Tailgate Handle Base Reinforcement via Flexible Tab Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Old generation car tailgate handle bases, particularly in older pickup trucks, are prone to breaking due to inadequate durability and strength, leading to functional failures and difficulties in obtaining replacement parts.
Innovation Solution
A reinforcement and repair structure for the car tailgate handle base is introduced, featuring a handle base with a pivot pin, reinforcing pins with tab slots, and a flexible tab that forms a flat spring portion, which is inserted into the tab slot to engage with the reinforcing pin, enhancing durability and resistance to wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If old generation plastic materials are used for car tailgate handle bases, then manufacturing cost is reduced and ease of manufacture is improved, but durability and strength deteriorate, leading to easy breakage under stress and vibration
Solution Approach 1:
The patent applies composite materials by combining metal reinforcing pins with the plastic handle base structure. The reinforcing pins are embedded within the plastic base to create a composite structure that leverages the strength of metal and the ease of manufacturing of plastic, thereby improving durability while maintaining manufacturing simplicity
Solution Approach 2:
The patent applies local quality by adding reinforcing pins specifically at critical stress points within the handle base structure. Instead of making the entire base from stronger material, reinforcement is localized to areas most prone to breakage under vibration and stress, improving durability where needed while keeping overall manufacturing simple
2Reliability
If the car tailgate handle base is reinforced with additional pins and structures, then durability and strength are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the reinforcement function into separate, modular reinforcing pins that are independently embedded in the plastic base. Each pin serves as an independent reinforcement element, allowing the complex strengthening function to be achieved through simple, discrete components rather than a complex integrated structure
Solution Approach 2:
The patent applies nesting by embedding the metal reinforcing pins within the plastic handle base structure. The pins are nested inside the plastic material, creating a layered composite structure where the reinforcement elements are contained within the main body, adding strength without increasing external complexity
3Ease of repair
If replacement parts are obtained for old pickup trucks, then repair capability is improved, but availability is poor and cost is high, making frequent replacement necessary
Solution Approach 1:
The patent applies this principle by designing a reinforcement structure that uses inexpensive metal pins and plastic components that can be easily replaced. Rather than requiring expensive, hard-to-find original replacement parts, the system uses simple, affordable reinforcement elements that can be readily obtained and installed, making repair economical and accessible

Function Achieved in This Case
The solution significantly increases the durability of the car tailgate handle base, reducing the likelihood of breakage under stress and vibration, and allows for easy repair without the need for frequent replacement with new parts.
Implementation Method 1
the other part is raised to form a flat spring portion; wherein, the flexible tab is inserted into the tab slot through the joint to be combined with the reinforcing pin

AI summary
A car tailgate handle base reinforcement and repair structure is designed to be integrated with a car tailgate handle joint. It comprises the following features: a handle base with one side being a connecting surface and the other side being an exposed surface. The connecting surface has a pivot pin on one side and an elastic pin on the opposite side. At least one reinforcement pin, placed at an appropriate location on the connecting surface, and equipped with a tab slot. A flexible tab, with one part of the tab being shaped to correspond with the tab slot's interior and the other part forming a flat spring portion. In this structure, the flexible tab is inserted into the tab slot through the connecting part, forming a connection with the reinforcement pin.
