Ergonomic Tablet Holder with Adjustable Counterweight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer device holders, such as those for tablets and laptops, often fail to provide ergonomic comfort and stability, as they do not adequately adjust to user-specific typing pressures, leading to unintentional device movement during use.
Innovation Solution
An adjustable ergonomic holder assembly with a rotatable display support and a counterweight assembly that adjusts the center of gravity to provide customizable force feedback, allowing users to set the optimal angular orientation and resistance based on their typing style.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tablet is retained on a movable mounting feature that holds the tablet at a tipped angle, then the user can achieve better ergonomic comfort, but the mounting feature must be able to resist the user's typing pressure to avoid inadvertently moving the tablet during use
Solution Approach 1:
The patent employs a counterweight mechanism that balances the tablet at a tipped angle, allowing ergonomic positioning while compensating for typing forces. The counterweight creates a balancing force that offsets the user's typing pressure, preventing inadvertent movement of the tablet while maintaining the ergonomic tipped orientation.
Solution Approach 2:
The mounting feature is designed with dynamic adjustment capabilities, allowing it to adapt to different typing pressures and user preferences. The system can dynamically adjust the balance point and resistance characteristics to accommodate varying user forces while maintaining stable ergonomic positioning.
2Ease of operation
If the tablet is retained on a movable mounting feature, then the tablet can be positioned at an ergonomic angle, but the user must change his or her typing pressure to prevent the tablet from unintentionally moving
Solution Approach 1:
The counterweight mechanism automatically self-adjusts to balance the tablet against typing forces without requiring user intervention. The system self-regulates the balancing force based on the tablet's position and the forces applied, eliminating the need for users to consciously adjust their typing pressure to prevent movement.
Solution Approach 2:
The mounting feature incorporates force feedback mechanisms that respond to user typing pressure in real-time. The counterweight system provides resistive feedback that matches the user's input forces, creating a balanced interaction that maintains stable positioning while allowing natural typing pressure variations.
3Productivity
If multiple users share a single tablet holder, then device utilization is maximized, but each user has unique typing pressure requirements that cannot be simultaneously satisfied
Solution Approach 1:
The holder incorporates dynamic adjustment mechanisms that allow multiple users to quickly customize the counterweight and angle settings according to their individual typing pressures and preferences. The system can be rapidly reconfigured between users while maintaining optimal performance for each individual.
Solution Approach 2:
The system allows adjustment of key parameters such as counterweight position, tipping angle, and resistance characteristics to accommodate different user requirements. By enabling parameter changes, the holder can be optimized for each user's unique typing style while maintaining high device utilization across multiple users.
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 holder assembly ensures ergonomic comfort and stability by allowing users to adjust the device's orientation and resistance to match their typing pressure, preventing unintentional movement and enhancing usability for multiple users with varying typing habits.
Implementation Method 1
An adjustable counterweight assembly is connected to the support structure and is configured to move the center of gravity of the assembly toward or away from the tablet, so as to increase or decrease the force feedback provided to a user when typing or otherwise pressing on the tablet
Implementation Method 2
The display support and the computer device are rotatable as a unit about the axis of rotation in response to a user pressing against an input portion of the computer device at a location spaced apart from the axis of rotation
Data Source
AI summary
An adjustable holder assembly is disclosed that has a mounting structure and a display support with a center of gravity and being rotatably coupled to the mounting structure for rotation about an axis of rotation. The display support has a support structure and an adjustable counterweight assembly with a counterweight and an adjustment mechanism connected to the counterweight. The counterweight is spaced apart from display support's axis of rotation. The adjustment mechanism is adjustable to move the counterweight in a direction normal to the axis of rotation to move the center of gravity toward or away from the support structure. The adjustable counterweight is configured to provide a force feedback to a user pressing on an input portion of the computer tablet by moving the center of gravity toward or away from the support structure.
