Touch Sensor Coupling Structure for Sliding Door Flange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch sensor coupling structures for automobile sliding doors fail to systematically follow the curved shape of the flange, leading to instability and increased complexity in manufacturing, with prior solutions either requiring additional adhesive processes or being prone to shifting under shocks.
Innovation Solution
A touch sensor coupling structure featuring a raising member with continuous, integral blocks and grooves, formed by die molding, which rises outwardly from the inner-cabin side wall to accommodate the flange's curve, ensuring stable attachment and reduced manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the touch sensor is pressed toward the exterior of the automobile to follow the curve of the flange, then the touch sensor can be attached to the curved flange, but the installation base member is crushed and the opening narrows, requiring additional strengthening measures
Solution Approach 1:
The installation base member is divided into a curved portion and a straight portion. The curved portion specifically follows the curve of the flange, while the straight portion maintains structural strength. This segmentation allows the touch sensor to follow the curved flange without crushing the entire installation base member, eliminating the need for additional strengthening measures like rubber plates.
Solution Approach 2:
Only the curved portion of the installation base member is designed to be flexible and follow the flange curve, while the straight portion maintains rigidity for structural support. This local differentiation of properties allows the system to simultaneously achieve curve following and structural strength without compromise.
2Strength
If crushing measures or adhesive plates are added to strengthen the installation base member, then the structural strength is improved, but the number of processes increases and operations become complicated
Solution Approach 1:
The curved and straight portions are integrated into a single installation base member formed by one extrusion molding process. This merging eliminates the need for separate strengthening components like rubber plates and their associated adhesive processes, reducing manufacturing complexity while maintaining structural strength.
Solution Approach 2:
The installation base member's own structure is designed to provide both curve following and structural strength through its integrated curved and straight portions. This self-service design eliminates the need for additional external strengthening components and processes, simplifying manufacturing.
3Strength
If the installation base member is crushed to narrow the opening, then the local strength is increased, but the appearance is differentiated and becomes non-uniform
Solution Approach 1:
The installation base member is segmented into curved and straight portions with distinct functional roles. The curved portion naturally follows the flange curve without crushing, maintaining appearance uniformity, while the straight portion provides structural strength. This segmentation avoids the appearance degradation caused by crushing.
4Strength
If a rubber plate is adhered to strengthen the installation base member, then the structural strength is improved, but the adhesive may spot products and the rubber plate is hard to arrange on a fixed position
Solution Approach 1:
The strengthening function is merged into the installation base member itself through its integrated curved and straight portions. This eliminates the need for separate rubber plates and adhesive processes, removing all associated assembly difficulties including adhesive spotting and positioning errors.
Solution Approach 2:
The installation base member provides its own structural strengthening through its designed curved and straight portions, eliminating the need for external adhesive plates. This self-service approach completely avoids assembly issues related to adhesive application and component positioning.

AI summary
A part of a touch sensor, which couples to a curve of a flange, includes a raising member. The curve of the flange is on a belt line of a sliding door. The raising member rises outwardly toward an exterior of the automobile from an inner-cabin side wall of the touch sensor. A space is formed between the raising member and an outer-cabin side wall for the flange to be inserted into the space. The raising member includes a plurality of blocks. The plurality of blocks exist along an upper and lower direction of the automobile body.
