather than the entire seat surface. This localized removal provides adequate access for emblem attachment while preserving the protective coating on the surrounding areas, thus maintaining overall protection while enabling manufacturing.
3Manufacturing precision
If a laser is used to remove the coating layer, then manufacturing precision is improved, but use of energy increases
Solution Approach 1:
The laser is applied with localized energy delivery focused precisely at the emblem attachment position. This concentrated local treatment achieves the required precision for coating removal while minimizing overall energy consumption by treating only the necessary small area rather than the entire seat surface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method securely attaches the emblem to the vehicle seat, enhancing design aesthetics while preventing damage to the seat from contamination and other factors.
Implementation Method 1
attaching the emblem to the seat by pressing the emblem using a mold unit and applying a high-frequency current
Implementation Method 2
The removing of the coating layer may be performed by irradiating the seat with a laser
