Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keys with single functions become complex and cumbersome when attempting to incorporate multiple functions, limiting their usability and structural simplicity.
Innovation Solution
A digital encoder with a screen that integrates a key body, display assembly, rotating assembly, rotary encoder sensor, and pressing element, allowing for both pressing and rotating actions to be sensed and displayed, enabling multiple functions such as pressing, rotation, and touch control through modular assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functions are added to a conventional key, then the functionality and versatility are improved, but the structural complexity and ease of manufacture deteriorate
Solution Approach 1:
The patent combines multiple functional components (pressing element, rotating assembly, display assembly, rotary encoder sensor) into a single integrated key body structure. This merging approach allows the key to perform multiple functions (pressing, rotating, displaying) without requiring separate control units or complex wiring, thereby improving versatility while controlling structural complexity
Solution Approach 2:
The key body is designed as a universal control unit that can perform multiple operations: pressing actions activate the pressing element, rotating actions engage the rotary encoder sensor, and the display assembly provides visual feedback. This multi-functional design allows a single component to replace what would traditionally require multiple separate controls
2Adaptability or versatility
If multiple functions are added to a conventional key, then the versatility is improved, but the ease of operation deteriorates due to increased complexity
Solution Approach 1:
Different regions of the key body provide different interaction modes: the top surface allows pressing operations, the side edge allows rotating operations, and the display assembly provides visual feedback in a specific location. This spatial differentiation of functions allows users to intuitively understand and operate each function without confusion, maintaining ease of operation despite multiple capabilities
3Loss of information
If a display assembly is added to the key, then the information feedback capability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The display assembly is nested within the key body structure, with the display element positioned in a dedicated cavity and the display circuit element integrated into the same housing. This nesting approach allows the display components to be compactly arranged without increasing the overall footprint of the key, and simplifies wiring by keeping the display circuit close to the display element

AI summary
A digital encoder with a screen includes a key body, and a display assembly is configured inside the key body. The display assembly includes a display carrier assembly, display element configured on the display carrier assembly and display circuit element configured in the display carrier assembly, where one side of the display assembly is in connection with a rotating assembly movably configured on a carrier housing, and a rotary encoder sensor and pressing element are configured between the rotating assembly and carrier housing, thereby allowing the assembly of the key body to be more convenient through modulization structures, and allowing the key body to have multiple functions of display, press and rotation at the same time to increase use convenience.
