Solution Overview
Problem
Existing tools for installing vehicle door seals are ergonomically poor, generate excessive noise and vibrations, and fail to meet modern noise pollution and vibration standards, making them uncomfortable for operators to use in the automotive industry.
Innovation Solution
A device with a vibration generator and elastic connection elements between the main body and grip handle, using polyurethane materials to dampen and filter out low and high-frequency vibrations, and sound insulation to reduce noise, allowing for a more ergonomic and comfortable handling experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pneumatic vibrating tool is used to install sealing gaskets, then the sealing gasket can be compressed onto the support, but the tool generates excessive noise and vibrations that are harmful to operators
Solution Approach 1:
A damping element is introduced as an intermediary component between the vibration generator and the handle. This damping element absorbs and dissipates vibrations generated by the pneumatic mechanism, preventing them from being transmitted to the handle and ultimately to the operator's hand, while still allowing the vibration generator to effectively compress the sealing gasket
Solution Approach 2:
The damping element functions as a flexible component that selectively absorbs vibrations. Its flexible structure allows it to deform under vibration forces, converting mechanical vibration energy into heat energy through internal friction, thereby reducing the transmission of harmful vibrations to the handle
2Device complexity
If the main body is gripped directly by the handle, then the tool structure is simple, but the operator feels many vibrations and the tool is difficult to handle
Solution Approach 1:
The tool is segmented into distinct functional components: the vibration generator (main body), the damping element, and the handle. This segmentation allows the vibration-generating function to be separated from the grip function, enabling the handle to be designed for ergonomic comfort while the main body maintains its vibration-generating capability
3Productivity
If a tool with translational back-and-forth movement is used, then the sealing gasket can be installed, but numerous vibrations are generated during operation
Solution Approach 1:
The damping element converts the harmful vibration energy generated by the translational back-and-forth movement into beneficial thermal energy through internal friction. By transforming the harmful mechanical vibrations into heat, the damping element eliminates the negative effects while preserving the useful compression function

Implementation Method 1
elastic connecting elements between the main body and the gripping handle configured to limit the propagation, in the gripping handle, of the vibrations generated by the translational back-and-forth movement
Implementation Method 2
The Applicant submits that such a device is already known from document JP 2007 261356. According to the operation described above, the operator directs this tool so that the contact surface of the shoe presses against the sealing gasket and compresses said gasket against the support.
