Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional touch pad structure is used, then the device structure is simple, but the feedback comfort is insufficient
Solution Approach 1:
The surrounding frame is divided into multiple frame parts (first frame parts and second frame parts) that are spaced apart, allowing independent elastic members to be positioned between them. This segmentation enables localized feedback mechanisms while maintaining overall structural integrity, resolving the contradiction between feedback comfort and structural simplicity.
Solution Approach 2:
Elastic members are strategically positioned between specific frame parts to provide localized feedback forces at key touch regions. The fixing member with extension parts anchors these elastic members at precise locations, ensuring that feedback is optimized where needed without requiring complex structures throughout the entire device.
2Manufacturing precision
If elastic members are added to improve feedback, then feedback uniformity improves, but device complexity increases
Solution Approach 1:
The feedback function is extracted into separate elastic members that are positioned between frame parts, rather than integrating feedback mechanisms into the main touch pad structure. This extraction allows for standardized, uniform feedback across different regions while keeping each elastic member as a simple, manufacturable component.
Solution Approach 2:
The frame parts serve multiple functions: they provide structural support, define spacing for elastic members, and work with the fixing member to anchor the feedback mechanism. This multi-functionality reduces the need for additional specialized components, maintaining manufacturing simplicity while achieving uniform feedback.
3Stability of the object's composition
If multiple frame parts are used to position elastic members, then feedback consistency improves, but assembly complexity increases
Solution Approach 1:
The fixing member combines multiple extension parts that extend in different directions to simultaneously anchor multiple elastic members. This merging of anchoring functions into a single component simplifies assembly, as the fixing member can be installed once to secure all elastic members in their proper positions, ensuring feedback consistency without requiring multiple separate assembly steps.

AI summary
A full-area touch panel device includes two first frame parts and two second frame parts. Two elastic members are disposed between the first frame parts and are connected to the second frame parts. Each elastic member includes threaded holes and positioning rings that protrude downwardly from a bottom surface of the elastic member and that respectively surround the threaded holes. A fixing member includes a main body part, first extension parts, and second extension parts. A thickness of the main body part is greater than a thickness of each of the first extension parts and the second extension parts. The main body part has through holes that are respectively aligned with the threaded holes of the elastic members and that are respectively engaged with the positioning rings of the elastic members.
