Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional knob structures use complex components and methods to generate signals through electrical relationships, then signal generation capability is achieved, but manufacturing cost increases
Solution Approach 1:
The patent merges multiple pad groups (ring pads, inner pads, outer pads) onto a single substrate, integrating what would traditionally be separate components into one unified structure. This reduces the number of discrete parts and simplifies assembly, directly addressing the manufacturing cost issue while maintaining full signal generation capability through the combined pad groups
Solution Approach 2:
The substrate serves multiple functions simultaneously: it provides the structural base, holds all pad groups (ring, inner, outer), establishes electrical connections between pads and the touch control display panel, and enables detection of multiple operational states (pressing, rotating, touching). This multi-functionality eliminates the need for separate dedicated components for each function, reducing overall complexity and manufacturing cost
2Adaptability or versatility
If multiple pad groups are arranged on the substrate, then operational versatility is enhanced, but device complexity increases
Solution Approach 1:
The pad structure is segmented into three distinct groups (ring pads, inner pads, outer pads) with different spatial arrangements and functions. This segmentation allows each group to be optimized for specific operational states (pressing, rotating, touching) while maintaining clear functional boundaries that simplify the overall design and control logic
Solution Approach 2:
The patent transitions from conventional two-dimensional pad arrangements to a three-dimensional spatial configuration with pads at different radial distances from the center (ring, inner, outer groups). This dimensional approach enables simultaneous detection of multiple operational states without requiring additional complex components, as each spatial level corresponds to different operational modes

Function Achieved in This Case
The structure simplifies manufacturing by reducing complexity and enables efficient generation of multiple signals for touch control display panels, enhancing operational versatility.
Implementation Method 1
Two contact ends of each of the conductive spring pieces correspond in position to the first ring configuration region, the second ring configuration region, and the third ring configuration region, and each of the conductive spring pieces can be electrically coupled to the ring pad, the inner pads, and the outside pads
Data Source
AI summary
A knob structure can be installed on a touch control function display and includes a seat, a substrate, a trigger element, and an operating cover. The substrate is disposed on the seat, and includes a carrier, a ring pad, and a plurality of inner pads and outside pads. The carrier has first, second, and third ring configuration regions that jointly define a center. The inner pads are disposed on the second ring configuration region. The inner pads are spaced apart and electrically coupled. The outside pads are disposed on the third ring configuration region. The outside pads are spaced apart and electrically coupled. The trigger element can be operated to electrically couple the ring pad, and at least one of the inner pads and the outside pads, and sends a first signal, a second signal, or a third signal to the touch control display panel.
