Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information output apparatuses face challenges in providing durability and waterproof functionality, especially when used in environments where they are exposed to moisture or contaminants, which can lead to deformation and reduced effectiveness.
Innovation Solution
The design incorporates a casing with protrusions and a driving module, a skin module with a flexible film for protection, and a cover plate that includes a rigidity module and recesses to maintain waterproofing and durability, allowing the apparatus to be used in wet conditions or as a wearable device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible film is used for the skin module to provide waterproof function, then waterproof capability is improved, but structural rigidity deteriorates causing deformation during assembly and use
Solution Approach 1:
The skin module combines a flexible waterproof film with a rigid support plate to create a composite structure. The support plate provides structural rigidity and prevents deformation during assembly and use, while the waterproof film maintains the waterproof barrier. This composite approach resolves the contradiction by integrating materials with complementary properties.
Solution Approach 2:
The rigid support plate is positioned specifically at the circumferential region of the skin module where structural strength is most needed to prevent deformation. The flexible film covers the entire surface including the active display region where flexibility and waterproofing are paramount. This localized application of different material properties optimizes both rigidity and waterproofing.
2Stability of the object's composition
If the skin module is made completely rigid to prevent deformation, then structural stability is improved, but waterproof sealing capability deteriorates due to lack of flexibility
Solution Approach 1:
The combination of rigid support plate and flexible waterproof film creates a composite skin module that exhibits both structural stability and sealing flexibility. The rigid plate maintains shape and position, while the flexible film conforms to surfaces and maintains waterproof seals, resolving the contradiction between rigidity and sealing capability.
Solution Approach 2:
The skin module is segmented into two functional layers: a rigid support plate for structural stability and a flexible waterproof film for sealing. This segmentation allows each layer to perform its specialized function optimally without compromising the other.
3Reliability
If the cover plate is designed to completely cover the skin module for protection, then durability is improved, but tactile sensitivity deteriorates due to reduced contact area
Solution Approach 1:
The cover plate is designed with selective coverage: it protects the circumferential region of the skin module where durability is most needed, while leaving the active display region exposed or partially exposed. This allows tactile interaction with the protrusions in the active region while maintaining protective coverage over the less sensitive peripheral areas.
Solution Approach 2:
Instead of completely covering the skin module, the cover plate provides partial coverage focused on the regions where protection is most beneficial. This partial action maintains tactile sensitivity in the active display area while providing sufficient protection to achieve improved durability overall.

AI summary
An information output apparatus is proposed. The apparatus may include a casing comprising an expression surface and expression holes provided in the expression surface, protrusions configured to reciprocate so that at least a portion of each of the protrusions protrudes from a corresponding expression hole of the expression holes to display information on the expression surface. The apparatus may also include a driving module located inside the casing, connected to the protrusions, and configured to move the protrusions. The apparatus may further include a skin module comprising a film located opposite the expression surface, and a cover plate disposed along a circumference of the skin module to cover at least a portion of the circumference of the skin module.
