Electronic Key Holder With Synchronized Audio and Glove Box Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted apparatuses for accommodating electronic keys in shared vehicles face usability issues due to inadequate lighting and guidance, particularly in low-light conditions, and require unnecessary preparation by users unfamiliar with the handling procedures.
Innovation Solution
The apparatus incorporates a speaker for audio guidance and a lighting control unit to provide illumination synchronized with audio instructions, ensuring users can accurately operate the apparatus and handle the electronic key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle-mounted apparatus is installed in a glove box, then the apparatus can be securely mounted, but brightness necessary for user operation cannot be ensured in low-light conditions
Solution Approach 1:
The lighting control unit activates illumination before the user needs to perform operations, providing advance lighting in the glove box area. This preliminary lighting action ensures that the user can see and operate the apparatus from the moment they open the glove box, without needing to adapt to darkness first.
Solution Approach 2:
The light emitting unit acts as an intermediary element between the apparatus and the user's visual system. It provides the necessary illumination that mediates the interaction between the user and the apparatus components, enabling visual perception in the confined glove box space.
2Loss of information
If users are provided with detailed leaflets and website instructions, then complete handling procedures can be explained, but not all users will learn and operate the apparatus correctly
Solution Approach 1:
The audio control unit provides real-time feedback to the user during operations. When the user performs actions like opening the apparatus or taking/returning keys, the system responds with appropriate audio guidance, confirming correct operation or guiding correction of mistakes. This feedback loop ensures users receive immediate information about their actions without needing to recall detailed instructions.
Solution Approach 2:
The apparatus provides its own operational guidance through integrated audio and lighting systems, eliminating the need for users to separately study external materials. The system serves itself by automatically explaining procedures and confirming operations, making the information delivery self-contained and unavoidable during the interaction.
3Loss of information
If audio guidance is emitted to guide user operations, then users can be notified of operations to be performed, but users still need adequate lighting to see and perform the operations
Solution Approach 1:
The patent combines multiple guidance functions into a single integrated system. The audio control unit and lighting control unit work together as a unified guidance mechanism, where audio provides verbal instructions while lighting provides visual illumination. This merging ensures that both information delivery and visual capability are addressed simultaneously, creating a comprehensive guidance system that overcomes the limitations of either approach alone.
