Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If shift stage information is displayed using visual indicators or auditory warnings, then drivers with normal sensory abilities can easily perceive shift stages, but drivers with hearing or visual impairments cannot perceive the shift stages
Solution Approach 1:
The patent introduces braille display modules and bone conduction earphones as intermediary devices that translate visual and auditory shift stage information into tactile forms. The braille modules convert shift stage data into raised dot patterns that visually impaired drivers can feel, while bone conduction earphones transmit vibrations through the skull to convey information to hearing impaired drivers, serving as mediators between the vehicle's electronic shift system and drivers with sensory impairments
Solution Approach 2:
The patent replaces traditional visual and auditory information delivery mechanisms with tactile mechanical feedback systems. Braille display modules use mechanical actuators to raise and lower dots, creating tactile representations of shift stages. Bone conduction devices use mechanical vibrations transmitted through the skull bones to convey information, substituting the acoustic air-conduction path with a direct mechanical transmission path that bypasses the ear canal and eardrum
2Adaptability or versatility
If multiple output devices (braille module, bone conduction earphones, cluster) are used to provide shift stage information, then accessibility for drivers with disabilities is improved, but device complexity increases
Solution Approach 1:
The patent designs the shift information system with multi-functional capability by integrating multiple output devices (braille display modules, bone conduction earphones, and cluster displays) that can serve different user needs. The same shift stage information from the vehicle's controller is simultaneously routed to multiple output channels, allowing the system to adapt to different driver requirements without requiring separate independent systems for each type of driver
Solution Approach 2:
The patent divides the shift information delivery function into separate modular components: braille display modules for tactile visual information, bone conduction earphones for auditory information, and cluster displays for traditional visual information. Each module handles a specific type of information delivery, allowing independent optimization and maintenance of each component while reducing the overall system complexity through functional segmentation
