Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cases for portable electronic devices, such as tablets, often lack ease of use and effective protection, particularly in terms of shock absorption and handling convenience.
Innovation Solution
A portable electronic device case comprising a first frame and a second frame that removably couple to form a case with integrated shock absorption features, a retractable handle, and a stand, made from a combination of hard and soft materials for enhanced structural rigidity and grip, allowing secure containment and versatile use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional cases use simple single-material construction, then manufacturing is easy and cost is low, but shock absorption capability and structural rigidity are insufficient
Solution Approach 1:
The case combines hard materials (polycarbonate, acrylic, or metal) for structural rigidity with soft materials (thermoplastic polyurethane, thermoplastic elastomer, or silicone) for shock absorption. This composite construction allows the case to simultaneously achieve impact resistance and structural integrity, resolving the contradiction between strength and complexity by using material composition rather than mechanical complexity.
Solution Approach 2:
Different portions of the case are made from different materials optimized for their specific functions: the outer shell uses hard material for protection and rigidity, while the inner lining uses soft material for shock absorption and device protection. This local differentiation of material properties allows each region to perform its intended function effectively without requiring complex overall结构设计.
2Adaptability or versatility
If conventional cases add protective features and accessories, then protection and versatility improve, but ease of operation and handling convenience deteriorate
Solution Approach 1:
The case integrates multiple functions into a single unified structure: the shock-absorbing material is incorporated directly into the case construction, the handle is attached to the case body, and the stand is built into the case framework. This merging eliminates the need for separate protective devices and accessories, improving handling convenience while maintaining versatility.
Solution Approach 2:
The case is designed to perform multiple functions simultaneously: it provides shock absorption through integrated soft material, offers improved handling via an attached handle, and enables various viewing angles through an integrated stand. This multi-functionality within a single device improves versatility without requiring multiple separate components that would complicate operation.
3Stability of the object's composition
If conventional cases use hard materials only, then structural rigidity is good, but shock absorption and grip quality are insufficient
Solution Approach 1:
The case uses a composite material system where hard materials (polycarbonate, acrylic, or metal) provide structural rigidity and stability, while soft materials (thermoplastic polyurethane, thermoplastic elastomer, or silicone) provide shock absorption. This combination allows the case to resist both static loads and dynamic impacts effectively.
Solution Approach 2:
The case changes the material parameter of hardness/softness by using different materials for different portions: hard materials for the outer shell to maintain structural rigidity, and soft materials for the inner lining to absorb shock impacts. This parameter differentiation allows simultaneous achievement of rigidity and shock absorption.
