Solution Overview

Problem

Existing security apparatuses for portable electronic devices often struggle to accommodate different slot widths on various devices, limiting their versatility and effectiveness.

Innovation Solution

A security apparatus with a modular design, featuring interchangeable plungers of different widths that can be easily swapped to accommodate slots of varying widths, allowing the apparatus to securely engage a wide range of portable electronic devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-width engagement member is used in the security apparatus, then the structure is simple and reliable, but the apparatus can only accommodate slots of a specific width, reducing versatility

Engineering Contradiction:
Improvecompatibility with different slot widthsVSAvoidstructure of security apparatus
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The engagement member is divided into modular components: a body portion and an interchangeable plunger portion. The plunger can be removed and replaced with different width plungers to accommodate various slot widths, enabling the security apparatus to adapt to different device configurations without redesigning the entire engagement member.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The engagement member body is designed as a universal component that can work with multiple types of plungers having different widths. This allows a single engagement member body to serve multiple functions by simply changing the plunger attachment, making the security apparatus compatible with various slot widths across different portable electronic devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If interchangeable plungers are added to accommodate different slot widths, then versatility is improved, but the device complexity and number of components increases

Engineering Contradiction:
Improverange of slot widths accommodatedVSAvoidnumber of plunger components
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The plunger components are designed to be easily removable and replaceable. When a plunger wears out or needs to be changed for a different slot width, it can be quickly discarded and replaced with a new or different plunger without requiring specialized tools or complex disassembly procedures.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The plunger fits within the engagement member body in a nested configuration, where the plunger is received by and integrated with the engagement member. This nested design allows the plunger to be stored within the engagement member when not in use and enables quick interchange without requiring separate storage compartments for each plunger type.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A security apparatus for a portable electronic device includes a lock body, an engagement member supported by the lock body, and a lock tip configured to selectively engage the portable electronic device. The lock tip is movable by the engagement member between an engaged position, in which the lock tip is secured to the portable electronic device, and an disengaged position, in which the lock tip is unsecured from the portable electronic device. The lock tip includes a first finger and a second finger that engage the portable electronic device in the engaged position, and a plunger that extends between the first and second fingers and is movable by the engagement member. The plunger includes an engagement feature configured to removably engage the engagement member such that the plunger is selectively removable by a user.
