Solution Overview

Problem

The challenge in designing small-sized computing devices is to integrate a user interface and a radio unit without interference from dielectric materials, which typically requires a significant distance between these components, leading to bulky designs that are not practical for wearable or compact applications.

Innovation Solution

The solution involves spatially separating user input operations from detection means, allowing them to be positioned close to the antenna while maintaining a shielding distance, thereby optimizing the use of three-dimensional space and reducing the overall device size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If dielectric materials are placed close to the antenna for compact design, then device size is reduced, but antenna operation is disturbed

Engineering Contradiction:
Improvedevice sizeVSAvoidantenna operation
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The user interface is divided into two separate components: interface means (display and input elements) and detection means (sensors). This segmentation allows the interface means to be positioned close to the antenna while keeping dielectric detection means at an appropriate distance, resolving the contradiction between compact size and reliable antenna operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A non-conductive rod or similar intermediary structure is used to connect the interface means with the detection means. This intermediary allows the interface elements to be positioned independently from the dielectric detection components, enabling close proximity to the antenna without disturbing its operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If interface means and detection means are integrated in the same location, then device complexity is reduced, but shielding distance requirements cannot be met

Engineering Contradiction:
Improveinterface structureVSAvoidshielding distance
Core Design Contradiction:
Device complexityVSLength of stationary object

Solution Approach 1:

The system transitions from a two-dimensional planar arrangement to a three-dimensional configuration. The non-conductive rod extends in the vertical dimension, allowing the interface means to be positioned above or near the antenna while the detection means remains at the required shielding distance, effectively utilizing spatial dimensions to resolve the contradiction.

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