Armrest production process and armrest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing armrest production methods face challenges such as variations in surface texture, density, and color between different wood materials, leading to inconsistent appearance quality, and result in significant wood waste during shaping.
Innovation Solution
The proposed armrest production process involves cutting high-grade wood materials into identical upper covers and lateral boards, which are then spliced onto a core made from lower-grade or recycled wood materials, ensuring uniformity and reducing material waste by optimizing cutting patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If different wood materials are used for core sections and surface boards, then material cost is reduced, but appearance quality deteriorates due to variations in surface texture, density, and color
Solution Approach 1:
The patent applies local quality by using different material grades for different parts of the armrest. The core sections use lower-grade wood materials for structural support, while the surface layer uses higher-grade wood materials with consistent texture and color for aesthetic appearance. This localized differentiation of material quality resolves the contradiction between cost reduction and appearance quality maintenance.
Solution Approach 2:
The patent employs composite material construction by bonding surface boards to core sections made from different wood materials. This composite structure allows the armrest to combine the structural efficiency of lower-grade materials with the aesthetic qualities of higher-grade materials, simultaneously achieving cost reduction and appearance quality.
2Ease of manufacture
If traditional splicing method is used to form armrest, then production process is simplified, but wood waste increases due to significant material removal during shaping
Solution Approach 1:
The patent applies preliminary action by pre-cutting the surface boards and core sections with optimized dimensions and shapes before assembly. The surface boards are cut to match the desired final outline of the armrest, and the core sections are pre-shaped to reduce material removal requirements. This preliminary preparation reduces wood waste during the final shaping process while maintaining production simplicity.
