Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air vent systems require exposed components for controlling wind direction, leading to increased unexposed components and design limitations in cockpit design diversification.
Innovation Solution
A vehicle air vent system with a garnish-mounted vent module that includes a nozzle, rotating wings, and a driving assembly, allowing for indirect control of wind direction without exposing control components, utilizing a motor, gear unit, and link arms to rotate the wings and guide air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the air vent components are hidden behind the garnish to improve design aesthetics, then the design versatility is improved, but the control mechanism complexity increases due to indirect manipulation requirements
Solution Approach 1:
The patent combines multiple control functions into a single integrated mechanism. The first wing and second wing are connected through a common rotation driving assembly, allowing both wings to be controlled indirectly through a single input from the control unit. This merging of control functions reduces the overall system complexity while maintaining the hidden design behind the garnish.
Solution Approach 2:
The patent introduces a rotation driving assembly as an intermediary mechanism between the control unit and the wings. This intermediary converts the control signals into coordinated rotation movements of the first and second wings, enabling indirect manipulation while maintaining precise control. The intermediary mechanism allows the control unit to operate hidden components without direct exposure.
2Shape
If a rotation driving assembly is introduced to enable indirect control, then the design aesthetics are improved by hiding components, but the device complexity increases
Solution Approach 1:
The rotation driving assembly performs multiple functions simultaneously: it controls both the first wing and second wing, enables indirect manipulation, and maintains coordinated movement between components. By making this single mechanism multi-functional, the patent reduces the need for separate control systems for each wing, thereby limiting the increase in device complexity while achieving the desired aesthetic design.
3Adaptability or versatility
If the nozzle and wings are made rotatable for indirect control, then the wind direction control flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic control by making the nozzle and wings rotatable rather than fixed. The first wing and second wing can rotate independently to adjust wind direction, providing flexibility in air flow control. The dynamics principle allows the system to adapt to different ventilation requirements while using a unified rotation driving assembly, balancing flexibility with controlled complexity.
