Solution Overview

Problem

E-reader devices lack an efficient and ergonomic method for user input, particularly for page turns, as they typically require manual buttons or screens, which can be cumbersome and disrupt reading experiences.

Innovation Solution

A computing device with a touch-sensitive housing that detects contact-separation inputs, allowing users to initiate operations like page turns by lifting fingers off the device, utilizing multiple touch sensors integrated into the housing to interpret user interactions and execute corresponding instructions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual buttons or screens are used for input, then device functionality is provided, but user interaction becomes cumbersome and reading experience is disrupted

Engineering Contradiction:
Improveuser interactionVSAvoidinput mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the input function from traditional buttons and screens and integrates it into the housing surface itself. The housing includes a touch-sensitive surface that can detect contact-separation gestures, allowing users to interact with the device by lifting their fingers off the housing surface while reading on the display screen without obstruction.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The housing serves multiple functions: it provides structural support, includes touch-sensitive input surfaces for user interaction, and maintains display functionality. The touch-sensitive housing surface can detect various gestures (single tap, double tap, hold, swipe) that translate into different commands, making the housing a multi-functional input device.

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

2Adaptability or versatility

If additional buttons are added for input, then input functionality is improved, but device design becomes more complex and screen visibility is obstructed

Engineering Contradiction:
Improveinput functionalityVSAvoiddevice design
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The patent merges the input functionality with the housing structure itself. Instead of adding separate buttons, the housing surface is made touch-sensitive, combining the structural and input functions into a single integrated component. This eliminates the need for additional buttons while maintaining full input capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The input interface is moved to a different spatial dimension - the housing surface surrounding the display rather than being part of the display itself. This allows input functionality to be added without obstructing the screen, as users interact with the housing surface while the display remains fully visible.

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

3Ease of operation

If touch-sensitive housing is used, then ergonomic input is enabled, but manufacturing complexity increases

Engineering Contradiction:
Improveergonomic inputVSAvoidhousing manufacturing
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The housing surface is modified by applying a touch-sensitive coating or layer that changes the electrical properties of the housing surface. This allows the housing to detect touch gestures without requiring complex mechanical button structures, simplifying the overall manufacturing process while enabling ergonomic input.

Inventive Principle:
Principle #35Parameter changes

AI summary

A computing device includes a housing and a display assembly having a screen. The housing at least partially circumvents the screen so that the screen is viewable. A first touch sensor is provided with a first portion of the housing. For example, the first touch sensor may be provided on a sidewall, a front surface, or a back surface of the housing. A processor is provided within the housing to detect a first user interaction and a second user interaction with the first touch sensor. The first user interaction corresponds with a user making contact with the first touch sensor, and the second user interaction corresponds with the user releasing contact with the first touch sensor. The processor further executes a first set of instructions in response to detecting the second user interaction.
