Solution Overview
Problem
Existing game controllers require multiple internal detection means to measure the insertion degree of a length, which complicates the design and operation.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple internal detection means are disposed to detect insertion degree, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The detection means is extracted from the internal structure and relocated to the external periphery of the controller body. This allows a single external detection means to measure the insertion degree of the length inserted into the flexible member, eliminating the need for multiple internal detection means while maintaining measurement accuracy.
Solution Approach 2:
The flexible member acts as an intermediary element that transmits the insertion motion of the length to the external detection means. The detection means measures the position of the length through the flexible member's deformation, enabling indirect measurement without direct contact with multiple internal sensors.
2Reliability
If dedicated size arrangement for flexible members is used, then detection reliability is improved, but adaptability deteriorates
Solution Approach 1:
The external detection means is designed to universally measure the insertion degree of lengths with different sizes and shapes inserted into the flexible member. The detection system remains reliable across different flexible member configurations because it measures the actual insertion position rather than relying on predetermined size arrangements.
Solution Approach 2:
The flexible member's deformation characteristics are dynamically adapted to accommodate different length sizes. The external detection means dynamically measures the actual insertion position regardless of the flexible member's specific dimensions, enabling the system to adapt to various configurations while maintaining detection reliability.

AI summary
To provide a game controller with which a detection means for detecting an insertion degree of a length can be simplified. A game controller includes a controller body to which is attached a flexible member having formed therein an insertion hole into which a length is inserted, a laser transmitter/receiver that is installed on an outer periphery of the controller body and measures a distance with respect to a base surface of the length by transmission and reception of a wave to detect an insertion degree of the length inserted from the insertion hole, and a wiring cable and a control circuit that output the insertion degree of the length detected by the laser transmitter/receiver.
