Solution Overview

Problem

Wireless hand-held remote control devices for powered chairs are prone to misplacement and require frequent recharging, as they lack a dedicated docking solution that integrates seamlessly with the chair's structure, leading to inconvenience and inefficiency in operation.

Innovation Solution

A wireless hand-held remote control device with a dock that is fixedly secured within the chair's arm section, featuring a magnetic interface for secure storage and automatic charging, ensuring proper alignment and accessibility of control buttons, and a charging interface for maintaining battery power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wireless hand-held remote-control device is used to control powered chairs, then the device can be located anywhere and is not restricted by wire length, but the device may become misplaced or lost due to lack of a designated storage location

Engineering Contradiction:
Improvewireless freedom of movementVSAvoiddevice location tracking
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The remote control device is nested within a receptacle that is integrated into the chair structure. The receptacle provides a designated storage location within the chair armrest, ensuring the remote is always returned to a known position after use, thus preventing misplacement while maintaining wireless operation freedom.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If a wireless hand-held remote-control device operates on battery power, then the device is portable and independent of wall sockets, but the battery needs periodic recharging which requires external recharging devices

Engineering Contradiction:
Improveportability and independence from wall socketsVSAvoidtime for battery recharging
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The receptacle integrated into the chair includes a battery charging circuit that automatically charges the remote control device when it is placed in the receptacle. This self-service charging mechanism eliminates the need for external recharging devices and reduces the time and effort required for battery maintenance, as the remote is recharged passively during storage.

Inventive Principle:
Principle #25Self-service

3Use of energy by moving object

If external recharging devices are used for wireless remote control devices, then the remote can be recharged, but the recharging devices must be placed on external surfaces of the chair or on tables adjacent to the chair

Engineering Contradiction:
Improvebattery recharging capabilityVSAvoidexternal recharging device placement
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The battery charging circuit is merged with the chair structure itself, specifically integrated into the receptacle within the armrest. This consolidation eliminates the need for separate external recharging devices and their associated placement requirements, simplifying the overall system while maintaining full recharging functionality.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case
