Solution Overview

Problem

Existing electronic books require embedding switches or sensors into pages to provide interactive features, which complicates their design and functionality.

Innovation Solution

The integration of capacitive touch elements on the inside of book covers and a controller connected to an output device, allowing users to interact with the book by touching or tracing over text or images, without the need for embedded switches or sensors, using capacitive touch technology to detect user input and trigger corresponding audio or visual responses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If switches or sensors are embedded into pages to provide interactive features, then interactivity is improved, but device complexity increases

Engineering Contradiction:
ImproveinteractivityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the sensing elements from the pages and relocates them to the covers. The capacitive touch elements are disposed on the inside of the covers rather than embedded in the pages, simplifying page construction while maintaining interactive functionality through the cover structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The covers serve multiple functions: they provide structural protection for the book and simultaneously house the capacitive touch elements for user interaction. This multi-functionality eliminates the need for separate sensing components in the pages, reducing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If capacitive touch elements are placed on covers instead of embedding sensors in pages, then device complexity is reduced, but measurement precision may be affected

Engineering Contradiction:
Improvedevice complexityVSAvoidtouch detection precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The capacitive touch elements on the covers act as intermediaries that detect user touch through the pages. The controller receives signals from these cover-mounted elements and determines the corresponding position on the overlaid page, maintaining measurement precision without requiring direct page embedding.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces mechanical embedding of sensors into pages with an electrical field-based capacitive detection system on the covers. This substitution allows touch detection through the page structure without physical modification of the pages, maintaining precision while simplifying the system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A book (1) is described. The book has front and back covers (2, 3) and a plurality of pages (5) bound between the covers. The book includes capacitive touch elements (9) disposed on the inside (10, 14) of the back cover and/or the front cover. The book also includes at least one output device (7), such as a speaker, and a controller. The controller is configured to cause the or at least one of the output devices to output a signal in dependence upon position of a user's digit on a page overlying the cover.
