Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional arm rest pads with limited range of motion are used, then the structure is simple and stable, but friction increases and comfort decreases leading to musculoskeletal disorders

Engineering Contradiction:

ImprovecomfortVSAvoidstructure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The arm rest pad is divided into multiple segments including a base, a pivot mechanism, and a movable padding section. This segmentation allows independent movement of each component, enabling the pad to adapt to various arm positions while maintaining structural stability through the modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The arm rest pad incorporates dynamic elements such as a pivot mechanism with rotational joints and a movable padding section that can adjust its position. This dynamic design allows the pad to move with the user's arm in multiple directions, reducing friction and discomfort while maintaining overall structural integrity through controlled movement mechanisms.

AI summary

The present invention provides a unique, compact, soft-cushioned, multi-directional, 360° gliding arm rest pad device which effectively eliminates forearm-to-pad friction during movement of a user's arm in any direction when operating a device, such as a computer mouse, a joystick or any other equipment that may place stress and strain on one's hands, arms, and elbows. The multi-directional gliding arm rest pad device allows free movement of a user's forearm to glide multi-directionally with minimal tension resistance, so that shoulder strain is substantially reduced, development of bursitis, carpal tunnel syndrome, cubital tunnel syndrome, and elbow pain is greatly diminished, and a user's functional work performance duration time is extended due to reduction of hand and arm fatigue afforded by the smooth and effortless directional movement of the arm rest pad.
