Sliding-Arm Security Mount for Reliable Handheld Device Alarms
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, hindering customer inspection and increasing retailer vulnerability.
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 maintaining customer access for inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alarm sensors are attached using adhesive tape to handheld electronic devices, then security monitoring is enabled, but the adhesive often fails during use causing false alarms and disrupting customer shopping experience
Solution Approach 1:
The patent introduces a mechanical mounting structure (clamping mechanism with sliding arms and retention members) as an intermediary between the alarm sensor and the handheld device. This mediator provides reliable sensor attachment through mechanical pressure rather than adhesive, ensuring consistent contact without the reliability issues of adhesive failure that cause false alarms.
2Reliability
If multiple alarm sensors are installed in multiple locations on handheld electronic devices, then theft prevention coverage is improved, but customer inspection of the device is hindered
Solution Approach 1:
The patent segments the security function into two independent components: (1) a mechanical mounting structure that provides secure attachment and consistent sensor contact, and (2) the alarm sensor itself. This segmentation allows the sensor to be positioned optimally for theft detection while the mounting structure ensures reliable operation, resolving the conflict between comprehensive security coverage and customer inspection accessibility.
3Reliability
If alarm sensors are attached firmly to handheld electronic devices, then security monitoring reliability is improved, but the sensors can ignite when subjected to excessive heat within the devices
Solution Approach 1:
The mechanical clamping structure serves as a heat-isolating intermediary between the alarm sensor and the handheld device. By using a mounting structure with sliding arms and retention members rather than direct adhesive attachment, the patent creates thermal separation that reduces heat transfer to the sensor, eliminating the ignition risk while maintaining reliable sensor contact through mechanical pressure.
