Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vibration modules are used, then vibration feedback function is achieved, but the thickness and volume of the touch pad increase
Solution Approach 1:
The patent integrates multiple components into a unified structure where the housing serves both as the vibration transmission path and as the mounting structure for the coil and magnetic element. The circuit board is integrated into the housing, eliminating the need for separate mounting brackets and reducing overall thickness while maintaining vibration feedback functionality.
Solution Approach 2:
The housing performs multiple functions simultaneously: it serves as the structural frame, the vibration transmission medium, the mounting platform for electromagnetic components, and the protective enclosure. This multi-functionality reduces the number of separate components needed, thereby reducing overall thickness.
2Reliability
If conventional vibration modules with multiple components are used, then vibration function is achieved, but the manufacturing process becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent combines the housing, coil assembly, magnetic element mounting, and circuit board into a single integrated structure. This merging of components simplifies the bill of materials, reduces assembly steps, and lowers manufacturing complexity while maintaining the required vibration function.
Solution Approach 2:
The design segments the vibration module into functional zones within a single housing structure: the coil mounting area, magnetic element positioning area, and vibration transmission path. This functional segmentation allows for simplified manufacturing of each zone while maintaining overall system functionality.
3Reliability
If conventional vibration modules with multiple components are assembled, then vibration assembly is completed, but assembly errors increase and defective products are produced
Solution Approach 1:
By integrating the housing and its mounting structures into a single piece, the patent eliminates multiple assembly operations and reduces the opportunities for assembly errors. The integrated design ensures proper alignment and spacing of components without requiring precision assembly of multiple separate parts.
Solution Approach 2:
The housing is pre-designed with integrated mounting features, positioning structures, and alignment guides that ensure correct component placement during assembly. This preliminary structuring of the housing reduces the skill level required for assembly and minimizes assembly errors.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a thinner and more reliable vibration module with simplified assembly and manufacturing, providing efficient vibration transmission and reduced manufacturing costs.
Implementation Method 1
When the magnetic element senses the coil layer inside the module, the magnetic element vibrates
Implementation Method 2
the elastic structure of the housing is directly connected with the magnetic element to provide the efficacy of supporting the magnetic element and transmitting the vibration energy
Implementation Method 3
Under the influence of the magnetic force or in the power on status, the vibration element will produce continuous and repeated displacement, rotation or deformation to result in a vibration effect

AI summary
A vibration module is installed in a touch plate. The vibration module includes a housing, a magnetic element, a coil layer and a base plate. The housing includes an accommodation space and an elastic structure. The magnetic element and the coil layer are aligned with each other and disposed within the accommodation space. The base plate is connected with the housing. In addition, the magnetic element and the coil layer are sealed in the accommodation space. The base plate is connected with the housing to seal the magnetic element and the coil layer in the accommodation space. The elastic structure is extended in the direction toward the accommodation space and connected with the magnetic element. The magnetic element is pushed to be close to the coil layer by the elastic structure. When the coil layer is electrically conducted, the magnetic element senses the coil layer and vibrates.
