Bicycle Display Expansion Using Pneumatic Support Without Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclists face safety risks and disrupted riding experiences when using mobile devices to view information while riding, as it diverts attention and wastes time.
Innovation Solution
A display system integrated into a vehicle, such as a bicycle, featuring a pressure control unit that switches a flexible display unit between expanded and contracted states using pressure generated by a pedal component, allowing users to easily open and close the display without a bracket, using a pressure generating component, isolating component, and pressure adjusting component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a flexible display screen is used without a bracket, then the device complexity is reduced and ease of operation is improved, but the display unit cannot be stably supported or positioned
Solution Approach 1:
The patent uses a pressure control unit with a pressure generating component to inflate or deflate a flexible air mattress, which in turn supports or retracts the display unit. This pneumatic mechanism replaces the need for a traditional bracket structure, reducing device complexity while providing stable support when the air mattress is inflated.
Solution Approach 2:
The patent changes the physical state of the air mattress from inflated to deflated to control the display unit's position. By adjusting the pressure parameter of the air mattress, the display unit can be stably supported in an extended state or retracted into a compact state, maintaining stability while eliminating the bracket.
2Ease of operation
If the display unit is always extended, then information viewing is convenient, but the riding experience is disrupted and safety is compromised
Solution Approach 1:
The patent makes the display unit dynamically adjustable between extended and retracted states through pneumatic control. The display unit can be extended when the rider needs to view information and retracted when safe riding is prioritized, allowing the system to adapt to different operational requirements and maintain both convenience and safety.
Solution Approach 2:
The pressure control unit allows the rider to easily control the display unit's extension and retraction through simple pressure adjustments. The system serves itself by automatically adjusting the display unit's state based on rider needs, improving safety by reducing the need for manual intervention while riding.
3Stability of the object's composition
If a traditional fixed display is used, then the display is stable and reliable, but it cannot be easily stored or transported
Solution Approach 1:
The patent employs a dynamically adjustable display unit that can transition between extended and retracted states. When extended, the display provides stable viewing; when retracted, the display unit folds back along the bicycle frame, enabling easy storage and transport without compromising stability during use.
Solution Approach 2:
The display unit is designed to nest along the bicycle frame when retracted. The flexible display screen and support structure fold back and integrate with the frame structure, allowing the display to be stored compactly without requiring separate storage space, thus improving adaptability for transport while maintaining stability during operation.
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
Enables cyclists to safely and conveniently view information without the need for external devices, improving riding experience by allowing seamless control of the display without additional support or installation, enhancing safety and usability.
Implementation Method 1
the pressure control unit produces pressure which acts to blow up the elastic air mattress, the elastic air mattress brings the flexible display screen to be converted from a second state into a first state
Implementation Method 2
the pressure control unit releases pressure, the elastic air mattress contracts, and brings the flexible display screen to be converted from the first state into the second state
