Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vibrators are integrated into the display device for tactile feedback functionality, then user interaction experience is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent merges the vibrator assembly with the display panel assembly by providing a vibration generating module that includes vibrators mounted on a first substrate, which is then integrated with the display panel. This combining approach reduces overall device complexity and streamlines manufacturing processes while maintaining tactile feedback functionality.
Solution Approach 2:
The first substrate serves multiple functions: it acts as a mounting platform for the vibrators, provides structural support for the vibration generating module, and facilitates integration with the display panel. This multi-functionality reduces the need for additional components and simplifies the overall device structure.
2Area of stationary object
If multiple vibrators are arranged along the edge of the substrate, then tactile feedback coverage is improved, but manufacturing precision requirements increase
Solution Approach 1:
The vibration generating module is segmented into multiple independent vibrators arranged along the edge of the first substrate. Each vibrator can be independently positioned and tested, which simplifies the manufacturing process and reduces the overall precision requirements compared to a monolithic vibration system.
Solution Approach 2:
The vibrators are pre-mounted on the first substrate to form a complete vibration generating module before integration with the display panel. This preliminary assembly allows for easier positioning and testing, reducing the precision requirements during final device assembly.
3Reliability
If vibrators are tested before attachment to the display panel, then yield is improved, but manufacturing process time increases
Solution Approach 1:
The vibrators are tested for functionality before being mounted on the first substrate to form the vibration generating module. This preliminary testing identifies defective vibrators early in the manufacturing process, improving overall yield by preventing defective units from proceeding to later assembly stages.
Solution Approach 2:
The manufacturing process is segmented into distinct stages: vibrator testing, vibrator mounting on substrate, module assembly, and final device integration. This segmentation allows testing to be performed efficiently on individual components rather than on complete assemblies, reducing the time penalty associated with testing.
