Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic device manufacturers face challenges in thinning the structure of elastic bodies while maintaining reliability, as existing designs compromise on thickness and structural integrity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the structure of the elastic body is thinned to meet electronic device thinning requirements, then the overall thickness of the device is reduced, but the reliability and structural integrity of the elastic body deteriorates
Solution Approach 1:
The elastic body is divided into distinct functional segments: a bottom plate with opening, a position limiting portion extending from the bottom plate, and an elastic part connecting between them. This segmentation allows each part to be optimized independently - the bottom plate provides structural support while the elastic part provides flexibility, resolving the contradiction between thinning and reliability
Solution Approach 2:
The elastic part is nested within the space defined by the bottom plate opening and position limiting portion. When external force is applied, the elastic part accommodates within the opening, allowing the overall structure to maintain thin profile while preserving the elastic function through proper nesting of components
2Length of stationary object
If the elastic part is made thinner to reduce overall device thickness, then the thinning design requirement is fulfilled, but the ability to maintain stable electrical connection deteriorates
Solution Approach 1:
Different regions of the elastic body have different thickness and structural properties. The bottom plate and position limiting portion have sufficient thickness for structural support, while the elastic part is thinner for flexibility. This local quality differentiation allows the thin elastic part to maintain stable electrical connection while fulfilling thinning requirements
Solution Approach 2:
The elastic body combines multiple functional elements (bottom plate, position limiting portion, elastic part) into a composite structure that integrates both mechanical support and electrical conduction functions. This composite approach allows the thin elastic part to maintain reliability through the supportive framework of the other components
3Ease of manufacture
If the elastic body structure is simplified to reduce manufacturing complexity, then manufacturing ease is improved, but the ability to prevent excessive deformation deteriorates
Solution Approach 1:
The segmented structure with clearly defined bottom plate, position limiting portion, and elastic part provides inherent deformation control through geometric constraints. The position limiting portion extending toward the opening creates natural boundaries that prevent excessive deformation while maintaining manufacturing simplicity through the modular design
Solution Approach 2:
The position limiting portion is designed with specific dimensional parameters (extension length, distance from opening) that control the deformation characteristics of the elastic part. By optimizing these parameters, the structure achieves proper deformation control without complex manufacturing processes
