Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available cases for tablet-shaped devices often fail to meet consumer needs and are costly to manufacture, with manufacturing tolerances affecting their performance and usability.
Innovation Solution
A tablet case with a magnetically attracted flap that can be configured between a protective and a stand mode, using different materials and processes for the body and flap, and featuring a design with magnetic orientation reversal and stability-providing legs to address manufacturing tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If commercially available cases are manufactured with tight tolerances to ensure proper fit and function, then reliability is improved, but manufacturing cost increases
Solution Approach 1:
The case is divided into separate components (body, flap, legs) that can be manufactured independently with relaxed tolerances and then assembled. The body receives the tablet, the flap provides magnetic closure, and the legs provide stability, allowing each part to be optimized separately for cost-effective manufacturing.
Solution Approach 2:
The design changes from requiring tight dimensional tolerances for overall case fit to using magnetic attraction strength as the primary securing mechanism. The magnetic force between the flap and body provides reliable closure without requiring precision-machined fitting surfaces, significantly reducing manufacturing complexity and cost.
2Adaptability or versatility
If a case design includes multiple configurations (protective and stand modes), then adaptability is improved, but device complexity increases
Solution Approach 1:
The flap serves multiple functions: it provides magnetic closure for the protective configuration and folds to form a stand for viewing configurations. The legs provide both structural support and stability in both configurations. This multi-functionality reduces the need for separate components for each feature, simplifying the overall design while maintaining versatility.
Solution Approach 2:
The case transitions from a static protective shell to a dynamic structure with movable flap and adjustable stand angle. The magnetic connection allows the flap to be easily repositioned between closed and stand configurations, providing adaptability without complex mechanical mechanisms.
3Ease of operation
If magnetic attraction is used to secure the flap, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The magnetic components are integrated into molded plastic parts rather than requiring precision-machined metal components. The magnets are embedded in the flap and body during injection molding, allowing for cost-effective manufacturing with standard tolerances. This approach prioritizes ease of operation while accepting moderate manufacturing precision through process integration.
