Battery Pack Security Device with Cuttable Strap and Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security devices for battery packs are difficult to remove in stores but hard to detach outside, and they lack ease of attachment and effective deterrence against theft.
Innovation Solution
A security device comprising a cap and strap configuration that covers the slide mechanism of a battery pack, with projections and collars that secure the cap to the strap, and an optional sensor for theft detection, allowing easy removal with a cutting tool after purchase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security device is designed to be hard to remove in stores, then theft deterrence is improved, but ease of removal after purchase deteriorates
Solution Approach 1:
The security device employs different structural characteristics at different locations: the cap features collars and projections that create friction and mechanical interference for difficult removal in stores, while the same cap can be easily cut with scissors at the projection location after purchase. This local differentiation of structural properties resolves the contradiction between secure attachment and easy removal.
2Reliability
If a security device is designed to be conspicuous when removal is attempted, then theft deterrence is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated cap structure: the cap simultaneously provides mechanical attachment via projections, friction-based retention via collars, and potential sensor housing. This merging of functions achieves effective theft deterrence without proportionally increasing device complexity, as one component serves multiple security-related purposes.

AI summary
A security device for a battery pack includes a cap, which covers at least a portion of a slide mechanism of a slide battery pack, and a strap. The cap includes a first collar disposed around a first opening and a second collar disposed around a second opening, with the first collar and the second collar aligned along a longitudinal axis of the slide battery pack. The strap matches a contour of the slide battery pack and includes a first projection and a second projection. The strap is positioned along the longitudinal axis of the slide battery pack and the cap is positioned over the strap with the first projection inserted through the first opening and the first collar and the second projection inserted through the second opening and the second collar to secure the cap to the strap and to the slide battery pack.
