Solution Overview

Problem

Existing car footboards are cumbersome, fail to adapt to various car door frames, and can damage the door frame or provide an unstable standing surface due to their inflexible design.

Innovation Solution

An adjustable car latch footboard that hinges on a pivot, with a hook attached to the car latch and a bracket component that can be pressed against the door frame, allowing for horizontal adjustment and secure positioning, featuring a scissor-like structure with interlocking mechanisms and non-slip surfaces for stability and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a common footboard is used, then it can provide a standing surface, but it is huge and inconvenient to carry

Engineering Contradiction:

Improveconvenience to carryVSAvoidsize of footboard

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The footboard is divided into multiple segments that can fold relative to each other, allowing the structure to collapse into a compact form for easy storage and transport, while still providing adequate standing surface area when deployed

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The footboard segments are designed to nest within each other when folded, creating a compact package that minimizes storage volume while maintaining full functionality when in use

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a simple structure footboard is used, then it is easy to manufacture, but it can't adapt to various car door frames

Engineering Contradiction:

Improveadaptability to car door framesVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The footboard incorporates adjustable mechanisms that allow it to dynamically adapt to different door frame configurations, with movable components that can be positioned to match various geometries while maintaining structural integrity

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The footboard structure includes adjustable parameters such as angle, length, and position that can be modified to accommodate different car door frames, transforming a fixed-geometry structure into a variable-geometry adaptation system

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If a rigid footboard is used, then it provides stable support, but it may damage the car door frame

Engineering Contradiction:

Improvestability of footboardVSAvoiddamage to car door frame

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The footboard incorporates flexible or compliant elements at contact points with the door frame, allowing the structure to yield slightly under load and distribute forces evenly, preventing concentrated stresses that could damage the door frame while maintaining overall stability

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The design includes cushioning or protective elements at the interfaces between the footboard and door frame that preemptively absorb or distribute impact forces, preventing damage before it occurs during use

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Stability of the object's composition

If an inflexible footboard is used, then it is simple in structure, but it may not be level and doesn't allow stable standing

Engineering Contradiction:

Improvestability for standingVSAvoidadjustment mechanism complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The footboard includes adjustable components that allow the structure to be configured at different angles and positions, enabling it to achieve a level orientation on various door frames while providing stable support for standing

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The adjustment mechanisms incorporate feedback features such as locking positions or visual indicators that help the user achieve proper leveling and stable configuration without requiring complex measurement or adjustment procedures

Inventive Principle:

Principle #23Feedback

AI summary

This invention relates to an auxiliary tool for automobiles, specifically an adjustable car latch footboard that includes a footboard, a hook, a bracket component, and a pivot. The footboard hinges on the bracket component through the pivot, and the hook is mounted at one end of the bracket component opposite to the other end of the footboard. The hook is attached to the car latch, and the other end of the bracket component is pressed against the car door frame. One end of the footboard is pressed against the hook or the car latch. When the footboard is pressed against the hook, the car latch is positioned between the footboard and the hook. When the footboard is pressed against the car latch, the footboard and the hook grip onto the car latch.
