Security device for functional display and security of handheld electronic devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security measures for handheld electronic devices, such as alarm sensors attached with adhesive, often fail to prevent theft due to false alarms and limited coverage, leading to retailers ignoring alarms and increased vulnerability to theft.
Innovation Solution
A security device with sliding arms and a leveling plate that securely holds the device, allowing for adjustable retention and integration of an alarm sensor to prevent tampering, while enabling functional display and inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alarm sensors are attached to handheld electronic devices using adhesive, then security monitoring is enabled, but the adhesive often fails causing false alarms and loss of contact
Solution Approach 1:
The security device is divided into separate components: a base unit and multiple detachable alarm sensors. Each sensor can be independently attached to different locations on the device, allowing reliable security monitoring while enabling easy removal and repositioning for customer inspection without adhesive failure issues.
Solution Approach 2:
The alarm sensors are designed to be dynamically repositionable rather than fixed. The sensors can be moved between different locations on the handheld device and easily attached/detached as needed, providing both reliable security coverage and flexibility for customer access during inspection.
2Reliability
If multiple alarm sensors are installed in multiple locations on the device, then theft prevention coverage is improved, but customer inspection is hindered
Solution Approach 1:
Multiple alarm sensors are segmented into separate, independently positionable units rather than being permanently fixed. This allows the sensors to be strategically placed in multiple locations for comprehensive theft prevention while enabling customers to easily move them aside or remove them for full inspection access.
Solution Approach 2:
The alarm sensors act as temporary intermediaries during display rather than permanent obstacles. They can be easily removed or repositioned to allow customer inspection, then reinstated for security, serving as a flexible mediator between security requirements and customer access needs.
3Reliability
If alarm sensors are attached firmly to the device, then security monitoring reliability is improved, but false alarms increase due to adhesive failure
Solution Approach 1:
The attachment mechanism is made dynamic rather than static. The alarm sensors can be firmly attached when needed for reliable security monitoring and easily removed or repositioned to prevent adhesive failure and false alarms. This dynamic attachment eliminates the harmful effect of adhesive degradation over time.
Solution Approach 2:
The security device performs self-adjustment through easy repositioning of the alarm sensors. When adhesive shows signs of failure or false alarms occur, the sensors can be quickly removed and reattached to fresh surfaces, allowing the system to self-correct without professional intervention and maintain reliable operation.
4Ease of manufacture
If adhesive is used to attach alarm sensors, then installation simplicity is improved, but contact stability deteriorates over time
Solution Approach 1:
The attachment system is segmented into reusable components rather than relying on permanent adhesive bonding. Each alarm sensor can be independently attached and detached, maintaining installation simplicity while eliminating the stability deterioration problem caused by adhesive aging and failure.
Solution Approach 2:
The alarm sensors are designed as disposable or easily replaceable components rather than permanent installations. When attachment stability deteriorates, the sensors can be quickly replaced without complex tools or procedures, maintaining both installation simplicity and contact stability over time.
