Solution Overview

Problem

Current mounting platforms for vehicle-mounted accessories are prone to theft and do not securely hold devices during vibrations or shocks, leading to potential damage.

Innovation Solution

A mounting platform with a rigid frame and tray interconnected via a tongue-and-groove slide mechanism, featuring a resilient biasing mechanism for secure attachment and a keyed lock mechanism for tamper-proof security, ensuring the tray is securely locked to the frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a simple mounting platform is used, then ease of manufacture is improved, but security against theft and device stability during vibration is worsened

Engineering Contradiction:
Improveease of manufactureVSAvoidsecurity against theft and device stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The mounting platform is divided into separate components: a base, a tray, a latch mechanism with bolt and strike plate, and a keyed lock mechanism. This segmentation allows each component to be manufactured independently using standard processes while providing complex security and stability functions when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The latch mechanism with bolt and strike plate serves as an intermediary between the simple structural components and the security requirement. The keyed lock mechanism acts as a second intermediary providing tamper-proof security. These intermediary elements transform a simple mounting structure into a secure system without requiring complex integration.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a secure locking mechanism is added, then security against theft is improved, but device complexity is worsened

Engineering Contradiction:
Improvesecurity against theftVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The latch mechanism is designed to be self-actuating through the resilient biasing mechanism that automatically engages the bolt with the strike plate when the tray is inserted. The keyed lock mechanism provides automatic engagement of the lock bolt with the lock mortise, eliminating the need for complex control systems or multiple operating steps.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces electronic locking systems or complex multi-component security mechanisms with straightforward mechanical elements: a latch bolt with resilient biasing, a strike plate with inclined surface, and a keyed lock with bolt and mortise. These mechanical substitutions provide robust security while maintaining simplicity in design and operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If a resilient biasing mechanism is used, then device stability during vibration is improved, but ease of operation is worsened

Engineering Contradiction:
Improvedevice stability during vibrationVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The resilient biasing mechanism converts the harmful vibrational forces and shocks into beneficial engagement pressure. During vehicle motion, vibrations that would normally loosen connections are converted by the resilient element into continued engagement force between the latch bolt and strike plate, actually strengthening the connection under dynamic conditions.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The latch mechanism requires no manual adjustment or operation during normal use. The resilient biasing mechanism continuously maintains engagement pressure automatically, and the keyed lock remains engaged without intervention. Users simply insert and remove the tray as needed, with the mechanism self-regulating during vehicle motion.

Inventive Principle:
Principle #25Self-service

4Reliability

If a keyed lock mechanism is provided, then tamper-proof security is improved, but manufacturing cost is worsened

Engineering Contradiction:
Improvetamper-proof securityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The keyed lock mechanism is provided as a separate, modular component that can be manufactured and installed independently. This segmentation allows the use of standard, off-the-shelf lock cylinders and bolts rather than custom-machined integrated locking systems, significantly reducing manufacturing cost while maintaining tamper-proof security.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The keyed lock mechanism serves as an intermediary security layer that works independently of the main latch mechanism. The lock bolt engages with the lock mortise to provide tamper-proof security, while the main latch handles routine tray retention. This intermediary approach allows each mechanism to be optimized for its specific function using cost-effective manufacturing methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An accessory device mounting platform includes a substantially rigid frame and a substantially rigid mating tray that are slidably interconnected along a first direction, the frame and tray include a tongue-and-groove slide mechanism arranged therebetween for sliding the tray relative to the frame relative to a first direction. A resilient biasing mechanism, such as a cantilevered flexure or tension spring, is coupled between the frame and a latch bolt portion of a clasp mechanism for biasing the latch bolt portion toward a latch strike plate mechanism formed in the tray. The latch strike plate mechanism is formed with an inclined surface that is positioned to engage a latch bolt portion of the clasp mechanism and is structured for deflecting the latch bolt away from the frame, while the resilient biasing mechanism of the clasp mechanism is structured for biasing the latch bolt back toward the frame.
