Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional mobile electronic device protecting covers do not provide a convenient method for storing a touch pen, as they require manual switching to turn the pen's power on and off and lack assurance that the power is correctly toggled when inserting or removing the pen.

Innovation Solution

A mobile device protecting cover with a touch pen slot that automatically turns off the pen's power when inserted and turns it on when removed, featuring a press switch button and a guide slope for smooth insertion and removal, along with a power light for verification and heat dissipation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional protecting cover is used to store a touch pen, then the pen can be stored in the cover, but the user must manually press the switch to turn the power off before insertion and turn it on after removal, which is inconvenient and time-consuming

Engineering Contradiction:

Improveconvenience of storing and removing touch penVSAvoidtime required for manual switching operations

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The protecting cover is designed with a press switch button that automatically presses the touch pen's power switch during insertion, turning it off before the pen is stored. During removal, the button automatically presses the switch to turn the power on, eliminating the need for manual pre-action by the user

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The protecting cover structure itself performs the power switching function through its design features (press switch button positioned to contact the pen's switch during insertion/removal), making the cover self-serving rather than requiring separate manual user actions for power control

Inventive Principle:

Principle #25Self-service

2Loss of information

If a conventional protecting cover stores a touch pen, then the pen is stored, but there is no way for users to know whether the switch has been triggered to turn on the power

Engineering Contradiction:

Improvefeedback information about power statusVSAvoiddifficulty of detecting power switch status

Core Design Contradiction:

Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The protecting cover includes a power light that provides visual feedback to the user about the power status of the touch pen. The power light illuminates to indicate when the power is on or off, allowing users to immediately know whether the switch has been triggered without needing to separately check the pen's status

Inventive Principle:

Principle #23Feedback

3Temperature

If the touch pen is stored in a conventional protecting cover, then the pen is stored, but the pen generates heat that cannot be effectively dissipated

Engineering Contradiction:

Improveheat dissipation of touch penVSAvoidheat accumulation in stored pen

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The protecting cover utilizes its shell structure with strategically designed openings and ventilation channels that allow heat to escape from the stored touch pen. The thin film or shell material permits thermal exchange with the external environment, preventing heat accumulation inside the cover

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A mobile device protecting cover capable of storing a touch pen includes a touch pen slot and an insertion port disposed on the back side of the protecting cover. The touch pen slot has a press switch button disposed on an inner side wall for pressing the touch pen, and the inner side wall has a groove configured to be corresponsive to the press switch button, and extended from the insertion port as a starting end towards the other end of the touch pen slot. The protecting cover is used to cover a mobile phone or a tablet PC and insert the touch pen into the touch pen slot. When the touch pen is inserted or removed, the structure of the groove and the inner side wall achieves main effect of turning on or off the power by the touch pen.
