Concealed Rooflight Lifting Assembly for Taxi Roof Sign Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cruise taxis cannot integrate effectively with online ride-hailing taxis due to differences in appearance and service standards, leading to resource waste and suboptimal user experience.
Innovation Solution
A concealed roof light system comprising a light box assembly connected to a lifting assembly, which allows the roof light to be concealed within the vehicle body, providing a unified appearance with online ride-hailing vehicles when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a rooflight is integrated into a vehicle body, then natural light enters the vehicle interior and ventilation is improved, but water can penetrate through the rooflight and damage the vehicle body
Solution Approach 1:
The cover element is designed to nest over the rooflight assembly, with the integrated water deflection layer forming an outer protective shell that encapsulates the rooflight. This nested structure allows the cover element to protect the rooflight from water penetration while maintaining the rooflight's light transmission function when needed.
Solution Approach 2:
The water deflection layer acts as an intermediary between the external environment (rain, water) and the rooflight assembly. This intermediate layer deflects water away from the rooflight sealing, preventing water penetration while allowing the rooflight to continue providing natural light and ventilation.
2Productivity
If a rooflight is integrated into a vehicle body, then natural ventilation is improved, but the sealing becomes complex and water penetration risk increases
Solution Approach 1:
The water deflection function is extracted from the rooflight sealing system itself and implemented as a separate, integrated layer within the cover element. This extraction simplifies the rooflight sealing by removing the need for complex water deflection mechanisms, while still providing effective water protection and maintaining ventilation capabilities.
3Object-affected harmful factors
If a cover element is provided to protect the rooflight, then water penetration is prevented, but the rooflight cannot be opened for ventilation
Solution Approach 1:
The cover element is designed with dynamic characteristics, allowing it to be selectively positioned between a closed protective state and an open ventilative state. The integrated water deflection layer remains effective in both states, providing water protection when closed while allowing full ventilation access when opened.
4Temperature
If the vehicle body is heated or cooled, then thermal comfort is improved, but energy consumption increases
Solution Approach 1:
The rooflight assembly incorporates materials and design features that change their thermal parameters in response to environmental conditions. The integrated water deflection layer and sealing system are designed to maintain thermal efficiency across different temperature ranges, reducing the energy required for heating or cooling the vehicle interior.
