Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed support arms are used, then the device structure is simple, but the fit adaptability to various head shapes and sizes is poor
Solution Approach 1:
The support arm incorporates a dynamic portion with adjustable thickness that can be modified in real-time to adapt to different head shapes and sizes. The adjustment mechanism allows the support arm to transition between different configurations, providing customized fit for each user while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent changes the physical parameter of the support arm by adjusting the thickness of the dynamic portion. This parameter modification enables the support arm to accommodate various head dimensions and shapes, improving fit adaptability without requiring a completely complex restructuring of the support arm system.
2Ease of operation
If adjustable mechanisms are added to support arms, then the fit customization is improved, but the device complexity increases
Solution Approach 1:
The support arm is divided into a static portion and a dynamic portion with different functions. The dynamic portion contains the adjustment mechanism and can be independently modified, allowing fit customization without complicating the entire support arm structure. This segmentation enables localized adjustment while maintaining overall structural simplicity.
3Ease of manufacture
If the support arm structure is simplified, then the manufacturing is easier, but the ability to securely fit various head shapes is reduced
Solution Approach 1:
The support arm incorporates a dynamic portion with adjustable thickness that can be modified in real-time to adapt to different head shapes and sizes. The adjustment mechanism allows the support arm to transition between different configurations, providing customized fit for each user while maintaining a relatively simple overall structure.
4Reliability
If fixed thickness support arms are used, then the device structure is simple, but the comfort and stability for various users is poor
Solution Approach 1:
The patent changes the physical parameter of the support arm by adjusting the thickness of the dynamic portion. This parameter modification enables the support arm to accommodate various head dimensions and shapes, improving fit adaptability without requiring a completely complex restructuring of the support arm system.
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
The adjustable arm tips provide a secure, customizable fit that reduces the risk of drop events and improves comfort by dynamically adjusting to the user's head shape, ensuring stable support for the device's weight and sensitive components.
Implementation Method 1
The adjustment mechanism can include a moveable member, a first magnet engageable with the movable member in a first state, and a second magnet engageable with the movable member in a second state.
Implementation Method 2
The movable section can include a deformable wire.
Implementation Method 3
The variable volume bladder can be adjusted using at least one of pneumatics or hydraulics.
