Shared Vehicle Compartment Lighting for Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shared vehicles often experience issues with users forgetting objects in storage compartments due to poor visibility and the need for detection sensors, which are costly and require driver diversion to trigger alarms.
Innovation Solution
A system that includes lighting means in the peripheral visual field of the driver, activated when the engine is stopped, to draw attention to storage compartments, eliminating the need for object detection sensors and ensuring the compartment's lid retains its functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detection sensors are installed inside storage compartments to detect objects, then object detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The invention extracts the detection function from the storage compartment interior and relocates it to the vehicle's existing control system. The detection sensor is moved from inside the compartment to detect door opening/closing actions, while the control unit processes this information to trigger appropriate responses, thereby simplifying the overall system architecture
Solution Approach 2:
The invention makes the vehicle's existing door detection sensor serve multiple functions: it detects both door opening/closing actions and indirectly indicates the presence of objects in storage compartments. This multi-functional use eliminates the need for dedicated object detection sensors inside compartments, reducing system complexity
2Reliability
If alarm triggers require door opening action, then driver attention is diverted to the door, but this causes driver distraction and delays alarm effectiveness
Solution Approach 1:
The invention performs preliminary action by providing visual warning (lighting up the compartment) before the driver actually opens the door. When the system detects an object in the storage compartment, it illuminates the compartment area, alerting the driver in advance so they can check the compartment before door opening, preventing forgetful removal
Solution Approach 2:
The invention introduces an intermediary visual warning mechanism (lighting system) between the detection of object presence and the actual alarm trigger. This intermediary provides gentle visual提醒 to the driver, mediating between the detection system and the driver's awareness, reducing abrupt distractions while maintaining reliability
3Reliability
If storage compartments are closed with lids for security, then compartment protection is improved, but visibility of contents and control member accessibility deteriorates
Solution Approach 1:
The invention applies local quality by providing selective lighting only in the storage compartment area when needed, rather than illuminating the entire vehicle interior. The lighting is localized to highlight the compartment and its control member, improving visibility and accessibility without compromising the closed-state security of the compartment
Solution Approach 2:
The lighting system performs preliminary action by illuminating the compartment area before the driver needs to access it. This advance lighting helps the driver locate and access the control member more easily, compensating for the poor visibility caused by the closed lid
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents object forgetting by visually alerting drivers to check storage compartments before exiting, enhancing user experience and reducing lost items without additional sensor costs.
Implementation Method 1
the lighting means comprise a light source and a part made of light-diffusing material and surrounding the opening control member
