Solution Overview
Problem
Smart keys for vehicles face rigidity issues when made thinner, making them vulnerable to breakage due to reduced thickness.
Innovation Solution
A smart key design that includes a substrate part with a key accommodation part, a reinforcement part coupled to the substrate for enhanced rigidity, and a case part that covers the substrate, reinforcement part, and key accommodation part, with the reinforcement part extending along the substrate's length to provide additional structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the smart key is manufactured to be thinner, then the portability and sleekness are improved, but the rigidity is deteriorated and the smart key becomes vulnerable to bending
Solution Approach 1:
The patent employs a composite structure combining a flexible substrate part with rigid reinforcement parts. The reinforcement parts are coupled to the substrate part to provide structural support and prevent bending, while allowing the overall key to maintain a thin profile. This composite approach enables the smart key to achieve both thinness and sufficient rigidity.
2Volume of moving object
If the thickness of the smart key is decreased, then the sleekness is improved, but the smart key becomes vulnerable to breakage
Solution Approach 1:
The smart key is divided into multiple functional parts: a substrate part containing electronic components, reinforcement parts for structural support, a key accommodation part for the physical key, and a case part for protection. This segmentation allows each part to be optimized independently - the substrate can be thin for sleekness while reinforcement parts provide breakage resistance.
Solution Approach 2:
The reinforcement parts are pre-coupled to the substrate part to provide structural support before the smart key is subjected to bending or breaking forces. This preemptive reinforcement prevents damage by distributing stress across the reinforced structure rather than allowing it to concentrate in the thin substrate.
3Strength
If reinforcement parts are added to augment rigidity, then the strength is improved, but the device complexity increases
Solution Approach 1:
The reinforcement parts are integrated with the substrate part through coupling, forming a unified structural assembly. The key accommodation part is also coupled to the substrate part, merging multiple functions (structural support, component mounting, key storage) into a single integrated device. This reduces the number of separate components and simplifies assembly.
