Solution Overview

Problem

Existing embedding apparatuses lack a wrist rest or hand-rest component that is adjustable in thickness to accommodate different operators' preferences, leading to variability in operability and increased hand fatigue during precise embedding operations.

Innovation Solution

A detachable wrist rest with an adjustable attachment mechanism, including engagement pieces and a pressure-sensitive adhesive surface, that can be easily attached and detached from the embedding apparatus, allowing for customizable thickness and enhanced cushioning properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed hand-rest part or wrist-rest part is provided on the embedding apparatus, then the operator's hand is supported to reduce fatigue, but the operability cannot be optimized for all operators since hand-rest preferences vary by operator

Engineering Contradiction:
ImproveoperabilityVSAvoidadaptability to different operators
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The wrist rest is designed as a detachable component that can be attached and removed from the embedding apparatus. This dynamic configuration allows the thickness and presence of the wrist rest to be adjusted according to each operator's preference, resolving the contradiction between providing fixed support and adapting to varying operator needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The hand-rest function is segmented into a detachable wrist rest portion that can be separately attached to the embedding apparatus. This segmentation allows operators to attach or detach the wrist rest based on their individual comfort requirements, enabling customization without affecting the core apparatus.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a wrist rest is permanently integrated into the embedding apparatus, then hand support is consistently available, but the thickness cannot be adjusted to accommodate different operator preferences

Engineering Contradiction:
Improvehand support consistencyVSAvoidthickness adjustability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The wrist rest transitions from a static, permanently integrated component to a dynamic, detachable component. This allows the thickness and presence of the wrist rest to be flexibly adjusted according to operator preference while maintaining consistent availability when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The wrist rest is separated from the main embedding apparatus as an independent detachable component. This segmentation enables operators to attach or detach the wrist rest based on their specific needs, providing both consistency when attached and adjustability through optional removal.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple wrist rest options with different thicknesses are provided, then operator preferences can be accommodated, but the device complexity increases

Engineering Contradiction:
Improvethickness customizationVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wrist rest functionality is segmented into a single detachable component that can be attached or removed based on operator preference. This approach provides thickness customization without the complexity of managing multiple different wrist rest components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A single detachable wrist rest component provides dynamic adaptability through attachment and detachment rather than through multiple static components with different thicknesses. This reduces device complexity while maintaining the ability to accommodate operator preferences.

Inventive Principle:
Principle #15Dynamics
