Solution Overview

Problem

Existing solutions fail to effectively limit user access and control of mobile electronic devices in specific geographic locations or during certain times, leading to distractions and potential infringement of intellectual property rights at communal events.

Innovation Solution

A locking case with a locking mechanism that uses RFID, Bluetooth, or other wireless signals to restrict access to mobile devices within defined areas or during specified periods, ensuring the device remains inaccessible until the user leaves the venue or a predetermined condition is met.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a locking case with RFID/Bluetooth signals is used to restrict device access in defined areas, then distractions and unauthorized recordings are prevented, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvedistractions and unauthorized recordingsVSAvoidlocking case system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent introduces a locking case as an intermediary device between the user and their electronic device. The locking case contains RFID or Bluetooth signal generators that create a restricted zone, automatically preventing device access when detected within the zone. This intermediary system resolves the contradiction by providing automated harm prevention without requiring complex user decisions or manual intervention.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The locking case system operates autonomously using RFID or Bluetooth signal detection to automatically lock or unlock device access. The system self-regulates based on proximity detection, eliminating the need for manual locking/unlocking by the user. This self-service mechanism reduces the perceived complexity for users while maintaining effective control.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If manual locking mechanisms are used to prevent device access, then control over device usage is achieved, but ease of operation deteriorates due to required user intervention

Engineering Contradiction:
Improvedevice usage controlVSAvoiduser intervention requirement
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The locking case automatically detects when a user approaches via RFID or Bluetooth signals and autonomously locks the device compartment. When the user leaves the restricted zone, the system automatically unlocks. This eliminates the need for manual locking/unlocking operations, significantly improving ease of operation while maintaining effective device usage control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors RFID/Bluetooth signal presence and provides real-time feedback by automatically adjusting the lock state. This feedback mechanism ensures the device is locked when needed and unlocked when appropriate, achieving effective control without requiring user intervention or decision-making.

Inventive Principle:
Principle #23Feedback

3Object-affected harmful factors

If devices are completely blocked in restricted areas, then unauthorized recordings are prevented, but loss of information occurs as users cannot access important notifications

Engineering Contradiction:
Improveunauthorized recordingsVSAvoidmissed notifications
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The locking case implements partial blocking by allowing the device to remain physically accessible in the case while electronically preventing specific functions (recording, photography) through signal restriction. The device can still receive and display notifications, providing selective control that prevents harmful actions while maintaining access to important information.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system applies different control qualities to different device functions within the restricted zone. Recording and photography functions are completely blocked, while notification reception and display remain accessible. This localized quality control prevents unauthorized recordings while avoiding complete information isolation.

Inventive Principle:
Principle #3Local quality

4Object-affected harmful factors

If users are required to leave devices at home or turn them off, then distractions are eliminated, but ease of operation worsens due to inconvenience and security concerns

Engineering Contradiction:
Improvedistractions at eventsVSAvoiduser convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The locking case serves as a portable intermediary that users can bring to events, eliminating the need to leave devices at home. The automated RFID/Bluetooth-based locking system provides distraction-free zones while keeping devices physically accessible and secure, resolving the contradiction between eliminating distractions and maintaining user convenience.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system automatically manages device locking and unlocking based on user proximity, eliminating the need for manual intervention. Users simply approach or leave the restricted zone, and the system handles all locking operations autonomously, providing convenience comparable to having no restrictions while effectively eliminating distractions.

Inventive Principle:
Principle #25Self-service

AI summary

A system and apparatus for selectively limiting user control of a mobile electronic device are provided. In an embodiment, the apparatus may be a case sized to receive a mobile electronic device, the case having a locking means to at least partially secure an opening thereof. When engaged, the locking means may be physically impenetrable by the user of the mobile electronic device and may further be configured to engage and disengage in the presence of one or more pre-determined conditions. For example, the lock may engage when the case is detected within a certain geographical region or even during a specified time. It is contemplated that providing disclosed systems and apparatuses may reduce undesirable behavior at communal events by eliminating distractions posed by mobile electronic devices and preventing unauthorized recordings, which together may enhance overall engagement at and enjoyment of such events.
