Solution Overview

Problem

Existing maneuver elements for mobile devices lack clear indication of functionality, especially 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 trilobal design featuring a dome-shaped button with a circumferential groove, a ring with distinct coloration, and an indicator element with a red-colored cup appendix, combined with a pull-and-push mechanism using a rotor and stator with inclined planes and guidance teeth, allowing easy identification of the lock status and operation with minimal strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a dome structure with cup button is used to indicate lock status, then remote identification of lock status is ensured, but the signal is not always easy to read and the push-traction movement system becomes complex

Engineering Contradiction:
Improvelock status indication visibilityVSAvoidpush-traction movement system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies color changes by providing the cup button with a lateral surface showing different coloring from the grip element (e.g., red color). This color differentiation provides immediate visual indication of lock status without requiring complex mechanical signaling systems, directly resolving the contradiction between visibility and complexity

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent segments the indication system into distinct visual components: the grip element and the separately colored cup button. This segmentation allows the status indication function to be isolated and simplified, making the system easier to understand and operate while maintaining clear visual feedback

Inventive Principle:
Principle #1Segmentation

2Reliability

If traditional maneuver elements are used, then basic locking function is provided, but they fail to meet ADA standards requiring activation with minimal strength (at most 20.2 N)

Engineering Contradiction:
ImproveADA complianceVSAvoidactivation strength requirement
Core Design Contradiction:
ReliabilityVSForce

Solution Approach 1:

The patent employs spheroidality by designing the grip element with a curved, dome-shaped button surface. This curved geometry distributes the activation force more effectively across the pressing surface, reducing the peak force required to activate the locking mechanism and enabling compliance with ADA strength limitations

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent incorporates dynamics through the spring means that enable the cup button to move between pressed and unpressed positions. This dynamic mechanism allows the system to respond to minimal input force while maintaining reliable locking engagement, meeting ADA requirements for easy activation

Inventive Principle:
Principle #15Dynamics

3Reliability

If safety pressure means with protruding pins and holes are used, then rotation prevention is achieved, but the device complexity increases and operation becomes less intuitive

Engineering Contradiction:
Improverotation preventionVSAvoidoperation intuitiveness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent merges multiple functions into the grip element: it serves as both the operational handle for activating the locking mechanism and the visual indicator through the colored cup button. This consolidation simplifies the user interface while maintaining reliable rotation prevention through the underlying pin-and-hole engagement mechanism

Inventive Principle:
Principle #5Merging (Combining)
