Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing seatback pocket assembly has a high number of parts, leading to increased cost and weight, as well as complex workmanship, which affects the product's quality and price competitiveness.
Innovation Solution
A compact assembly structure for the seatback pocket using a backboard, a pocket member with a hinge part, and an elastic member, reducing the number of parts to three, with the backboard and pocket member being injection molded for improved quality and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional seatback pocket assembly with multiple parts (backboard, backboard covering, pocket covering, sub-pocket panel, main pocket panel, fixing stick, return spring) is used, then the quality, strength, and durability are improved, but the cost, weight, and manufacturing complexity increase
Solution Approach 1:
The patent combines multiple separate components into an integrated injection-molded single piece. The backboard, backboard covering, pocket covering, sub-pocket panel, and main pocket panel are merged into one monolithic structure, eliminating the need for fixing sticks and reducing the number of parts while maintaining structural integrity and quality
Solution Approach 2:
The single integrated component performs multiple functions that were previously distributed across separate parts: structural support, covering, pocket formation, and attachment mechanisms are all incorporated into one universal part, reducing complexity while maintaining reliability
2Strength
If multiple separate components are used to assemble the seatback pocket, then the structural strength and durability are improved, but the weight and manufacturing cost increase
Solution Approach 1:
Multiple components are merged into a single injection-molded part, eliminating the weight of fasteners, joints, and overlapping materials while maintaining structural strength through integrated design and continuous material structure
Solution Approach 2:
The injection molding process uses composite material formulations that provide both strength and weight efficiency, creating a single-piece structure that achieves the required structural integrity without the additional weight of multiple assembled components
3Duration of action of stationary object
If multiple separate components are used for the seatback pocket assembly, then the durability is improved, but the manufacturing cost and workmanship complexity increase
Solution Approach 1:
The patent merges multiple manufacturing steps and assembly operations into a single injection molding process, eliminating the need for separate production of individual components and their subsequent assembly, thereby reducing manufacturing cost and complexity while maintaining durability
Solution Approach 2:
The injection molding process performs preliminary actions by forming the complete multi-functional structure in one step, including integrated attachment features and pocket formations, eliminating the need for subsequent assembly operations and reducing manufacturing complexity
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 reduced number of parts significantly decreases the cost and weight of the seatback pocket while maintaining quality and improving productivity through simplified manufacturing and injection molding.
Implementation Method 1
an elastic member connected between both ends of the pocket member and the backboard in a shape blocking sides of the pocket space, and being configured to provide an elastic restoring force with respect to a rotation direction of the pocket member of which the pocket space is expanded
