Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tailgate structures fail to securely attach heavy functional components like wipers to the vehicle body, leading to potential separation and scattering during load input, which can endanger passengers.
Innovation Solution
A tailgate structure featuring a resin tailgate with a metal wire reinforcing member connecting the wiper to a lock device, ensuring the wiper remains attached even if the tailgate is subjected to load input, using metal wire members that can deform to accommodate temperature changes and provide additional rigidity through multiple connection points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a resin tailgate is used with standard mounting, then manufacturing cost and ease of manufacture are improved, but the wiper may separate from the tailgate under load input, compromising safety and reliability
Solution Approach 1:
The patent employs a composite construction combining resin tailgate panels with metal reinforcing members (wires or plates) and metal lock devices. The metal components provide the necessary strength and rigidity to prevent wiper separation under load, while the resin panels maintain ease of manufacture and aesthetic properties. This composite approach resolves the contradiction by integrating materials with complementary properties.
Solution Approach 2:
The patent utilizes curved or bent metal wire reinforcing members that are deformed to fit specific mounting configurations. The wire members are bent into curved shapes that accommodate the tailgate geometry and provide optimized load distribution. This curvature allows the reinforcing members to effectively resist separation forces while maintaining ease of installation.
2Weight of moving object
If the tailgate is made of resin material, then weight is reduced and ease of manufacture is improved, but rigidity and collision resistance are insufficient, causing cracking and component scattering
Solution Approach 1:
The patent creates a composite structure where lightweight resin panels are reinforced with high-strength metal components. The metal reinforcing members and lock devices provide the necessary strength and collision resistance, while the resin panels maintain low weight. This composite material approach allows the tailgate to achieve both lightweight properties and high strength simultaneously.
Solution Approach 2:
The tailgate structure is divided into separate functional components: resin panels for weight reduction and aesthetics, metal reinforcing members for strength, and metal lock devices for secure mounting. This segmentation allows each component to be optimized for its specific function while working together as an integrated system that achieves both low weight and high strength.
3Device complexity
If heavy functional components like wipers are mounted only on the tailgate, then device complexity is reduced, but the components may separate and fall inside or outside the vehicle under load, compromising safety
Solution Approach 1:
The patent introduces metal lock devices and metal wire reinforcing members as intermediary components between the wiper assembly and the tailgate. These intermediary elements provide a secure mechanical connection that prevents direct separation of the wiper from the vehicle body, even when the tailgate itself is subjected to load. This intermediary connection resolves the safety issue while maintaining relatively simple device architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents the wiper from falling off or scattering, maintaining passenger safety by ensuring the wiper remains connected to the tailgate even under load input, with the metal wire members providing strong resistance and stability across various temperature conditions.
Implementation Method 1
the wiper is connected with the lock device by a reinforcing member... both ends of the reinforcing member can strongly resist the force which woks to disconnect the wiper from the lock device
Implementation Method 2
the wire member is easily deformable and even if it is mounted by bending in consideration of expansion and contraction due to temperature change
