Laser-Processed Wooden Patch with Adhesive Resin Backing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing accessories using rubber, resin, and metal materials result in environmentally unfriendly products that can damage fabrics, are not aesthetically pleasing, and pose safety risks, especially for children, as they can be harmful if ingested and may cause fabric deterioration or injury from external impacts.
Innovation Solution
A wooden patch with a laser-processed pattern and a self-adhesive resin patch is used, where the wooden accessory portion is made from materials like medium density fiberboard, laminated wood, or particle board, and the laser system forms raised and depressed portions without thermal transformation, allowing for adherence to fabrics without damage and providing natural beauty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If wood is used to form accessories, then environmentally-friendly and natural beauty is provided, but the wood may shrink or twist when being dried and has poor solidity
Solution Approach 1:
The patent uses engineered wood products (MDF, laminated wood, plywood, particle board) which are composite materials that combine wood fibers or veneers with binders or adhesives. These composite structures provide both environmental friendliness and improved structural stability, preventing the shrinking and twisting issues of natural wood while maintaining natural aesthetics.
2Ease of manufacture
If accessories are formed by melting or pressing materials, then predetermined shapes are formed, but thermal transformation range is created and materials are deteriorated
Solution Approach 1:
The patent replaces traditional mechanical pressing and thermal molding systems with a laser-based system. The laser selectively removes material through ablation to create raised and depressed portions without applying heat that would cause thermal transformation or material deterioration, enabling precise pattern formation on wooden accessories.
3Strength
If pin is used to fix accessory to fabric panel, then accessory is fixed, but pin may deteriorate the fabric panel and wearer may be hurt
Solution Approach 1:
The patent extracts and removes the harmful pin element from the accessory structure. Instead of using pins that penetrate and damage fabric, the invention uses surface-level raised portions combined with adhesive resin patches that provide secure attachment without penetrating the fabric panel, eliminating both fabric deterioration and injury risks.
4Manufacturing precision
If laser system processes wooden accessory portion, then intricate patterns are formed, but thermal damage may occur
Solution Approach 1:
The patent employs periodic or pulsed laser action to process the wooden accessory portion. By using pulsed laser beams with controlled duration and intervals, the system achieves precise material removal for intricate patterns while allowing heat dissipation between pulses, preventing thermal accumulation and damage to the wood material.
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 enables the creation of environmentally friendly, aesthetically pleasing wooden patches that can be securely attached to fabrics without damaging them, while avoiding the safety hazards associated with traditional materials, and allows for intricate patterns and designs without cracking or thermal damage.
Implementation Method 1
the at least one raised portion and one depressed portion are formed by performing a scanning operation with different laser beam depths according to the input pattern by the laser system

AI summary
The present invention relates to a wooden patch and a manufacturing method thereof using a laser. The wooden patch is adhered to clothes, shoes, and headgear as an accessory. In the manufacturing method, since a predetermined pattern is processed on the wooden patch by a laser, the wooden patch may be cut out without cracks or thermal transformation, raised and depressed portion may be variously formed, and grayscales may be realized. In addition, since a resin patch portion is provided to a rear surface of the wooden patch and the wooden patch is adhered to a product by a self-adhesive characteristic or a thermal process, a fabric panel may not be deteriorated, and a wearer may not be hurt. Further, environmentally-friendly beauty may be provided.
