Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional foam rubber or gel pad wrist rests are used, then basic cushioning is provided, but they lack innovative geometries and structural elements to provide effective support

Engineering Contradiction:
Improvecushioning effectivenessVSAvoidstructural simplicity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The support structure employs curved surfaces and cylindrical geometry throughout its design. The main support body features a curved top surface that conforms to the natural contour of the wrist, while the legs incorporate cylindrical shapes that provide structural integrity. This curvature principle enhances both the ergonomic comfort and the mechanical strength of the support without adding complex components.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The invention transitions from traditional two-dimensional flat wrist rest pads to a three-dimensional structured support system. The support includes vertical legs that elevate the cushioned surface, creating multiple height levels and spatial dimensions. This dimensional enhancement provides both ergonomic benefits and structural stability simultaneously.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If rigid support structures are used for stability, then structural integrity is maintained, but they prevent natural wrist and arm movement

Engineering Contradiction:
Improvestructural stabilityVSAvoidnatural movement capability
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The support structure incorporates dynamic characteristics by allowing the cushioned top surface to flex and deform in response to user weight and movement, while the cylindrical legs maintain structural stability. This dynamic design enables natural wrist and arm movement while preserving overall structural integrity through the resilient material selection and geometric configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support utilizes flexible cushioning materials covered by a thin outer shell that can deform elastically under load. This flexible shell conforms to the user's wrist shape and allows natural movement, while the underlying cylindrical structural elements provide the necessary stability and support.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of operation

If complex geometries are implemented to enhance comfort, then user experience improves, but manufacturing difficulty increases

Engineering Contradiction:
Improveuser comfortVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The invention achieves enhanced comfort through careful selection and adjustment of geometric parameters such as the radius of the cylindrical legs, the curvature radius of the top surface, and the height of the support structure. By optimizing these parameters within standard manufacturing ranges, the design provides superior ergonomics while remaining compatible with conventional manufacturing processes for molded plastic or metal components.

Inventive Principle:
Principle #35Parameter changes
