Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional key holders with a ring shape allow keys to move freely, resulting in noisy jangling sounds.
Innovation Solution
A keycase design featuring a longitudinal top and bottom plate connected by a flexible connector, with a key post and fastener to securely hold keys, and a key pushing liner to prevent key movement and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keys are held in a ring-shaped key holder, then keys can be conveniently carried, but keys move freely and produce noisy jangling sounds
Solution Approach 1:
The keycase is divided into separate functional components: a body portion for holding keys, a lid portion for closure, and a connector for attachment. This segmentation allows each part to perform its specific function effectively - the body portion with its liner prevents key movement and noise, while the lid provides secure closure.
Solution Approach 2:
A liner is introduced as an intermediary element between the keys and the body portion of the keycase. This liner fits within the body portion and provides a surface that prevents keys from moving freely, thereby eliminating the jangling noise while still allowing keys to be conveniently stored and accessed.
2Device complexity
If a traditional key holder design is used, then the structure is simple, but keys cannot be securely held and may be lost
Solution Approach 1:
The invention combines multiple security features into a unified keycase structure: a closure lid that covers the key storage area, a connector that securely attaches the lid to the body, and a liner that prevents key movement. This merging of features provides comprehensive key security while maintaining a relatively simple overall structure.
Solution Approach 2:
The liner is pre-installed within the body portion of the keycase before keys are inserted. This preliminary action ensures that when keys are placed in the keycase, they are immediately prevented from moving freely, providing security from the moment of insertion without requiring additional steps or complex mechanisms.
3Volume of moving object
If keys are stored in a compact key holder, then portability is improved, but accommodation for various numbers of keys is limited
Solution Approach 1:
The keycase is designed with dynamic adjustability through the connector mechanism, which allows the lid to be attached at different positions along the body portion. This dynamic feature enables the keycase to accommodate varying numbers of keys while maintaining a compact form factor, as the connector position can be adjusted to optimize the internal space for different key quantities.
Solution Approach 2:
The connector is designed with multiple attachment positions or adjustable characteristics that allow changes in the effective volume and configuration of the keycase interior. By changing the connector position or orientation, the keycase can adapt its internal space to accommodate different numbers and sizes of keys, maintaining compact external dimensions while providing versatile internal accommodation.
