Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch sliders on electronic devices suffer from long finger sliding distances and recognition times due to equal-sized sensing points, leading to inefficiencies in processor wake-up and recognition speed.
Innovation Solution
A touch sensing assembly with unequal-sized sensing areas, where the first sensing areas at the ends are larger than the second sensing areas in the middle, allowing for rapid recognition and improved processor wake-up success rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If equal-sized sensing points are used for multi-point detection, then the layout is simple and manufacturing is easy, but the finger sliding distance is long and recognition time is extended
Solution Approach 1:
The sensing assembly uses different sensing area sizes at different locations: larger sensing areas at the two ends of the sliding gesture area and smaller sensing areas in the middle. This local differentiation allows the finger to be detected more quickly when it enters or exits the sliding area (at the ends), reducing overall recognition time while maintaining manufacturing feasibility.
2Ease of manufacture
If equal-sized sensing points are used, then the structure is uniform and easy to manufacture, but the processor wake-up success rate is reduced
Solution Approach 1:
Larger sensing areas are positioned at the two ends of the sliding gesture area where the finger most commonly enters and exits. This increases the probability of detecting the finger at these critical locations, thereby improving the processor wake-up success rate when the device transitions from sleep mode, while the overall structure remains relatively simple for manufacturing.
3Productivity
If larger sensing areas are used at the ends, then the processor wake-up success rate improves and recognition speed increases, but the device complexity increases
Solution Approach 1:
The sensing assembly employs an asymmetric layout where sensing areas at the two ends are larger than those in the middle. This asymmetric design optimizes recognition speed by placing larger detection areas at the entry and exit points of the sliding gesture, while the increased complexity is minimal and confined to the sensing area dimensions rather than the overall system architecture.

AI summary
The present disclosure relates to a touch sensing assembly and an electronic device, including a sliding gesture area, wherein the sliding gesture area includes at least one first sensing area located at each end of the sliding gesture area, and at least one second sensing area located in the middle of the sliding gesture area. The dimension of the first sensing area is larger than the dimension of the second sensing area. The layout of unequal-sized sensing areas on the sliding gesture area is adopted in the present disclosure, so that the success rate of the wake-up of the processor after sleep can be ensured, and the effect of rapid recognition of the sliding action can be achieved.
