Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing maneuver elements for mobile devices lack clear indication of functionality, particularly in the locked position, and can be complex to operate, failing to meet ADA standards for accessible design and requiring excessive strength for activation.
Innovation Solution
A maneuver element with a button system featuring a dome-shaped safety mechanism, colored indicators, and a rotor-stator mechanism for easy activation and remote status identification, allowing operation with minimal strength and compliance with ADA standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a push-pull system is used for the grip element movement, then the safety means can be activated, but the operation becomes complex and requires excessive strength
Solution Approach 1:
The patent replaces the complex push-pull mechanical system with a rotor-stator mechanism that uses rotational motion instead of linear push-pull movement. The rotor rotates within the stator to engage and disengage locking pins, eliminating the need for complex push-pull linkages and reducing the activation force required while maintaining safety functionality.
Solution Approach 2:
The grip element is designed to rotate dynamically within its housing rather than moving linearly through a push-pull system. This rotational movement allows the grip to engage and disengage locking pins through simple rotation, making the operation easier and requiring less strength while maintaining reliable safety activation.
2Loss of information
If the lock status is indicated only when locked, then the device functionality can be identified, but the indication is not always easy to read and is not visible in rest position
Solution Approach 1:
The patent uses color-coded indicators that are visible in both locked and unlocked positions. Different colors indicate different operational states, allowing operators to immediately identify the current status without requiring close inspection or specific lighting conditions. The color indicators are integrated into the grip element and rotor assembly, ensuring continuous visibility.
Solution Approach 2:
The indicator system is designed to show the operational status in advance and continuously, rather than only when the lock is engaged. The color-coded indicators are positioned to be visible from a distance and in all operational positions, allowing operators to know the current state before attempting any operation.
3Device complexity
If the maneuver element follows traditional design, then the structure is simple, but it does not comply with ADA standards for accessible design
Solution Approach 1:
The maneuver element uses rotational movement instead of linear push-pull motion, making it accessible to operators with limited hand strength or dexterity. The rotation can be performed with a single hand and requires minimal force, complying with ADA standards while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent changes the activation parameter from linear force (push-pull) to rotational torque, which is easier to apply for operators with limited hand strength. The rotor-stator mechanism allows activation with minimal rotational force, meeting ADA accessibility requirements while keeping the structural design straightforward.
